Title:

MODIFIED ZINC ALUMINATE CARRIER, LOW-CARBON ALKANE DEHYDROGENATION CATALYST, PREPARATION METHOD FOR LOW-CARBON ALKANE DEHYDROGENATION CATALYST, AND USE OF LOW-CARBON ALKANE DEHYDROGENATION CATALYST

Document Type and Number:

WIPO Patent Application WO/2024/008164

Kind Code:

A1

Abstract:

The present invention relates to the technical field of petrochemical industry. Disclosed are a modified zinc aluminate carrier, a low-carbon alkane dehydrogenation catalyst, a preparation method for the low-carbon alkane dehydrogenation catalyst, and a use of the low-carbon alkane dehydrogenation catalyst. The chemical composition of the modified zinc aluminate carrier has a general formula of ZnxMyAl2O4; M is selected from one or more of alkali metal elements and alkaline earth metal elements; and the modified zinc aluminate carrier has a porous structure. In the catalyst provided by the present application, at least one of noble metals, i.e., Pt, Pd, Ru, and Rh is used as an active component, at least one of transition metals, i.e., Ga, V, In, Sn, Mn, Ce, Fe, and Ni is used as an additive, and the modified zinc aluminate carrier is used as a carrier. The catalyst prepared by the modified zinc aluminate carrier has the characteristics of high propane conversion rate, high product propylene selectivity, strong sintering resistance, good stability and the like.
