摘要
用微反色谱联用技术及程序升温脱附装置对ＣＳ２水解催化剂进行了活性测试与表面碱分布的研究。结果发现碱性氧化物含量以及第二活性组分的加入对催化剂活性有较大影响，对表面碱分布有着不同的调变作用。在ＣＳ２水解中强碱中心起主要的催化活性中心作用，强碱中心的碱量与１６０℃下的活性有良好的线性关系。
Several kinds of aluminabased catalysts for CS2 hydrolysis were investigated by means of microchromatography The base distribution of these catalysts were determined by the temperature porgrammed desorption technique (TPD) It turned out that active species content and the second active species significantly affected the activities and surface base distribution of catalysts The stronger basic sites play an important role for CS2 hydrolysis Furthermore, there exsited good linear relationship between the basicity of stronger basic sites and the activities at 160℃
