    Abstract: A wax modifying composition comprising the combination of (1) a Friedel-Crafts condensation product of a halogenated paraffin with an aromatic hydrocarbon and (2) an oil soluble copolymer of ethylene and a C3-C30 alpha olefin, or a terpolymer of ethylene with a C3-C30 alpha olefin and a minor amount of a nonconjugated diolefin. The copolymer and terpolymer may be improved by oxidation to form hydroperoxy materials followed by reduction to form reduced oxygenated compounds.

    Abstract: Hydrocarbon residua boiling mostly 1,000* F. and above are catalytically hydrocracked under liquid phase conditions and novel recycle ratios to obtain a product which is predominantly an aromatic gas oil which is eminently suitable either as a solvent or as feed to commercial hydrocracking operations. Although the upper boiling limit of this gas oil may be in the range of 600*-800* F., the process is illustrated with separation into fractions boiling 650* F.- and 650* F.+. An amount of the low-boiling and high-boiling fractions are recycled so that the feed mixture to the reaction zone contains 20 percent of the lowboiling fraction, 40 percent of the high-boiling fraction, and 40 percent of fresh feed while the high-boiling fraction is recycled to extinction at a rate such that the amount present in the feed mixture to the reactor is equal to the amount in the product. 125 percent of an acyclic hydrocarbon modifier is added to the reaction mixture to act as a free radical acceptor under such conditions that is has a residence time of 1 hour or less as compared to 1 to 6 hours for the residua-recycle mixture.
