ABSTRACT:
A process is provided for the hydrocracking of a hydrocarbon charge stock which comprises reacting the charge stock with hydrogen at hydrocracking conversion conditions in contact with a catalytic composite comprising a combination of a Group VIB metal component, Group VIII metal component, and a fluorine component present in an amount ranging from 1 to 3 wt. %, on an elemental basis, based on the composite, with a silica-thoria carrier material wherein the carrier is cogelled silica-thoria consisting of from about 25% to about 99% by weight silica and from 1% to about 75% by weight thoria.
A hydrocracking catalyst is also provided which comprises a combination of a nickel component, a tungsten component, and a fluorine component with a silica-thoria carrier material. The nickel, tungsten, and fluorine components are present in amounts sufficient to result in the composite containing, on an elemental basis, about 0.5 to about 2 wt. % of the nickel component, about 0.5 to about 14 wt. % of the tungsten component, and about 1 to about 3 wt. % of the fluorine component.
Another hydrocracking catalyst is provided which comprises a silica-thoria-alumina carrier material wherein the carrier material comprises from about 25 to about 99 wt. % silica, from about 1 to about 75 wt. % thoria, and from about 1 to about 25 wt. % alumina.
