METHOD FOR SEPARATING HYDROGEN SULFIDE

摘要

PROBLEM TO BE SOLVED: To provide a method for separating hydrogen sulfide using a zeolite membrane composite which has high throughput and separation performance of hydrogen sulfide and excellent characteristics in separating a gas mixture composed of a plurality of components containing organic matter.SOLUTION: There is provided a method for separating hydrogen sulfide from a gas mixture composed of a plurality of components containing hydrogen sulfide and organic matter using a zeolite membrane, where the zeolite membrane includes a zeolite structure having an 8-membered oxygen ring and is formed on a porous support. Methane is contained as the organic matter and the zeolite having an 8-membered oxygen ring is preferably CHA-type aluminosilicate.
