GAS PURIFICATION BY ADSORPTION OF HYDROGEN SULFIDE

摘要

Hydrogen sulfide is removed from a hydrogen rich gas stream using adsorben ts having a low loss of carbon dioxide adsorption capacity upon sulfur loading including high purity silica gels, titania or highly cross-linked, non-chemically reactive resins. The adsorbents may be used to adsorb both carbon dioxide and hydrogen sulfide, o r may be used as a guard bed upstream of a separate carbon dioxide adsorbent.
