Abstract
The present invention relates to a catalyst having improved selectivity and reactivity and applied to preparing olefins by dehydrogenating C9 to C13 paraffin, and particularly to a technique for preparing a catalyst, which uses a heat-treated support having controlled pores, and most of metal components contained therein are distributed evenly in a support in the form of an alloy rather than in the form of each separate metal, thereby exhibiting high a conversion rate and selectivity when used in dehydrogenation.
Claims7
A dehydrogenation catalyst for use in dehydrogenation of a hydrocarbon gas containing 9 to 13 carbon atoms, configured such that platinum, tin, and an alkali metal are supported to an alumina having controlled pores, wherein the platinum and the tin are in the form of an alloy at a consistent platinum/tin molar ratio at a thickness in an egg-shell shape from the outer surface of the alumina from 110 μm to 250 μm, and wherein the alkali metal is uniformly distributed within the alumina.
