[0002] The benzene hydrogenation project includes production facilities and production auxiliary facilities, mainly: hydrogen production, hydrogenation, pre-distillation, extraction, oil depot, loading and unloading platform, etc., to produce high-purity benzene, nitration-grade toluene, xylene, non-aromatic hydrocarbons, solvent oil, etc. The crude benzene hydrogenation reaction generally uses a copper-zinc-aluminum catalyst, which has the advantages of high catalytic activity, good stability, and good thermal stability. In addition, precious metal catalysts such as platinum and palladium can also be used, but the cost is relatively high. The products generated by the reaction will contain impurities such as o- and p-dimethylbenzene and phenylmethylacetic acid on the benzene ring, which require post-treatment. Generally, solvent extraction, distillation and other methods are used for purification to meet the product purity requirements. The above is a relevant introduction to the crude benzene hydrogenation process. Through the selection of catalysts and the optimization of reaction conditions, In order to achieve high efficiency, high selectivity and high stability of crude benzene hydrogenation reaction, it should be emphasized that in practical applications, it is also necessary to adjust and optimize according to specific circumstances to achieve the best reaction effect. Benzene, toluene, xylene (BTX for short) are aromatic hydrocarbons and are important basic organic chemical raw materials. Downstream products derived from aromatic hydrocarbons are widely used in the manufacture of three major synthetic materials (synthetic plastics, synthetic fibers and synthetic rubber) and organic raw materials and various intermediates. Pure benzene is used in large quantities to produce fine chemical intermediates and organic raw materials. In addition to being used for disproportionation to produce benzene and xylene, toluene is mainly used in the production of toluene diisocyanate, organic raw materials and a small amount of intermediates. In addition, it is also used as a solvent in coatings, adhesives, inks and pesticides.
