Abstract
An improved process for hydroconverting carbonaceous material wherein the hydroconversion is accomplished in the presence of a sulfide of tin or tin and at least one metal selected from the Group of metals consisting of the Groups IV-B, V-A, VI-A, VII-A and Group VIII-A metals of the Periodic Table of the Elements and in the presence of iodine. The tin and any other metal may be added directly as the sulfide or as a soluble precursor that will either decompose or be converted to the sulfide. The iodine may be added directly as iodine, hydrogen iodine or as a precursor which will decompose to yield either iodine or hydrogen iodide. The hydroconversion is also accomplished in the presence of hydrogen. The tin sulfide when used either alone or in combination with a sulfide of at least one other metal selected from the Group of metals consisting of Groups IV-B, V-A, VI-A, VII-A and VIII-A of the Periodic Table of the Elements when used with iodine surprisingly increases the yield of gasoline boiling range product from the hydroconversion or liquefaction process. When tin sulfide is used in combination with at least one other metal sulfide, the increase in the yield of gasoline boiling …
