Activated Carbon for RNG/Biogas
ACC activated carbon separates impurities such as hydrogen sulphide (H₂S), siloxane, volatile organic compounds (VOCs) and nitrogen from RNG/Biogas.
RNG/biogas is a fast growing industry that requires activated carbon to purify combined heat and power (CHP) and pipeline injection. Methane is increasingly being collected from the anaerobic digestion (AD) of organic waste from agricultural production, municipal water resource recovery facilities (WRRFs) and landfills.
The RNG/biogas is being upgraded to a renewable energy source that can reduce emissions and replace fossil energy sources. In this way, ACC is contributing to build up a clean, healthy and sustainable energy future.
APPLICATIONS
Activated Carbon for RNG/Biogas
DS Series for H₂S Removal
While biogas is used in internal combustion engines, turbines or fuel cells, H₂S contained in the biogas will corrode the equipments. ACarbon DS Series is specifically designed to remove H₂S from biogas streams, effectively providing a high performance, cost effective H₂S removal solution. Produced by a proprietary high temperature steam activation process, it performs well in high H₂S adsorption rate, high loading capacity and long service life.

WEC/BP Series for VOCs Removal
Biogas that derived from landfill gas (LFG) and from agriculture and wastewater treatment facilities is usually heavily contaminated with volatile organic compounds (VOCs). As the market for biogas continues to shift from power generation to renewable natural gas (i.e. biomethane), the removal of halogenated VOCs has become extremely important to biogas upgrading systems and to the effective operation of gas permeation membranes.
ACarbon® WEC series and BP series activated carbons have a well-developed pore structure, high specific surface area, selective adsorption, significant effectiveness in VOCs removal, high adsorption capacity compared to coal-based activated carbons, long service life and low overall cost.
