Only 10 grams of activated carbon granules is needed to completely cover the bottoms of 8 Olympic swimming pools. Due to the highly porous structure, activated carbon can cover an internal surface of 500 to 1,500&nbsp;m<sup>2<\/sup>&nbsp;per gram, and is extremely suitable for removing contaminants from biogas.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">Activated carbon is widely used in the biogas&nbsp;industry to remove pollutants such as siloxanes, hydrogen sulfide (H<sub>2<\/sub>S), and various volatile organic compounds (such as limonene)&nbsp;.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">The conversion of biogas into electricity, heat from renewable energy sources, or biomethane (RNG, renewable natural gas) requires first treating the gas. This will prevent problems with gas engines and allow natural gas quality to exceed 99% CH<sub>4<\/sub>, making it suitable for delivery to the natural gas pipeline network.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">The components that usually need to be eliminated include H<sub>2<\/sub>S&nbsp;(hydrogen sulfide) and siloxanes from landfill gases, or H<sub>2<\/sub>S&nbsp;and terpenes from fermentation gases.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">Activated carbon filtration is widely used in the biogas industry to remove contaminants such as siloxanes ,hydrogen sulfide (H<sub>2<\/sub>S) and VOCS ,as well as various volatile organic compounds such as limonene.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">To ensure consistent performance of commonly used machinery such as internal combustion engines, boilers, and gas turbines, it is necessary to remove siloxanes from biogas. In addition to imbalances, dirt, and other issues, deposits of silica or silicates can also cause wear and tear on these machines.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><strong><span style=\"color: #181818;\">But first of all: what exactly is siloxane?<\/span><\/strong><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">Siloxane is a compound found in cosmetics, deodorants, waterproof windshield coatings, food additives, and some soap products. They are commonly used for smoothing or softening cosmetics, or as chemical structural units for silicone rubber and oil. The well-known application of siloxane is undoubtedly the so-called \"siloxane sealant\". This is a water-based sprayable liquid commonly used for waterproofing concrete or brick walls.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">Siloxane is any compound composed of units in the form of R<sub>2<\/sub>SiO (R=H or HC groups).Organosilicon is a large molecule containing alternating polymer main chains of silicon and oxygen atoms, with organic side groups such as methyl, phenyl, or vinyl groups attached to silicon. The term siloxane comes from silicon, oxygen, and alkanes. Siloxanes are volatile liquid compounds that often persist in their environment.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><strong><span style=\"color: #181818;\">Siloxane removal: Why and how to remove it?<\/span><\/strong><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">Biogas and landfill gas may contain one or more siloxanes, depending on the organic raw materials used to produce biogas in anaerobic digesters or dumped in landfills. When biogas containing siloxanes is burned in gas turbines, boilers, or internal combustion engines, deposits of solid silica (SiO<sub>2<\/sub>) or silicates (Si<sub>x<\/sub>O<sub>y<\/sub>) will adhere to the surface of cylinder heads, pistons, turbine blades, and heat exchangers, causing wear, imbalance, scaling, and other serious problems. In internal combustion engines, deposits on the piston and cylinder head have extremely strong wear and tear, and even a small amount can cause a decrease in engine power (10-20%), an increase in oil change frequency by two times, and can also damage the engine, potentially leading to engine failure.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\"><img src=\"https:\/\/oss.matchpages.cn\/matchpages\/common\/2024\/0103\/8144\/659516fb8b173\/%E5%9B%BE%E7%89%876.webp\" alt=\"activated carbon for Siloxane removal \" data-resolution=\"666*339\" \/><\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">Different types of activated carbon can remove hydrogen sulfide and mercaptan from the gas. It is difficult to choose the most suitable process and related types of activated carbon, and it depends on the chemical composition of the gas as well as physical parameters such as humidity and temperature.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">Volatile Organic Compounds (VOCs) are one of the greatest hazards to workers in the gas and oil industry. Comprised of toxic chemicals such as benzene and toluene, these airborne contaminants can have long-lasting negative consequences on your workers. Repeated exposure to these compounds can result in gastrointestinal disorders, respiratory illness, cancer, and even death. The&nbsp;removal of VOCs&nbsp;from your worksite is of the utmost importance to ensure employee safety, cut maintenance costs, and adhere to regulatory standards.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">There are three primary formulas of bulk activated carbon to choose from when looking for a filter to aid in the removal of VOCs: wood, coconut, and charcoal. With its larger pore size, wood-based carbon is a fine choice when your particulates are also of a larger diameter. However, because it contains only macro-pores, its utilization is limited. Charcoal-based bulk activated carbon is another good choice for the removal of VOCs, but again, it has its limitations. Its pore size is smaller than the wood-based carbon's pore size, plus it has the added benefit of being harder and more durable. Coconut-based bulk activated carbon is unquestionably one of the most superior types of activated carbon for successful removal of VOCs from the air. With almost 90% of its surface area comprised of micro-pores the same size of the molecules you're trying to remove, it's easily renewed and affordable, making it an excellent choice for your application.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">We would like to introduce ACC whole series of biogas activated carbon , ACC biogas activated carbon separates impurities such as hydrogen sulphide (H\u2082S), siloxane, volatile organic compounds (VOCs) and nitrogen from Biogas and well meets user needs in a comprehensive phased approach.<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">ACC activated carbon for Biogas &nbsp;including 3 series as belows :<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">1.<a href=\"activated-carbon-for-rng-and-biogas\" data-page_id=\"19572\" data-page_name=\"Activated Carbon for RNG\/Biogas\uff5cACC\" data-page_type=\"menuPage\"><span style=\"text-decoration: underline;\"><strong><span style=\"color: #2dc26b; text-decoration: underline;\">DS Series for H\u2082S Removal<\/span><\/strong><\/span><\/a> :<\/span><\/p>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">As we knowed that H\u2082S contained in the biogas will corrode the equipments.

<p style="line-height: 1.75;"><span style="color: #181818;"><strong>Why is activated carbon the preferred technology for biogas?</strong> Among any material known to humans, activated carbon has the strongest physical adsorption force or the largest adsorption pore volume. Its surface area can be greater than 1000 square meters/gram, which means that the surface area of 3 grams of activated carbon is equivalent to the surface area of a football field. This makes it an excellent treatment solution for upgrading biogas and biomethane. The use of chemically impregnated activated carbon can further enhance the removal ability of specific pollutants. </span></p>
<p style="line-height: 1.75;"><span style="color: #181818;"><img src="https://oss.matchpages.cn/matchpages/common/2024/0103/1017/659516fba2797/%E5%9B%BE%E7%89%875.webp" alt="activated carbon for biogas " data-resolution="488*336" /></span></p>
<p style="line-height: 1.75;"><span style="color: #181818;">What do Olympic swimming pools, biogas activated carbon and biomethane have in common? Only 10 grams of activated carbon granules is needed to completely cover the bottoms of 8 Olympic swimming pools. Due to the highly porous structure, activated carbon can cover an internal surface of 500 to 1,500 m<sup>2</sup> per gram, and is extremely suitable for removing contaminants from biogas.</span></p>
<p style="line-height: 1.75;"><span style="color: #181818;">Activated carbon is widely used in the biogas industry to remove pollutants such as siloxanes, hydrogen sulfide (H<sub>2</sub>S), and various volatile organic compounds (such as limonene) .</span></p>
<p style="line-height: 1.75;"><span style="color: #181818;">The conversion of biogas into electricity, heat from renewable energy sources, or biomethane (RNG, renewable natural gas) requires first treating the gas. This will prevent problems with gas engines and allow natural gas quality to exceed 99% CH<sub>4</sub>, making it suitable for delivery to the natural gas pipeline network.</span></p>
<p style="line-height: 1.75;"><span style="color: #181818;">The components that usually need to be eliminated include H<sub>2</sub>S (hydrogen sulfide) and siloxanes from landfill gases, or H<sub>2</sub>S and terpenes from fermentation gases.</span></p>
<p style="line-height: 1.75;"><span style="color: #181818;">Activated carbon filtration is widely used in the biogas industry to remove contaminants such as siloxanes ,hydrogen sulfide (H<sub>2</sub>S) and VOCS ,as well as various volatile organic compounds such as limonene.</span></p>
<p style="line-height: 1.75;"><span style="color: #181818;">To ensure consistent performance of commonly used machinery such as internal combustion engines, boilers, and gas turbines, it is necessary to remove siloxanes from biogas. In addition to imbalances, dirt, and other issues, deposits of silica or silicates can also cause wear and tear on these machines.</span></p>
<p style="line-height: 1.75;"><strong><span style="color: #181818;">But first of all: what exactly is siloxane?</span></strong></p>
<p style="line-height: 1.75;"><span style="color: #181818;">Siloxane is a compound found in cosmetics, deodorants, waterproof windshield coatings, food additives, and some soap products. They are commonly used for smoothing or softening cosmetics, or as chemical structural units for silicone rubber and oil. The well-known application of siloxane is undoubtedly the so-called "siloxane sealant". This is a water-based sprayable liquid commonly used for waterproofing concrete or brick walls.</span></p>
<p style="line-height: 1.75;"><span style="color: #181818;">Siloxane is any compound composed of units in the form of R<sub>2</sub>SiO (R=H or HC groups).Organosilicon is a large molecule containing alternating polymer main chains of silicon and oxygen atoms, with organic side groups such as methyl, phenyl, or vinyl groups attached to silicon. The term siloxane comes from silicon, oxygen, and alkanes. Siloxanes are volatile liquid compounds that often persist in their environment.</span></p>
<p style="line-height: 1.75;"><strong><span style="color: #181818;">Siloxane removal: Why and how to remove it?</span></strong></p>
<p style="line-height: 1.75;"><span style="color: #181818;">Biogas and landfill gas may contain one or more siloxanes, depending on the organic raw materials used to produce biogas in anaerobic digesters or dumped in landfills. When biogas containing siloxanes is burned in gas turbines, boilers, or internal combustion engines, deposits of solid silica (SiO<sub>2</sub>) or silicates (Si<sub>x</sub>O<sub>y</sub>) will adhere to the surface of cylinder heads, pistons, turbine blades, and heat exchangers, causing wear, imbalance, scaling, and other serious problems. In internal combustion engines, deposits on the piston and cylinder head have extremely strong wear and tear, and even a small amount can cause a decrease in engine power (10-20%), an increase in oil change frequency by two times, and can also damage the engine, potentially leading to engine failure.</span></p>
<p style="line-height: 1.75;"><span style="color: #181818;"><img src="https://oss.matchpages.cn/matchpages/common/2024/0103/8144/659516fb8b173/%E5%9B%BE%E7%89%876.webp" alt="activated carbon for Siloxane removal " data-resolution="666*339" /></span></p>
<p style="line-height: 1.75;"><span style="color: #181818;">Different types of activated carbon can remove hydrogen sulfide and mercaptan from the gas. It is difficult to choose the most suitable process and related types of activated carbon, and it depends on the chemical composition of the gas as well as physical parameters such as humidity and temperature.</span></p>
<p style="line-height: 1.75;"><span style="color: #181818;">Volatile Organic Compounds (VOCs) are one of the greatest hazards to workers in the gas and oil industry. Comprised of toxic chemicals such as benzene and toluene, these airborne contaminants can have long-lasting negative consequences on your workers. Repeated exposure to these compounds can result in gastrointestinal disorders, respiratory illness, cancer, and even death. The removal of VOCs from your worksite is of the utmost importance to ensure employee safety, cut maintenance costs, and adhere to regulatory standards.</span></p>
<p style="line-height: 1.75;"><span style="color: #181818;">There are three primary formulas of bulk activated carbon to choose from when looking for a filter to aid in the removal of VOCs: wood, coconut, and charcoal. With its larger pore size, wood-based carbon is a fine choice when your particulates are also of a larger diameter. However, because it contains only macro-pores, its utilization is limited. Charcoal-based bulk activated carbon is another good choice for the removal of VOCs, but again, it has its limitations. Its pore size is smaller than the wood-based carbon's pore size, plus it has the added benefit of being harder and more durable. Coconut-based bulk activated carbon is unquestionably one of the most superior types of activated carbon for successful removal of VOCs from the air. With almost 90% of its surface area comprised of micro-pores the same size of the molecules you're trying to remove, it's easily renewed and affordable, making it an excellent choice for your application.</span></p>
<p style="line-height: 1.75;"><span style="color: #181818;">We would like to introduce ACC whole series of biogas activated carbon , ACC biogas activated carbon separates impurities such as hydrogen sulphide (H₂S), siloxane, volatile organic compounds (VOCs) and nitrogen from Biogas and well meets user needs in a comprehensive phased approach.</span></p>
