Sulfur Removal Adsorbents for Biogas AxTrap™ 4000 Series: The best value on the market
Hydrogen sulfide (H2S) and light mercaptans are common contaminants that must be removed from various gases such as biogas and landfill-derived methane in particular. Such sulfur species are extremely corrosive and must be removed to meet fuel gas specifications, pipeline specifications and air quality regulations.

Axens offers the AxTrap™ 4000 Series of dry, granular media scavengers to safely and effectively remove these common sulfur contaminants.
AxTrap™ 4000 Series products are based on patented, proprietary mixtures of iron oxides and/or mixed metal oxides - on an inert, inorganic carrier. The result is a particularly robust, granular material in which the metal oxide matrix provides a firmly bound active phase which is non-toxic, non-hazardous, non-pyrophoric and environmentally safe in both fresh and spent condition.
The simplicity of the AxTrap™ 4000 Series is ideal for a wide range of applications, as it is well-suited to the water saturated conditions typical of biogas, landfill and digester gas. AxTrap™ 4000 Series scavengers are effective in anaerobic conditions and achieve very high sulfur loadings when sufficient oxygen is present.
