Description

technical field

[0001] The invention relates to a catalyst for directly synthesizing aromatic hydrocarbons from synthesis gas, a preparation method and application thereof, in particular to a catalyst, preparation method and application for synthesizing aromatic hydrocarbons from synthesis gas through methanol and dimethyl ether. Background technique

[0002] Benzene, toluene, and xylene (BTX for short) are important organic chemical raw materials, mainly used to produce chemical products such as chemical fibers, plastics, and rubber. In recent years, with the continuous expansion of polyester production worldwide, the demand for PTA (terephthalic acid) and PX (paraxylene) has increased rapidly. Aromatics resources mainly come from catalytic reforming oil, pyrolysis gasoline and coal tar. With the development of the oil refining industry, the proportion of aromatics using petroleum as raw material is gradually increasing, accounting for more than 98% abroad and more than 85...
