- W44265032 abstract "This study on the contact conversion of cyclic hydrocarbons under hydrogen pressure gives grounds for the following conclusions on the characteristics of highly dispersed group VIII metals of the periodic system deposited in low concentrations on aluminum oxide, silica gel, or activated carbon: In addition to the hydrogenation, dehydrogenation, isomerization and hydrogenolysis of the C—C bond these catalysts are also capable of methylating the benzene and penta- and hexamethylene rings by means of methylene radicals arising at their surface at elevated temperatures from disintegration of the cyclanes to methane. With respect to methane forming cleavage of the five-membered ring and its hydrogenolysis to alkanes, Ru-SiO2 proved to be highly active. Ruthenium deposited on aluminum oxide is very active with respect to the isomerization of ethylcyclopentane to 1,2- and 1,3-dimethylcyclopentanes. Rhodium on aluminum oxide is characterized by active isomerization of methylcyclohexane with contraction of the ring to 1,2- and 1,3-dimethylcyclopentanes. It was found that this reaction increases with increasing pressure, other conditions being equal. Highly disperse nickel-alumina catalysts containing 10, 20, and 30% nickel possess a very great ability for hydrogenolysis of the side chains of toluene, ethylbenzene, n- and i-propylbenzenes and n-butylbenzene (30% Ni). In converting six-membered cyclanes (methylcyclohexane, ethylcyclohexane), palladium deposited on alumina revealed a high dehydrogenating activity and stability, practically equaling that of Pt-alumina." @default.
