Abstract
This invention relates to a process for converting a carbonaceous material to a liquid product using a hydrogen donor solvent. More specifically, this invention relates to a process for hydroconverting carbonaceous material in which a 400.degree.-1000.degree. F. hydroconversion product fraction is further hydrocracked and a hydrocracked fraction is used as the hydrogen donor solvent. An increased quantity of liquid product is achieved by removing an ash residuum from the hydroconversion product fraction prior to the hydrocracking process.
Claims9
A process for hydroconverting a carbonaceous material comprising
- forming a mixture of carbonaceous material and hydrogen donor solvent;
- reacting the mixture in the presence of a hydrogen containing gas, under hydroconversion conditions, to form a hydroconversion product stream;
- separating a liquid fraction of the hydroconversion product stream, wherein the liquid fraction has an initial boiling point of about 350.degree. F., into a clarified fraction and ash residuum;
- and
- hydrocracking the clarified fraction in the presence of hydrogen and a catalyst consisting of an activated metal prepared from an oil soluble or oil dispersible metal compound, under hydrocracking conditions, wherein the metal has a concentration of about 2-20 wt % on the basis of the clarified fraction being hydrocracked, and is selected from the group consisting of Groups II, III, IV, V, VIB, VIIB and VIII of the Periodic Table of Elements, to form a hydrocarbon product stream.
