ChemInform Abstract: Hydrogenolysis of Saturated Hydrocarbons. Part 5. Influence of Hydrocarbon Structures on the Activity and Selectivity of Ni on Silica.
Abstract
Hydrogenolysis of hexane, 2- and 3-methylpentanes, 2,3- and 2,2-dimethylbutanes, and 2,2,3-trimethylbutane has been investigated on a 20 wt.-"/o Ni/SiO2 catalyst in an attempt to understand the reasons why hydrogenolysis of alkanes leads almost exclusively to successive demethylations.
ChemInform Abstract
Hydrogenolysis of hexane, 2- and 3-methylpentanes, 2,3- and 2,2-dimethylbutanes, and 2,2,3-trimethylbutane has been investigated on a 20 wt.-"/o Ni/SiO2 catalyst in an attempt to understand the reasons why hydrogenolysis of alkanes leads almost exclusively to successive demethylations. However, besides demethylation, multiple hydrogenolysis and hydrogenolysis of internal bonds also occur, to a small extent, depending on the hydrocarbon structure. The activity of the catalyst is influenced little by the hydrocarbon structure especially when there is no quaternary carbon atom in the molecule.
