MIDDLE DISTILLATE HYDROCRACKING CATALYST WITH A BASE EXTRUDATE HAVING A HIGH TOTAL NANOPORE VOLUME

摘要

The present invention is directed to an improved hydrocracking catalyst containing a amorphous silica-alumina (ASA) base and alumina support. The ASA base is characterized as having a high nanopore volume and low particle density. The alumina support is characterized as having a high total nanopore volume. Hydrocracking catalysts employing the combination high nanopore volume ASA base and alumina support exhibit improved hydrogen efficiency, and greater product yield and quality, as compared to hydrocracking catalysts containing conventional ASA base and alumina components.
