Welcome to inquire! Contact: Feng Zhongying. Coking benzene hydrogenation as a trend industry has developed rapidly in recent years, has now reached a considerable scale. In terms of quality coking benzene hydrogenation not only fully meet the technical requirements of petroleum benzene, can achieve an effective separation of toluene, xylene and other chemicals, and the price also has a strong competitive advantage. Currently sold benzene to crude benzene hydrogenation as raw material production costs low coking benzene about 1600 yuan / t or benzene manufacturers representing petroleum benzene, the highest difference of 3 500 yuan / t, high profits to promote the coking benzene hydrogenation process Benzene is the basis for the rapid development of organic raw material, widely used in synthetic rubber, plastics, fibers, detergents, dyes, pharmaceuticals, pesticides and explosives production of benzene, also used as a solvent in the oil refining industry as to increase gasoline octane The admixture. Benzene is mainly taken from our aromatics extraction system. Before 1965, all the resources of benzene from coking industry byproduct, in 1965 began production of petroleum benzene. 70 years later, along with the production of large-scale petrochemical, oil and fiber devices, has gradually increased the proportion of petroleum benzene
