| Abstract: | Micro-spheres(20-150μm) with a sufficient amount of Y zeolite synthesized by in-situ crystallization technique from kaolin clay are the important micro-sphere-precursor for obtaining excellent FCC catalyst.In this paper,the impacts of in-situ crystallization steps,composition and preparation techniques of initiators,composition of the crystallizing reaction systems and other aspects over the properties of the catalysts from micro-sphere-precursor have been reviewed.Recent progress in the in-situ crystallizing technique has also been discussed.Combined with the results obtained in our laboratory,the problems and prospect of the in-situ crystallizing techniques for preparing micro-sphere-precursor are given. |
