Review of H2S sorbents at low-temperature desulfurization of biogas

This review surveys the sorbents that remove Hydrogen Sulfide (H2S) from the biogas generated at low-temperature ranges from different sources. Biomass feedstocks contain low percentages of protein-derived sulfur that is converted primarily into H2S, as well as small amounts of carbonyl sulfide (COS...
