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.

Catalyst system and light hydrocarbon aromatization method, carbon dioxide hydrogenation process and method for enhancing catalyst lifetime

A catalyst for converting hydrocarbon, a method of making the same, and a method of using the same are provided. Such a catalyst includes a zeotype microporous material, a binder material, and a metal phosphide, which can be in a range of from 0.01% to 10% by weight of a total weight of the catalyst. For example, such a catalyst can be used to convert light alkene or alkane into aromatic hydrocarbon such as benzene, toluene, xylenes, and a combination thereof. The alkene may be ethylene, propylene, butylene, or a combination thereof. The alkene may be supplied directly or from a stream converted from light alkane such as methane, ethane, propane, butane, or a combination thereof.

Catalyst for converting light olefin to aromatics, method of making and method of using the same

The present disclosure provides a modified catalyst, and preparation method and a method for producing aromatic hydrocarbons by aromatization of olefins using the modified catalyst. The modified catalyst comprises an acidic molecular sieve and an olefin aromatization active metal component, the total acid amount of the catalyst as measured by NH-TPD method is not higher than 0.35 mmol/g, and ratio of the strong acid to weak acid is within a range of 0.8-1.2.
