Abstract:
A method for the dehydrogenation of n-butane to butenes comprising contacting a feedstock containing n-butane under reaction conditions suitable for the conversion of n-butane to butenes in the presence of a catalyst composition prepared according to the method comprising:(A) impregnating alumina with a tin compound to provide alumina impregnated with tin;(B) subsequently steam treating the alumina impregnated with tin at an elevated temperature to provide a steam treated tin-aluminate;(C) impregnating the steam treated tin-aluminate with a platinum compound to provide a platinum containing tin-aluminate and(D) treating the platinum impregnated tin-aluminate in air at a calcining temperature to provide a calcined platinum containing tin-aluminate.
