Abstract
Abstract A hydrocarbon conversion process is disclosed involving the hydrocracking of a catalytic cycle oil in the presence of a catalyst having a nickel component, a tungsten component, and a support component containing a crystalline molecular sieve material present in an amount ranging from 10 to 40 wt. % based on the weight of the support component with the balance of the support component being alumina.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
154 words
A process for the hydrocracking of a feedstock comprising a light catalytic cycle oil having a boiling range from about 350° F. to about 700° F. which comprises reacting the feedstock with hydrogen at hydrocracking conversion conditions in the presence of a catalyst comprising a hydrogenation component comprising a nickel component and a tungsten component wherein the nickel component is present in an amount ranging from about 1 to about 10 wt. % and the tungsten component is present in an amount ranging from about 10 to about 30 wt. %, both calculated as oxides and based on the total catalyst weight and a support component consisting essentially of a crystalline molecular sieve component and an alumina component wherein the crystalline molelcular sieve component is present in the support in an amount less than about 40 wt. % and greater than about 10 wt. % based on the total weight of the support component.
Claim 2
Dependent Claim
154 words
A process for the hydrocracking of a feedstock comprising a light catalytic cycle oil having a boiling range from about 350° F. to about 700° F. which comprises reacting the feedstock with hydrogen at hydrocracking conversion conditions in the presence of a catalyst comprising a hydrogenation component comprising a nickel component and a tungsten component wherein the nickel component is present in an amount ranging from about 1 to about 10 wt. % and the tungsten component is present in an amount ranging from about 10 to about 30 wt. %, both calculated as oxides and based on the total catalyst weight and a support component consisting essentially of a crystalline molecular sieve component and an alumina component wherein the crystalline molelcular sieve component is present in the support in an amount less than about 40 wt. % and greater than about 10 wt. % based on the total weight of the support component.
