A METHOD FOR MANUFACTURING CATALYSTS FROM DEACTIVATED HYDROTREATMENT CATALYSTS AND THE APPLICATION THEREOF IN A DISPERSED-BED HYDROCRACKING PROCESS

摘要

This invention is related to the formulation and method for preparing catalytic materials for hydrocracking (HCK) processes for heavy crude oil fractions in dispersed-bed reactors from catalysts deactivated in fixed-bed hydrotreatment (HDT) units. To prepare said materials, the catalyst precursors must be subjected to a process comprising the following single operations consecutively: washing by liquid/liquid extraction, grinding, drying, calcination and activation by treatment with elemental sulfur. This invention also relates to a hydrocracking process on a modified dispersed bed that improves the performance of the catalysts prepared.
