Most natural gas contains small amounts of mercury. Mercury removal is particularly important in the production of liquefied natural gas (LNG), as mercury can lead to corrosion of aluminum heat exchangers during production. The ACarbon HgR series activated carbon uses leading technology for mercury removal from natural gas to accept large amounts of impregnation while maintaining access to complex pore structures for treated gas. After activation, sulfur is distributed in a thin layer over a wide internal surface area of carbon, effectively purifying the gas and removing mercury compounds that damage process equipment.

Activated carbon is used to desulfurize from ethylene, natural gas and biogas. Activated carbon particles can be used to remove H₂S from landfills, anaerobic digester (AD), or municipal wastewater treatment plant (WWTP) biogas streams.

High purity gases are increasingly used in refinery operations. Remote extraction sites often require gas generation on site. Activated carbon plays a key role in separating oxygen, hydrogen, and other critical gases from air in PSA systems. ACC activated carbon products have proven to be ideal adsorbents for this application, with a very high surface area that ensures high adsorption capacity and selective adsorption and desorption under varying pressures.

ACarbon®activated carbon can store methane (the main component in natural gas) at lower storage pressure, thereby reducing the cost of compression and storage container costs, and reducing safety hazards.
