Abstract
Novel heterogeneous boride catalysts comprising a polyborane anion and a Group VIII metal for the treatment of carbonaceous materials. The catalyst is prepared by the steps of contacting a polyborane anion with a salt of a Group VIII metal in the presence of a solvent to form a catalyst precursor, removing the solvent and, heating the precursor under hydrogen at a pressure of at least about 3.45 MPa at a temperature of from about 200.degree. C. to about 600.degree. C. Treatment of carbonaceous materials includes the steps of contacting the carbonaceous material with the heterogeneous boride catalyst and with hydrogen in the presence of a solvent in a reactor, pressurizing the reactor with hydrogen to at least about 3.45 MPa and, heating the reactor to a temperature of about 200.degree. C. to about 600.degree. C. The heterogeneous boride catalyst can also be prepared in situ.
