Abstract
An ethylbenzene dehydrogenation catalyst, a preparation method therefor, and the use thereof are provided. The catalyst includes Fe2O3, K2O, CeO2, MoO3 and CaO. The exposed crystal face area of CeO2 (100) accounts for 60% or more of the total exposed crystal face area of CeO2. The catalyst is used in a reaction for preparing styrene by means of dehydrogenating ethylbenzene at a low water ratio, and has high activity and stability.
Claims20
