Abstract:
A process for dehydrogenating a hydrocarbon feedstock and producing an olefinic product, the process comprising:contacting a hydrocarbon feedstock at dehydrogenation conditions with a dehydrogenation catalyst to produce an olefinic product; the dehydrogenation catalyst comprising about 0.01 to about 5.0 percent of a platinum group metal, about 0.02 weight percent to about 10.0 weight percent of zinc, an alkali metal and a borosilicate molecular sieve; the molecular sieve having been prepared directly in the hydrogen form containing less than about 100 ppm sodium or converted to the hydrogen form containing less than about 100 ppm sodium, thereafter impregnated with the platinum group metal and impregnated with zinc, and subsequently impregnated with the alkali metal; andrecovering the olefinic product.
