Abstract
The present disclosure relates to the catalytic field, and discloses a catalyst system and a light hydrocarbon aromatization method, a carbon dioxide hydrogenation process and a method for enhancing the catalytic activity and/or lifetime of the catalyst during a heterogeneous catalysis process, the catalyst system comprising a porous material layer containing an active metal component and a molecular sieve layer. The catalyst system provided by the present disclosure exhibits desirable catalytic activity, stability, renewability and selectivity, thus has significant benefits.
