HYDROCARBON CONVERSION CATALYST AND PROCESSES FOR THE MANUFACTURE AND USE THEREOF

摘要

Normal paraffins are dehydrogenated to form normal olefins by contacting them at dehydrogenation conditions with a catalytic composite comprising a combination of a platinum group component, a rhenium component and an alkali or alkaline earth component with an alumina carrier material. A specific example of the dehydrogenation method disclosed herein is a dehydrogenation of long-chain normal paraffins with a catalyst comprising a combination of a platinum component, a rhenium component, and an alkali or alkaline earth component with an alumina carrier material in amounts sufficient to result in a catalytic composite containing, on an elemental basis, 0.01 to 1 wt. % platinum, 0.01 to 1 wt. % rhenium, and 0.01 to 5 wt. % of the alkali or alkaline earth metal.
