Advances in the catalysis of methanol to aromatics reaction

In this paper,recent advances in the catalysis of methanol-to-aromatic (MTA) reaction have been reviewed. Effects of catalyst preparation and reaction conditions on the MTA performance were focused. From the point of catalyst preparation,modification with different metals,different metal modification methods,addition of catalytic promoters and improvement of diffusion properties on the activity and selectivity of MTA reaction were discussed. Besides,co-feeding other reactant with methanol as a modification of reaction condition also helped to understand the reaction mechanism and influenced the reaction results. It is important and interesting to combine various modifications without losing their advantages in contributing to the MTA catalytic performance.
