        Fischer process is workable at ordinary pressures because the hydrogenated products are stable at the low temperatures used.  However, the Bergius process requires high pressures owing to the unfavorable position of the equilibria of certain cyclic reaction types at the high temperatures necessary for the destructive hydrogenation.  Lowering the required high pressures should be possible if highly active catalysts can be developed.  This does not hold if aromatic gasolines of high knock rating are to be produced.
