Title:

IRON-POTASSIUM-CERIUM-BASED COMPOSITE OXIDE CATALYST, AND PREPARATION AND APPLICATION THEREOF

Document Type and Number:

WIPO Patent Application WO/2022/078371

Kind Code:

A1

Abstract:

Disclosed are an iron-potassium-cerium-based composite oxide catalyst, and a preparation and application thereof; in addition to the metal elements Fe, K, and Ce, the catalyst also comprises a metal element M, the metal element M being selected from at least one of Group IIA metal elements, non-Cr Group VIB metal elements, and Group IVA metal elements, the total base amount of the catalyst being in the range of 0.32-0.46 mmol/g and the strong base amount being in the range of 0.061-0.082 mmol/g. When used for a dehydrogenation reaction of alkyl aromatic hydrocarbons, even at a lower dehydrogenation reaction temperature and an ultra-low water ratio, the catalyst has high selectivity, catalytic activity, and stability, and few by-products, having the features of low material consumption and low energy consumption.
