摘要
采用共沉淀法制备了Cu、Mn、Zn和Ni复合的CO氧化脱氧催化剂FS,并将其应用于模拟的环氧丙烷尾气脱氧试验。考察了反应温度、空速、CO与O2的物质的量比、饱和水蒸气、丙烯对催化剂活性的影响。结果发现:纯CO氧化反应的最佳条件为反应温度130℃,空速330 h-1,CO与O2的物质的量比2.3∶1;饱和水蒸气、丙烯可能与反应组分CO、O2在催化剂上产生吸附竞争,占据催化剂的活性中心,从而引起催化剂的活性下降。
A composite deoxidation catalyst FS of Cu, Mn, Zn and Ni for CO oxidation was prepared by coprecipitation method, and was used to the deoxidation experiments of simulated epoxy propane tail gas. The influences of reaction temperature, space velocity, mole ratio of CO to 02, saturated steam and propylene on the activity of the catalyst were investigated. The results showed that the optimal conditions of pure CO oxidation were reaction temperature 1 3 0 ~C , space velocity 3 3 0 h - l , mole ratio of CO to 02 2.3 ： 1. There could be competition in adsorption on the catalyst among saturated steam, propylene and reactant CO and 02. Saturated steam and propylene could occupy some active sites of the catalyst and thus resulted in the decrease of the catalyst activity.
