Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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. 2. The dehydrogenation catalyst of claim 1 , wherein the platinum/tin molar ratio is 2.0-4.0. 3. The dehydrogenation catalyst of claim 1 , wherein the alumina is spherical. 4. The dehydrogenation catalyst of claim 1 , wherein the catalyst is configured such that, based on a total weight of the catalyst, 0.1-1.0 wt % of the platinum, 0.2-4.0 wt % of the tin, and 0.1-3.0 wt % of the alkali metal are supported to the alumina. 5. The dehydrogenation catalyst of claim 1 , wherein the alkali metal is at least one selected from the group consisting of potassium, sodium, and lithium. 6. A method of dehydrogenating a hydrocarbon, comprising bringing a hydrocarbon gas into contact with the catalyst of claim 1 under dehydrogenation conditions. 7. The method of claim 6 , wherein the hydrocarbon gas includes a hydrocarbon gas containing 9 to 13 carbon atoms suitable for dehydrogenation.
