PAS-10 is a new de-arsenic agent, with metallic oxide as active component and special auxiliaries, which is researched and produced by SJEP. The one-time loading costs can be reduced because of high strength and low bulk density. Moreover it has a high arsenic capacity, high dearsenic precision and a long life span. PAS-10 de-arsenic agent can be used at a high space velocity and high content of arsenic hydride. It is mainly applied for removing arsenic hydride from propylene etc to protect the downstream polymerization catalysts and other deep processing catalysts.
