    摘要: A method for preparing p-xylene is provided. Raw materials containing methanol, naphtha and CO2 are introduced into a reactor filled with a catalyst for a reaction to produce p-xylene. By adding the methanol, the product distribution is adjusted, and the selectivity of p-xylene is obviously improved. In addition, components containing benzene and toluene in aromatic hydrocarbon products are returned to a reaction system and co-fed with the raw materials for a reaction to produce p-xylene, so that cyclic utilization of the raw materials is achieved, and the method has extremely high economic benefits. The method has a simple process and high feasibility, can greatly improve the selectivity and yield of p-xylene, has an important application value, and provides a new way for large-scale utilization of CO2.
