ABSTRACT OF THE DISCLOSURE An improved process for hydrocracking petroleum residuals wherein total conversion and the yield of lower boiling range products are increased. The hydrocracking is accomplished in the presence of a hydrogen donor solvent comprising substantially all of the liquid product having an initial boiling point substantially equal to the final boiling point of the liquid product recovered from the hydrocracked product and, generally, within the range from about 600°F to about 750°F and molecular hydrogen. The conversion is accomplished at a pressure within the range from about 1500 to about 2500 psig and at a temperature within the range from about 800 to about 880°F. Operation at these conditions is essential to achieving the increased conversion and the increased yield of lower boiling liquid products.
