Ru-Catalyzed Polyethylene Hydrogenolysis under Quasi-Supercritical Conditions.

ABSTRACT: Ru/C-catalyzed polyethylene (PE) and hydrocarbon hydrogenolysis under quasi-supercritical fluid of isopentane was kinetically and mechanistically investigated. PE hydrogenolysis with C-C and C-H cleavage showed zeroth order, suggesting strong adsorption of hydrocarbons. PE yielded broad product distribution of heavy (C_21-40) and diesel-range (C_11-20) hydrocarbons in the primary step of hydrogenolysis due to stochastic C-C cleavage over Ru surface. Catalytic hydrogenolysis of n-hexadecane, squalane, and light hydrocarbons such as n-pentane, iso-pentane, and n-hexane further described C-C cleavage reactivity between primary and secondary carbons, i.e., ¹C-²C and ²C-²C, which has an order of magnitude highe
