Abstract
Official abstract text for this publication.
The present invention relates to a catalyst used in a dehydrogenation reaction of a linear hydrocarbon gas in a range of C3 to C4, and provides a dehydrogenation catalyst which is deposited on a carrier obtained by changing the phase of platinum, an auxiliary metal and an alkali metal, wherein the platinum and the auxiliary metal are present as a single complex within a certain thickness from the outer edges of the catalyst in an alloy form.
First claim
Opening claim text (preview).
The invention claimed is: 1. A dehydrogenation catalyst for use in dehydrogenation of straight-chain hydrocarbon gas in a range of C3 to C4, the dehydrogenation catalyst comprising: platinum, an auxiliary metal, and an alkali metal which are carried in a phase-changed carrier, wherein the platinum and the auxiliary metal form a single complex and are present in an alloy form within a predetermined thickness from an outer periphery of the catalyst. 2. The dehydrogenation catalyst of claim 1 , wherein the predetermined thickness is realized by a rapid heat-treatment process and a rapid drying process of the single complex using an organic acid and an inorganic acid. 3. The dehydrogenation catalyst of claim 1 , wherein the catalyst is obtained using a process further including a calcination step and a reduction step, and the reduction step is realized by a high-temperature rapid reduction process. 4. The dehydrogenation catalyst of claim 1 , wherein the predetermined thickness is 300 to 500 μm thick from the outer periphery of the catalyst. 5. The dehydrogenation catalyst of claim 2 , wherein the inorganic acid is a hydrochloric acid, a nitric acid, or a sulfuric acid. 6. The dehydrogenation catalyst of claim 2 , wherein the organic acid further includes one among a formic acid, an acetic acid, a glycolic acid, a glyoxylic acid, an oxalic acid, a propionic acid, and a butyric acid, or a mixture including two thereof. 7. The dehydrogenation catalyst of claim 1 , wherein the auxiliary metal is selected from the group consisting of tin, germanium, gallium, and manganese. 8. The dehydrogenation catalyst of claim 1 , wherein the alkali metal is selected from the group consisting of potassium, sodium, and lithium. 9. The dehydrogenation catalyst of claim 1 , wherein the carrier is selected from the group consisting of alumina, silica, zeolite, and a composite component thereof.
