A method for the efficient conversion of heavy oil to distillates using sequential hydrocracking in the presence of both supported and colloidal catalyst immediately followed by a high temperature-short residence time thermal treatment. The hydrocracker reaction products or a heavy oil and hydrogen donor diluent may be advantageously heated by direct contact with high velocity combustion products.
