Major Factors Determining the Activity of Bifunctional Environmentally Safe Catalysts for Hexane Skeleton Isomerisation

A series of environmentally safe highly efficient bifunctional catalysts for hexane skeleton isomerisation was studied. It was demonstrated that the activity of the catalysts is determined mainly by acidic properties. Reaction rate values and selectivity level with respect to target products were determined depending on the concentration of Lewis acid, whereas the content of Bronsted acidic centers was maintained approximately constant. The data obtained could serve as a basis for the development of Russian highly efficient catalysts for light gasoline skeleton isomerisation those could be used for obtaining branched isomers for —5n—8 hydrocarbons with the octane number ranging within 92n105.
