    Abstract: This invention comprises the novel composition formed by mixing (A) a chromium tris-diorgano-orthophosphate of the general formula Cr(OP (O) (OR)2)3 wherein R can be an alkyl, alkoxyalkyl or cycloalkyl group of one to about eight carbon atoms and the chlorinated and brominated derivatives thereof, (B) an alkyl aluminum compound of the general formula R''2R''''Al in which each R'' and R'''' can be an alkyl group of 1 to 6 carbon atoms and each R'''' can also be a hydrogen atom, and (C) a halogenated olefin of four to about eight carbon atoms containing at least four halogen atoms at least two of which are attached to doubly bonded carbon atoms. This invention also comprises the use of this novel combination as a catalyst for the polymerization of ethylene alone or with propylene and other olefins. This invention also comprises the polymer products prepared by said method.

    Abstract: A hydrocracking process wherein heavy hydrocarbon oils having from about 10 to 50 percent boiling above 1,000*F. and containing appreciable amounts of sulfur, nitrogen, and metal-containing compounds as well as asphaltenes are converted into a minor fraction of low sulfur residual fuel oil and a major fraction of low sulfur gasoline. The process comprises hydrocracking the heavy oil with molecular hydrogen, at a temperature of about 700*-850*F. in the presence of a sulfur and nitrogen resistant hydrocracking catalyst comprising a hydrogenating component supported upon an amorphous inorganic oxide cracking base to convert the heavy hydrocarbon oil into a gas-oil fraction and a low sulfur residual fraction; separating the gas-oil fraction from the residual fraction; hydrocracking the gas-oil fraction with molecular hydrogen, at a temperature of 700*-780*F., in the presence of a sulfur and nitrogen resistant hydrocracking catalyst comprising a hydrogenation component supported upon a cation exchanged crystalline silica-alumina zeolitic molecular sieve cracking base to yield low sulfur, low nitrogen gasoline.
