Abstract: NORBORNENE AND ALKYL SUBSTITUTED NORBORNENES ARE MADE BY CONDENSING OLEFINS SUCH AS ETHYLENE, PROPYLENE, ETC. WITH DICYCLOPENTADIENE IN THE VAPOR PHASE IN A PRESSURIZED REACTOR. THE USE OF A SUBSTANTIAL EXCESS OF OLEFIN AND THE USE OF CONDITIONS USCH THAT THE PRODUCTS AND THE REACTANTS ARE IN THE VAPOR PHASE SUBSTANTIALLY ELIMINATES BY-PRODUCTS.

Abstract: Process for the hydrogenation of heavy hydrocarbon residues boiling in the range from about 220* F to about 650*F and containing up to 10 percent by weight of tars and gums wherein the hydrocarbon is mixed with hydrogen, passed through a hydrogenation zone under a pressure of 100-1,000 psig, a temperature of 100*C to 200*C, and in the presence of a supported platinum or palladium catalyst and cooled. The hydrogenated product is then distilled to produce a high grade gasoline blend stock as the overhead and the bottoms are useful as a fuel oil.
