摘　　要：介绍了高岭石、准埃洛石、埃洛石等三种高岭土与催化性能（如比表面积、孔容、孔径分布、表面酸性、裂解活性等）有关的一些性质的研究结果。在上述研究的基础上，分别以这几种类型的高岭土为填料．以ＣＲＥＹ和ＵＳＹ分子筛为活性组元制备了ＦＣＣ催化剂，考察了填料的物化性质与催化剂性能的关系。试验结果表明，用准埃洛石制备的ＫＹ１；催化剂与用苏机１－Ｂ制备的同类催化剂相比，具有焦炭、汽油选择性好的特点，而以埃洛石为填料制备的ＫＹＺ催化剂，具有强度好、裂解活性高、对重油裂解能力强的特点。Kaolinite, pseudo-halloysite, and halloysite are used as the components of the matrices in FCC catalysts, the properties of which such as surface area, pore volume, pore size distribution, surface acidity, cracking activity, etc. have been studied. Different catalyst samples were prepared by us ing these clays as matrix components and CREY or USY zeolites as active components. The performances of the catalysts were correlated with the physico-chemical properties of the clays. The results indicated that KY1 catalyst using pseudo-halloysite as a matrix component displayed better coke selectivity and gaso line selectivity in cracking reaction compared with the catalyst using Suzhou l-B clay as the matrix compo nent. Meanwhile, KY2 catalyst using halloysite as a matrix component exhibited better attrition resistant ability and resid cracking activity in cracking reaction compared with other catalysts.
