A silica-alumina based composite material for making hydroprocessing catalysts, is disclosed. The silica-alumina composite material generally comprises at least two silica-aluminas, the first being a modified first silica-alumina, and the second being a second silica-alumina that is unmodified or modified. The first silica-alumina is modified to comprise silica and alumina domains and a silica-alumina interphase. The second silica-alumina may also be modified at the same time or separately to comprise silica and alumina domains and a silica-alumina interphase. The first silica-alumina and the second silica-alumina differ in one or more physical and/or chemical characteristics, e.g., the ratio of silica to alumina, surface area, pore size, pore volume, silica domain size, or alumina domain size. The invention can be used for making catalyst base materials and catalysts useful for upgrading hydrocarbon feedstocks to produce fuels, lubricants, chemicals and other hydrocarbonaceous compositions.

A petroleum refining method for upgrading petroleum products improves the efficiency and reduces the costs of upgrading oils, such as lipids, bitumen, crude oil, fracking oils, synthetic oils, and other feeds, to produce useful fuels and chemical precursor streams. Usage of a specific type of zeolite (ZSM-5) catalyst, supercritical water to control coke formation, and a specific response to phase behavior and other catalytic effects optimize the process. A prescribed set of reactor conditions employing supercritical water increases activity of the catalyst in industrial reactions.
