Abstract: A de-hydrogenation catalyst and its use in dehydrogenation of hydrocarbons. The catalyst has low cracking activity and comprises gallium or gallium and platinum on an essentially non-acidic and amorphous alumina-phosphate or silica-alumina-phosphate support with an empirical chemical composition of [Al2O3][SiO2]Y[P2O5]Z, wherein Y is between 0 and 0.2 and Z is between 0.01 and 1.1, with a BET surface area above 50 m2/g, as measured by N2 adsorption experiment.

Abstract: A process is provided for dehydrogenating a paraffinic hydrocarbon comprising sending the paraffinic hydrocarbon to a fluidized bed reactor to be contacted at dehydrogenation reaction conditions with a catalyst composition comprising less than about 0.0999 wt % platinum and about 0.05-2.5 wt % Group I or Group II elements or a mixture thereof. The catalytic composition is prepared without addition of tin, gallium, indium, germanium or lead.
