Abstract
A process for removing hydrogen sulfide (H2S) from a H2S-containing gas composition includes charging a liquid to a reactor under continuous agitation and dispersing particles of a cobalt-based zeolitic imidazolate framework-67 (ZIF-67) in the liquid to form a ZIF-67 mixture. The method further includes introducing the H2S-containing gas composition to the reactor containing the ZIF-67 mixture under continuous agitation and passing the H2S-containing gas composition through the ZIF-67 mixture. In addition, the method includes adsorbing the H2S from the H2S-containing gas composition onto the ZIF-67 to remove the H2S from the H2S-containing gas composition and form a purified gas composition.
