Abstract
Methods for hydrocracking a hydrocarbon feed may include contacting an initial catalyst with a conditioning stream having from 50 ppmw to 5000 ppmw heavy polynuclear aromatic compounds to form a conditioned catalyst. The initial catalyst may include a zeolite, an amorphous silica-alumina, or both. The method includes contacting the conditioned catalyst with the hydrocarbon feed in the presence of hydrogen to crack all or a portion of the hydrocarbon feed to form a hydrocarbon product. The hydrocarbon feed has an initial boiling point greater than or equal to 325° C.

A method for hydrocracking a hydrocarbon feed, the method comprising:
- contacting an initial catalyst with a conditioning stream comprising from 50 ppmw to 5000 ppmw heavy polynuclear aromatic compounds to form a conditioned catalyst, wherein the initial catalyst comprises a zeolite, an amorphous silica-alumina, or both;
- and
- contacting the conditioned catalyst with the hydrocarbon feed in the presence of hydrogen to crack all or a portion of the hydrocarbon feed to form a hydrocarbon product, wherein the hydrocarbon feed has an initial boiling point greater than or equal to 325° C.
