Catalyst composite for dehydrogenation of hydrocarbons and method of preparation thereof

摘要

The present invention provides a dehydrogenation catalyst composite that is capable of providing a dehydrogenated hydrocarbon product characterized by a bromine number of at least 19. for hydrocarbons. The dehydrogenation catalyst of the present invention comprises a nano-sized complex containing a Group VIII component; a group IVA component and a sulfur containing capping agent; an alkali component; a halogen component; and a support with an inner core of alpha alumina and an outer layer comprising a mixture of gamma alumina and delta alumina.
