摘要 复合氧化物催化剂在汽车尾气净化中硫中毒及抗硫中毒机理——ＴＰＤ研究秦正龙杨汉培（徐州师范学院化学系，徐州２２１００９）（清江石油化工厂，淮阴２２３００２）关键词：复合氧化物催化剂汽车尾气净化ＳＯ２中毒１前言传统的汽车催化剂均以贵金属为活性组元，虽然具... Mechanism of SO 2 poisoning of non noble metal catalysts for auto emission control was studied by TPD. The result showed that, besides the formation of SO 2- 4 which had been reported previously, the poisoning mechanism is a complex process. SO 2 is first adsorbed on active sites of catalyst, then, chemical adsorption of SO 2 in part with active components of catalyst had occurred to form sulphite, and sulphate respectively. In comparison with the effect of forming sulphate on deactivation of catalyst, the effect of chemical adsorption of SO 2 and forming sulphite is more important.
