  • Patent number: 5064527
    Abstract: An improved hydroconversion process for carbonaceous materials wherein a dihydrocarbyl substituted dithiocarbamate of a metal selected from any one of Groups IV-B, V-A, VI-A, VII-B, and VIII-A of the Periodic Table of Elements or a mixture thereof is used as a catalyst precursor. The improved process is effective for both normally solid and normally liquid carbonaceous materials and for carbonaceous materials which are either solid or liquid at the conversion conditions. The hydroconversion will be accomplished at a temperature within the range from about 500.degree. to about 900.degree. F., at a total pressure within the range from about 500 to 7000 psig and at a hydrogen partial pressure within the range from about 400 to about 5000 psig.
