Abstract
Dehydrogenatable hydrocarbons are dehydrogenated by contacting them, under dehydrogenation conditions, with a dehydrogenation catalyst comprising a combination of a catalytically effective amount of an alkali or alkaline earth component with a catalytic composite consisting essentially of a tin component in combination with a platinum component on a carrier material, wherein the catalytic composite is prepared by the method which comprises: (a) impregnating a high surface area porous carrier material with a solution of a complex chlorostannate (II) chloroplatinate anionic species, the solution being stabilized in contact with the carrier material with an aqueous halogen acid; and thereafter, (b) drying and calcining the impregnated carrier material. For the dehydrogenation of normal paraffin hydrocarbons, this dehydrogenation catalyst preferably contains, on an elemental basis, about 0.01 to about 2 wt. % platinum, about 0.01 to about 5 wt. % tin, and about 0.01 to about 5 wt. % alkali or alkaline earth metal.
