Abstract

A catalystic composite of a porous carrier material, a nickel component and a metal component selected from Groups I, II or V of the Periodic Table. When utilized in a hydrocracking process, to produce lower-boiling hydrocarbon products, for example gasoline boiling range hydrocarbons, the catalyst effectively inhibits excessive formation of liquefied petroleum gas of the propane/butane type, as well as lighter gaseous hydrocarbons. A preferred catalytic composite comprises a crystalline aluminosilicate, from about 0.1 percent to about 10.0 percent by weight of nickel and from about 0.01 percent to about 2.0 percent by weight of a metallic component selected from vanadium, lithium, beryllium or barium.

Claims

2. The process of claim 1 further characterized in that said hydrocracking conditions include a maximum catalyst temperature of from 600* F. to about 900* F., a pressure of from 1,000 to about 5,000 p.s.i.g., a hydrogen concentration of from 2,000 to about 50,000 s.c.f./Bbl. and an LHSV of from about 0.25 to about 10.0.

3. The process of claim 1 further characteriZed in that said porous carrier material is an amorphous composite of alumina and silica.

4. The process of claim 1 further characterized in that said carrier material is faujasite.

5. The process of claim 1 further characterized in that said catalytic composite comprises a porous carrier material, a nickel component and from 0.01 percent to about 2.0 percent by weight of at least one metallic component.
