Novel sorbents (MBS) have been developed for removing CO2, H2S and COS, which were prepared by loading a CO2/H2S-philic polymer, such as polyethylenimine (PEI), on the nanoporous materials. On the basis of their exceptional function, an innovative two-stage process for removing CO2 and H2S, respectively, from biogas, landfill gas and other gas streams was proposed and conducted in a bench-scale apparatus. The developed sorbents and process exhibit some potential advantages: 1) able to remove H2S and COS in the gas to at least less than 60 ppbv, 2) higher sorption capacity and selectivity for CO2, H2S and COS, 3) higher sorption-desorption rate, 4) working at mild conditions, 5) easier for regeneration, and 6) able to remove and recover CO2 and H2S, respectively.
