ABSTRACT A process for producing lower average molecular weight products from heavy liquid hydrocarbons is pro- vided comprising contacting the feed material in the presence of a co-catalyst system comprising a molten salt of sodium tetrachloroaluminate (NaAlCl4) and hydrogen tetrachloroaluminate (HAlCl4) at a pressure of from about 0.8 to about 140 atm (81 to about 14185 kPa) and a tem- perature of from about 200°C to about 550°C. According to the present invention use of the HAlCl4 as a co-catalyst with NaAlCl4 results in increased yields of lower average molecular weight products and improved levels of denitrogenation and desulfurization. The elements of the co-catalyst system may be prepared separately and mixed.
