摘　　要：重油催化裂化(RFCC)的核心是要提高原料油的重油转化能力,相应催化剂的研究方向是改善催化剂水热稳定性和孔道贯通性,提高一次裂化能力,减少重油分子在催化剂中的扩散限制。利用天然高岭土族矿物采用原位晶化工艺制备的催化剂具有重油转化能力强,水热稳定性和抗重金属性能突出的优势。介绍了利用天然高岭土族矿物制备的原位晶化型催化剂不同技术路线的研究进展,分析这些技术的优势和不足,最后提出寻找优质高岭土土源、合成纳米分子筛、改进孔道结构和优化活性中心分布是这类催化剂进一步研究发展的方向。The core of RFCC is to improve the heavy oil conversion capacity of feedstock.The research direction of the corresponding catalyst is to improve the hydrothermal stability and pore connectivity of the catalyst,improve the primary cracking capacity,and reduce the diffusion limit of heavy oil molecules in the catalyst.In-situ crystallization of zeolite catalyst from kaolin group minerals has advantages of strong heavy oil conversion ability,hydrothermal stability and heavy metal resistance.In the present study,the research progress of different technical routes of in-situ crystallized catalysts prepared from natural kaolin group minerals is introduced,and the advantages and disadvantages of these technologies are analyzed.Finally,it is proposed that development direction of this type of catalyst is to find high-quality kaolin source,synthesize nano molecular sieve,improve pore structure and optimize active center distribution.
