FIELD: chemistry.
SUBSTANCE: invention relates to a catalyst composition for dehydration of hydrocarbons containing nano-sized complex, containing group VIII element; group IVA element and sulphur-containing protective agent; alkaline element; halogen element selected from a group comprising fluorine, chlorine, bromine and iodine; and a substrate with an inner core of alpha-aluminium oxide and outer layer containing a mixture of gamma-aluminium oxide and delta-aluminium oxide, wherein said substrate has surface area in range of 20–200 m2/g; wherein said catalyst composition is able to provide a dehydrogenated hydrocarbon product, characterised by bromine number of at least 19. Invention also relates to a method of producing a catalyst composition and to a method of dehydrogenating hydrocarbons.
EFFECT: technical result consists in preparing a catalyst with low diffusion resistance and with improved activity.
