| 摘 要： | 目的制备一种低堆密度高强度的Claus尾气加氢水解催化剂,以解决尾气加氢水解催化剂堆密度高所造成的成本高的问题。 方法考查对氧化铝粉体和载体性能影响最大的焙烧过程,采用TG、SEM、XRD等表征手段,研究低堆密度克劳斯尾气加氢水解催化剂的制备方法,筛选出最优控制条件,提升催化剂综合性能。 结果所制备的三叶草形催化剂堆密度仅为0.50 g/cm3,载体强度达到189 N/cm,比表面积达到312 m2/g。 结论通过浸渍法制备的低堆密度催化剂显示出良好的尾气加氢水解性能,可大大降低催化剂装填成本。

| Abstract: | Objective A Claus tail gas hydrogenation hydrolysis catalyst with low bulk density and high strength was prepared to solve the problem of high cost caused by high bulk density of the catalyst. MethodsThe alumina powder properties and calcination process which has the greatest influence on the performance of the support were investigated. TG, SEM, XRD and other characterization methods were used to study the preparation method of low bulk density Claus tail gas hydrogenation hydrolysis catalyst, and the optimal control conditions were selected to improve the comprehensive performance of the catalyst. ResultsA clover shaped catalyst carrier with bulk density of only 0.5 g/cm3, strength of 189 N/cm and specific surface area of 312 m2/g was prepared. ConclusionThe low bulk density catalyst prepared by impregnation method showed good tail gas hydrogenation hydrolysis performance and greatly reduced the catalyst loading cost. |
