摘要：

Para-xylene is an important aromatic material in petrochemical industry. In recent decades, China’s demand for para-xylene has been growing. In order to ensure the healthy and steady development of para-xylene industry in China, it is urgent to develop a more low-cost and efficient para-xylene production process. Shape-selective alkylation of toluene with methanol to para-xylene is one of the most promising and competitive new technologies for para-xylene production. However, how to improve the stability of the catalysts while maintaining their high selectivity is still challenging. The formation of low-carbon olefins is one of the main reasons for the deactivation of the catalysts. Based on the discussion of the catalytic reaction mechanisms and research progress of the catalyst, we believe that the exploitation of highly selective and stable catalysts can be driven from three directions: synthesis of molecular sieve parent of shape-selective effect and excellent diffusion property, coordinated regulation of the pore structure and acid properties of molecular sieves, and inhibition of the formation of low-carbon olefins. © 2022 Chemical Industry Press.
