Catalyst system for light hydrocarbon aromatization and carbon dioxide hydrogenation
A recently granted patent (Publication Number: US12005430B2) discloses a catalyst system designed for light hydrocarbon arylation or carbon dioxide conversion activities. The catalyst system comprises a porous material layer containing an active metal component and a molecular sieve layer. The active metal component, selected from a group including Zn, Pt, Ni, Co, and others, migrates into the molecular sieve layer during the conversion process, enhancing catalytic activity. The weight ratio between the porous material layer and the molecular sieve layer, as well as the active metal component to the porous material, are specified in the claims.
Furthermore, the patent details the preparation method of the porous material layer, which involves impregnating the material with a precursor of the active metal component and calcining it in an oxygen-containing atmosphere. The porous material is primarily a metal oxide like alumina or silicon oxide. The molecular sieve layer, crucial for capturing the active metal component during the conversion process, is a zeolitic molecular sieve with a microporous structure. The patent also covers methods for light hydrocarbon aromatization and carbon monoxide production using the catalyst system, highlighting its potential applications in enhancing catalytic activity and lifespan during heterogeneous catalysis processes through in-situ metal migration methods.
