1 前言 羰基硫广泛存在于各种化工原料气中,微量羰基硫的存在会影响多种高效催化剂的使用,在合成氨工业中它是甲醇、甲烷化、氨合成等催化剂失活的最常见的原因。开发羰基硫水解催化剂愈来愈引起人们的重视,其本征动力学研究已有研究,对有较多水汽和二氧化碳存在下的工况条件的 1 Introduction Carbonyl sulfide exists widely in a variety of chemical raw gas, the presence of trace amounts of carbonyl sulfide will affect the use of a variety of efficient catalysts in the ammonia industry it is methanol, methanation, ammonia synthesis catalyst deactivation of the most common causes . Development of carbonyl sulfide hydrolysis catalyst attracts more and more attention, its intrinsic kinetic studies have been studied, for more water vapor and carbon dioxide in the presence of working conditions
