Applications of Solid-State Nuclear Magnetic Resonance Spectroscopy in Methanol-to-Olefins Reaction

Chinese Journal of Magnetic Resonance, 2021
Methanol-to-olefins (MTO) is a prevalent industrial process for producing light olefins from the non-petroleum route. Molecular sieves are core catalysts for MTO owing to their unique pore structure and tunable acidity.

Insights into the size effect of ZnCr2O4 spinel oxide in composite catalysts for conversion of syngas to aromatics

Green Energy & Environment, 2023
Direct conversion of syngas to aromatics (STA) over oxide-zeolite composite catalysts is promising as an alternative method for aromatics production. However, the structural effect of the oxide component in composite catalysts is still ambiguous. Herein,

Crystal size sensitivity of HMOR zeolite in dimethyl ether carbonylation

Catalysis Communications, 2021
The effect of crystal size of HMOR from micro size to 50 nm, with the apparent similar acid site density, on catalytic performance for the dimethyl ether (DME) carbonylation was investigated. The crystal size of HMOR is sensitive to the deactivation rate
