Abstract
The invention discloses a catalyst for preparing styrene through ethylbenzene dehydrogenation as well as a preparation method and application of the catalyst. The catalyst comprises Fe, K, Ce, Mo, alkaline earth metal, carbon and at least one of Cl element and Br element. When the catalyst is used in ethylbenzene dehydrogenation reaction, high conversion rate of ethylbenzene can be maintained, and selectivity of styrene can be remarkably improved.
