PROCESS FOR THE CATALYTIC HYDROREFINING OF AN ASPHALTENIC HYDROCARBONACEOUS CHARGE STOCK EMPLOYING A CATALYST PROVIDED ON SUPPORT METERIAL HAVING IMPROVED MACROPORE VOLUME

摘要

Hydrorefining of petroleum stocks containing asphaltenes, sulfur and nitrogen with an extruded refractory inorganic oxide catalyst support wherein said support is prepared by admixing a peptizing agent, a surfactant, and a water-insoluble particulate organic polymer having a particle size of from about 1 to about 200 microns with a powdered refractory inorganic oxide and extruding the resulting mixture.
