Title:
TRANSITION-METAL-BASED DEHYDROGENATION CATALYST FOR LOW-CARBON ALKANE, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/008171
Kind Code:
A1
Abstract:
Disclosed in the present invention are a transition-metal-based dehydrogenation catalyst for a low-carbon alkane, and a preparation method therefor and the use thereof, which belong to the technical field of petrochemical engineering. The catalyst uses at least one of the transition metal elements of V, Co, Ni, Zn and Fe as an active center and at least one of the non-metal elements of N, P and B as an auxiliary agent, and is prepared by impregnating a carrier in a solution containing a transition metal element and an auxiliary agent and then roasting same at 300-900ºC for 1-4 hours. The catalyst has the characteristics of a high conversion rate of low-carbon alkanes, a high selectivity of the product low-carbon olefin, a high sintering resistance, a good stability, etc.; moreover, the catalyst also overcomes the problems of existing dehydrogenation catalysts being unfriendly to the environment and being high in terms of price.
