Automotive Industry Applications:

Automotive – Evaporative Emissions

Vehicle activated carbon canisters are designed to capture fuel emissions generated by the evaporation of the fuel tank vapors during day to night temperature variations. Emission regulations vary throughout the world. In the United States (US), requirements call for capturing fuel vapors generated during a 72-hour test, while in the European Union requirement are for a 24-hour test. Fuel vapor generation rates are approximately 25 to 30 grams a day for a mid-size vehicle. Our granular activated carbons are used by leading industries for this application because of their superior volumetric cost, performance and proven durability.

Automotive – ORVR

On-Board Refueling Vapor Recovery (ORVR) is a U.S. regulation that requires the capture of fuel vapors generated during vehicle refueling events. ORVR presents a unique challenge for the vehicle by requiring the canister to have high fuel vapor capacity at fast loading rates and low pressure drop. ORVR canisters are typically two to three times the size of a standard evaporative emissions canister because of these capacity requirements. Our carbon pellets are the industry standard for this application due to their high capacity, durability and low pressure drop. Further, our special grade of Boycecarbon helps to reduce canister size due to its industry leading capacity.

Automotive – PZEV

Partial Zero Emission Vehicle (PZEV) is a California initiated emission category that is expanding across the country. PZEV requires the vehicle’s fuel system to have no more than 54 mg of emissions during a 72-hour test. PZEV presents a unique challenge to control canister bleed emissions to very low levels, typically less than 10 mg. Boyce special grades gives solution to control canister bleed emissions.

Two-Wheelers

There is a global expansion of canisters on motorcycles to control fuel tank evaporative emissions generated by the evaporation of the fuel tank vapors during the day to night temperature variations. These canisters are typically much smaller than an automotive canister. Our granularactivated carbons are chosen for this application throughout the world for their superior volumetric cost and performance and proven durability.

Air Induction Systems

Vehicle regulations in the U.S. sometimes necessitate the control of vapors emitted through the vehicle’s air induction systems. Unique solutions are required to solve these emissions because of the high airflow within the AIS and the potential to affect engine performance if these airflows are inhibited. Our uniquely designed granular and powder carbon are used to reduce hydrocarbon emissions to targeted levels.

Small Off-Road Engines Fuel tanks for weed trimmers, leaf blowers, lawn mowers, generators and similar products are being mandated to control fuel evaporative emissions. Our granular activated carbons are chosen for this application for their superior volumetric cost and performance and proven durability.

Marine

The U.S. Environmental Protection Agency (EPA) is evaluating evaporative emission control regulations for recreational boats.

Cabin Air (Vehicle Interiors)

Exposure to volatile organic compounds that off-gas from interior components in new vehicles is of increasing concern in many parts of the world. Recent tests have demonstrated significant reductions of VOCs in the cabin by the use of activated carbon sheets. Boyce supplies special grades of activated carbon to make activated carbon sheets. This confirms ACS as a low-cost and effective method for reducing VOC content in the cabin before delivery to the consumer.

Hybrid Electric Vehicles and Plug-in Hybrid Electric Vehicles

 Automotive equipment manufacturers are increasingly turning to advanced engine technology to increase fuel economy. HEV and PHEV, while allowing for improved fuel economy, present a unique challenge for the activated carbon canister primarily due to severely restricted purge volumes. While our carbons are recognized for their superior purge performance, to meet the challenges of HEV and PHEV our carbons are typically combined with activated carbon honeycombs to meet emission targets.

Gasoline Direct Injection Engines

Gasoline Direct Injection Engines (GDI), while allowing for improved fuel economy, present a unique challenge for the activated carbon canister primarily due to reduced purge volume. Our carbons are recognized for their superior purge performance to meet most global GDI canister challenges. Additionally, our carbons are combined with our activated carbon to meet PZEV level emission targets.

Fuel Loading/Transfer Facilities

Bulk fuel and chemical transfer facilities use large-scale activated carbon absorbers to capture the vapors that are displaced or generated during the liquid transfer. The characteristics that make Boyceproducts the premier activated carbon for automotive evaporative emissions control apply to fuel loading as well.

The Greener side of Carbon

Innovation or the ‘turning of good ideas into competitive solutions for society’ is an INVESTMENT which only competitive industries are able to accommodate. Sustainability, is the ability to be maintained, and needs to be kept alive without being overlooked. The triangle of sustainability acts on three pillars; economic, social and environmental.

At Boyce Carbon we constantly fsund research projects that lead to innovation; innovation to increase the life of our resources like water and air. Innovation for sustainability works hand in hand, like the sun and water for the growth of nature. At Boyce, we constantly seek to explore the green side of carbon, to innovate for sustainability. Boyce Carbon is a company into sustainability based solutions and products. We work towards identifying and procuring carbon based products that are used across industry like food processing, pharmaceutical, water management and treatment, chemical and other industry applications.

We source from the optimal sources with a technical orientation on the product. The sourcing is done from the best sources networked across Asia, India, Srilanka, Philippines, Indonesia and Malaysia. Our comprehensive product range includes activated carbon and coconut shell based products.

COCONUT SHELL IS MORE EFFICIENT

Activated carbons produced from coconut shells typically have a tighter, more micro porous pore structure than their coal-based counterparts. This is due to the inherent pore structure of the raw material coconut shell as compared to raw material coals. This micro porosity lends itself towards certain applications where activated carbon is used. Also, coconut shell-based carbons tend to be harder, more resistant to abrasion, and lower in ash than similar grades of coal-based carbons. A quick comparison of standard specification measures on coconut shell carbons versus coal carbons is as follows: A complete range of premium virgin activated carbons made from high quality coconut shell charcoal, and Coconut Shell Charcoal in granular and powder forms are available in the form of Coconut Shell Cakes, Desiccated Coconut, Coconut shell charcoal Briquettes, Coconut Shell Charcoal Granules, Coconut Shell Charcoal Lumps, Coconut Shell Charcoal Powder, Coconut shell powder, Coconut shell chips, etc. The company has been certified for ASNI/NSF, Standard 61 and ISO 9001 and satisfies the requirements of the Food Chemical Codex.

Boyce is uniquely equipped to supply a full range of activated carbon products

for variety of applications in refineries. We currently supply best quality of Granular and powder activated carbon for dozens of refineries, offering prompt, expert service. Regulatory compliance and the desire to improve product quality are key drivers for the use of activated carbon in Refineries.

The following discussion highlights these common applications and the solutions that Boyce Carbon can supply.

VOC Treatment & Control:

Compliance with either the Benzene National Emission Standard for Hazardous Air Pollutants (NESHAP) regulation or local air emission regulations drives the need for VOC control at several emission points within the refinery, including:

v  Sewer pumps / junction boxes

v  Covered API separators and DAF units (level changes and diurnal breathing losses) Vacuum truck exhaust

v  Wastewater and storm water storage tanks (level changes and diurnal breathing losses)

Boyce activated carbon grades are particularly designed for these applications to be used in carbon adsorption units.

Vapor / Solvent Recovery:

Activated carbon is often used in systems designed for the recovery of economically valuable products (gasoline vapors, benzene, and solvents) at refineries and terminals. Both pressure swing (for gasoline vapors) and temperature swing (for benzene and solvents) designs are commonly used. In this application, Boyce  special grades of activated carbons with high working capacities allows for effective adsorption and desorption through numerous cycles.

Hydrogen Sulfide Removal

The processing of sour crude oil often results in the formation of hydrogen sulfide (H2S) at various points in the refinery. Activated carbon is a common technology to control the nuisance odors and corrosion issues that often result from H₂S. Boyce Specialty grades of carbon are often used to enhance the H₂S capacity.

Amine Purification:

Various alkanolamines are used by refineries to purify gas streams by removing acid gases such as CO₂, H₂S, and COS. During this process, the amine solution picks up hydrocarbons and organic acids. Activated carbon is utilized to treat a slipstream of the amine solution to prevent buildup of these hydrocarbons, and provides several benefits to the refinery:

v  Improved amine scrubbing efficiency

v  Reduced corrosion rate

v  Reduced operating costs

Decolorization

Boyce Activated carbon is the perfect choice to remove unwanted color or other organic impurities from desired end products such as jet fuel, kerosene, gasoline, lube oil, and other products.

Boyce Granular activated carbon is produced from coconut shell charcoal by the process of STEAM activation.  It gives the necessary hardness to avoid excessive losses due to attrition and handling. They present large internal surface of pore structure, ensuring high adsorption power in specific purposes and uses. They are used in fixed or moving beds as columns where the liquid or gas passes through and gets purified. They can be used in liquid or gas phase continuous adsorption process and offer unusual economy in cases where carbon regeneration is favorable.

Process of Recycling in Textile Industry

Developments in wastewater treatment methods

Waste water from the textile finishing industry commonly contains moderate concentrations (10-200 mg/l) of dye stuffs, contributing significantly to the pollution of aquatic ecosystems. Various physio-chemical and biological techniques can be employed to remove dyes from waste water. The technical and economic feasibility of each technique is determined by several factors such as dye type, waste water composition, operation costs and generated waste products.

The adsorption technique is superior to other techniques with regard to simplicity of design, initial cost, ease of operation and insensitivity to toxic substances. This technique uses activated carbon and other suitable sorbents. Activated carbon remains the most effective and widely used adsorbent for the decolourisation of waste water from textile industries.

Textile Recycling

Process of recycling in textile industry using biological activated carbon treatment system

In this bio treatment method, naturally occurring micro organism breakdown materials in the water such as Dissolved Organic Carbon (DOC), Biochemical Oxygen Demand (BOD), turbidity, Total Suspended Solid and nutrient levels and thus improve water quality. The Activated carbon filters are used to provide a place on which these microorganisms grow. Because of the low price of bio treatment, the combination with AC may reduce the overall treatment cost. Finally the biologically activated carbon systems degrade the industrial waste water in a fast and inexpensive way.

There are 2 types of biologically activated carbon systems for waste water treatment in textile industries. In the first type, biological activated carbon (BAC) filter uses granular activated carbon to reduce dissolved organic matter and remove color (20 to 30 mg/L ozone for 0.5 to 1 hour). While in the second, biological activated carbon filter (BAC) uses activated carbon in the form of flexible clothes to reduce dissolved organic matter (20 to 30 mg/L ozone for 0.5 to 1 hour).

The two biological activated carbon treatment systems successfully reduce the levels of BOD5, COD, DOC, TSS, Color and Turbidity in the wastewater to within the specified guidelines in each trial that is continuously providing high quality recycled water to the entire factory requirements. The improvement of water quality by the two BAC filters under different conditions is tabulated below (Table 1.). Biological oxidation within GAC filters also can be efficient for the removal of inorganic such as ammonia. Ammonia is a toxic chemical which promotes bio-growth and reacts with chlorine. The combined removal of DOC and ammonia leads to a significant reduction of the chlorine demand of the finished water. The amount of DOC removal and oxygen consumption by the two BAC in warm temperature (25-34 oC) are much greater than cold temperature (9-17 oC.)

Table (1): Removal Efficiency of Two of Biological Activated Carbon Systems.

Parameter	BAC1	BAC2
Biochemical Oxygen Demand after 5 Days, BOD5(mg/L)	75% to 88%	81% to 92%
Chemical Oxygen Demand, COD(mg/L)	68% to 81%	63% to 87%
Dissolved Organic  Carbon, DOC(mg/L)	66% to 89%	71% to 93%
Total Suspended Solid, TSS	87% to 94%	61% to 80%
Color(TCU)	More than 80% of the color	More than 81% of the color
Turbidity(NTU)	75% to 88%	68% to 81%

Boyce supplies wide range of activated carbon with an exceptionally high surface area and a high degree of micro porosity makes it very suitable for these textile industries for the removal of dyes in efficient way.

Why should you look at buying activated carbon and charcoal from India?

The Government of India considers the exports of coconut shell products

Well, first of all one should know what activated carbon actually is.  It is an eco friendly  water treatment medium, which is found in granulated, block, or powdered form, produced by heating carbonaceous materials, such as coal, wood, or coconut shells, in the absence of air, creating a highly porous adsorbent material. Mostly coconut shells are used for this process.

Coming to why activated carbon from India. It is a well known fact that India is the largest producer and exporter of coconut and coconut based products in the world.  India is also the 3rd largest producer of coal.  Here in India, there are 12 major ports and 135 minor ports which are so well connected by a road system that it makes it very easy for transportation.

The Government of India considers the exports of coconut shell products so important that they have a department dedicated to promote export of coconut shell products.  Indian companies, a minimum of at least 100 manufacturers make activated carbon from coal and coconut shell as per specifications of the customer, exporting around 25000 tons of activated carbon and importing 1000 tons of activated carbon every year.  India also has an excellent relationship with countries like Sri Lanka, Malaysia, Indonesia and The Philippines etc, who are also major coconut producing countries.

Coming to the global scenario here, the demand for activated carbon is around 0.50 million tones per annum with a global growth rate of 2 to 3% per annum.  The wood based activated carbon accounts for about 40% of the total production in the world. Cost advantages can be obtained for both coconut shell and coal-based activatedcarbon.

Boyce have learned to control adsorption capacity on gold recovery.

Use of chars in gold recovery began in the late 1800s. The 1930s and 1940s were periods of experimentation in North America, resulting in new or improved approaches for carbon use, both in pulverized and granular form. A major breakthrough was reported by J.B.Zadra of the US Bureau of Mines in 1950. He demonstrated that adsorbed gold and silver values could be desorbed from the carbon by low cost procedures, thereby allowing the carbon to be recovered and recycled to the adsorption circuit.
 The carbon-in-pulp (CIP) process for gold recovery has now been in use for more than a decade. Based on this experience, carbon companies and metallurgists are addressing several of the early concepts about the selection and performance of the activated carbon, particularly as they relate to soluble gold loss and/or subsequent efforts to being soluble losses into line. Carbons used in South Africa and North America for gold recoveries are almost exclusively coconut shell-based granular types which are also very popular in Australia. Typically, 6×12 or 6×16 mesh coconut carbons are used in pulp, and 6 x 16 or 12 x 30 mesh are used in columns.
 In 1970, the US Bureau of Mines investigated bituminous coal-base carbon for gold adsorption. However it was found that coconut carbons would stand up better in a pulp circuit than other base material carbons. Since coconut carbon was available and worked well, granular carbons from other base materials receives minimal importance.
 Selection of activated carbon for gold recovery service includes consideration of:
 (a)Presence of other substances that may affect or interfere with loading of carbon (b)
 Adsorption capacity(c) Rate of adsorption and desorption (d) Residual gold on stripped carbon.
 (e)Resistance to abrasion (f) Reproducibility of test methods (g) Consistency of product for gold recovery service.
 Boyce have learned to control adsorption capacity for gold cyanide, providing carbon possessing consistent gold absorption properties. Some users believe that carbons with high adsorption capacity for gold will not strip to low levels. Plant performance is the best proof of how well high capacity/fast loading carbon will strip. Boyce activated carbon is routinely stripped to 20-30 gm/ton in several operating plants. Thus Boyce activatedcarbon meets all the requirements for gold recovery services.
 The product is applied in CIP process and heap leaching by gold extraction and the precious metals extraction, separation of metallurgical industry. It is used the high-quality coconut shell from Hainan as raw material. It is refined by the high temperature steam activation. It has the advantages such as developed pore structure, high specific, surface area, strong adsorption capability, high wear-resistance, and high decolorizing purity, renew ability etc
 Boyce would like to prove how to increase your gold yield, and consequently your profits, using a granular activated carbon, or an extruded activated carbon. The granular activated carbon are premium coconut shell-based carbons that are among the best available and have been specially pre-treated to reduce platelet content and initial wear of the carbon, which gives you more carbon for your money. The extruded activated carbon was specifically developed by Boyce to reduce the amount of gold lost during the gold recovery process. It improves plant performance, significantly reducing gold losses to the tailings.
 Boyce activated carbon is known for its features of hardness, free of platelets, large pore volume, rapid adsorption and max gold loading, this range exhibits the following advantages: • Low attrition values • Large pores value with selected pore size • Suitable for “carbon in leach”(CIL) and “carbon in pulp” (CIP) process • Available in granular form
