Abstract
A process and catalyst is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products using multifunctional catalysts. Multifunctional catalysts enable use of less expensive metal by substituting expensive metals for less expensive metals with no loss or superior performance in slurry hydrocracking. Less available and expensive ISM can be replaced effectively.

A process for converting heavy hydrocarbon feed into lighter hydrocarbon products comprising:
- mixing said heavy hydrocarbon feed with catalyst and hydrogen to form a heavy hydrocarbon slurry comprising hydrocarbon liquid and catalyst particles, said catalyst comprising oil-soluble molybdenum and carbon particles comprising pore volume of at least 0.2 cc/g, and a mean diameter of no more than 800 microns, wherein said oil-soluble molybdenum and said carbon particles are added separately to said heavy hydrocarbon liquid feed;
- hydrocracking hydrocarbons in said heavy hydrocarbon slurry in the presence of hydrogen and catalyst in a hydrocracking reactor to produce a hydrocracked slurry product comprising lighter hydrocarbon products;
- and
- withdrawing said hydrocracked slurry product from said hydrocracking reactor.
A process for converting heavy hydrocarbon feed into lighter hydrocarbon products comprising:
- mixing said heavy hydrocarbon feed with catalyst and hydrogen to form a heavy hydrocarbon slurry comprising hydrocarbon liquid and catalyst particles, said catalyst comprising molybdenum in a concentration of no more than about 200 wppm in the feed and carbon particles comprising pore volume of at least 0.2 cc/g, and a mean diameter of no more than 800 microns, wherein said oil-soluble molybdenum and said carbon particles are added separately to said heavy hydrocarbon liquid feed;
- hydrocracking hydrocarbons in said heavy hydrocarbon slurry in the presence of hydrogen and catalyst in a hydrocracking reactor to produce a hydrocracked slurry product comprising lighter hydrocarbon products;
- and
- withdrawing said hydrocracked slurry product from said hydrocracking reactor.
