Hydrocracking catalysts consisting of metal and microporous molecular sieves
play an essential role in petroleum industry. This review summarizes the compositions,
preparation approaches and applications of hydrocracking catalysts based on molecular
sieves. Specifically, this review includes: (i) a brief overview of selected methods of direct
synthesis and the post-synthetic modification of molecular sieves; (ii) an introduction of the
existing strategies to incorporate metals with microporous molecular sieves to prepare bifunctional
catalysts, e.g., impregnation and ion exchange; and (iii) a summary of various
hydrocracking catalysts for long chain paraffins and aromatics.
Keywords: Bifunctional catalysts, hydrocracking, molecular sieves, post-synthesis modification.
