Annotation:
The process of heptane isomerization as a technique is considered to fulfill the Euro-6 environmental standard for gasoline. The efficiency of isomerization of the C7-hydrocarbon fraction on solid acid catalysts based on zeolites is considered is assessed. A new type of solid-acid catalysts for C7-hydrocarbons isomerization based on newly synthesized inorganic oxocomplexes is proposed. For this purpose, a number of mixed heteropolycomplexes with a modified Keggin structure containing various transition metals (including platinoids) have been synthesized. A technology has been developed for producing deposited super acid catalysts coated by modified Keggin series heteropolycomplexes on various types of carriers.
