PURPOSE:To remove efficiently H2S and COS contained in a gas, by bringing an inert gas or a reducing gas contg. no oxygen into contact with activated carbon contg. a specified metallic compd.. CONSTITUTION:An inert gas or a reducing gas contg. substantially no oxygen but contg. H2S or COS, such as beverage carbon dioxide, coke oven gas. blast furnace gas, converter gas, cracked petroleum gas, or natural gas, is brought into contact with activated carbon contg. a specified metallic compd. to remove H2S and COS by adsorption. As the specified metallic compd. in this case, sulfate, nitrate, or the like of copper; and carbonate, nitrate, borate, or the like of Li, Na, K, R6, Ca, or the like; and carbonate, sulfate, nitrate, halide, oxide, or the like of at least one of Al, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, Cd, and Pb are used. |
