9 Claims

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.
