SDT-DS604 Ambient carbonyl sulfur hydrolysis catalyst for propylene

SDT-DS604 COS hydrolysis catalyst for propylene at room temperature is a catalyst made by using a special carrier and loading complex alkali metal additives through a special processing technology. It converts COS in propylene raw materials into H2S at room temperature and then removes H2S with a desulfurizer to achieve fine desulfurization of the raw materials. SDT-DS604 COS hydrolysis catalyst for propylene at room temperature has the characteristics of strong specificity, high COS conversion rate and long service life. It is an excellent catalyst for removing COS from propylene materials at room temperature.
