ABSTRACT:
A process for producing lower molecular weight products from a heavy hydrocarbon feedstock is provided wherein the feedstock is contacted with a molten catalyst system comprising a tetrachloroaluminate catalyst and about 1 to about 25 mole percent water. The reaction is carried out at a pressure of from about atmospheric to about 14,200 kPa and a temperature of from about 350.degree. C. to about 550.degree. C. resulting in increased yields of the lower molecular weight liquid products and lower levels of catalyst residue.
