A CATALYST SYSTEM FOR COMBINING HYDROTREATING AND HYDROCRACKING AND A PROCESS FOR UPGRADING HYDROCARBONACEOUS FEEDSTOCKS

摘要

physically mixed calyseur system comprising two distinctly different catalytic particles, the first catalyst is a hydrodenitrogenation and / or hydrodesulfurization, and the second is a relatively active hydrocracking catalyst, the particle catlytiques two catalytic components being substantially the same dimensions, in other words, the effective diameter of the particles of each component being substantially identical. The catalyst system of the present invention may be laminated with unmixed catalysts. It has been shown that the new systems of the invention have a surprisingly high selectivity compared to liquid products, and a good stability against contamination when used for hydrotreating and hydrocracking applications combined, and can be used as a stable catalyst system for obtaining an even distribution of heat and control the conditions in the reactor.
