H2S Removal from Biogas

Activated Carbon: The removal of hydrogen sulphide (H2S) from biogas with activated carbon requires a thin water layer in the carbon pore structure to promote the reaction between H2S and the carbon surface. The required relative humidity (RH) is 30%~100%; the optimal relative humidity is 60~70%. For the working is a minimum oxygen concentration 4 x the H2S concentration on molar basis required. The activated charcoal used by GtS is specially developed for H2S removal from biogas.
