Naphtha can separate a variety of organic raw materials, such as gasoline, benzene, kerosene, asphalt, etc. Naphtha is an important raw material for the production of ethylene and propylene through the cracking of tube furnaces and the production of benzene, toluene and xylene through catalytic reforming. As a cracking raw material, the content of alkanes and naphthenes in the naphtha composition is required to be no less than 70% (volume). When used as a catalytic reforming raw material for the production of high-octane gasoline components, the feed is a wide fraction with a boiling point range of 80-180℃. When used for the production of aromatics, the feed is a narrow fraction with a boiling point range of 60-165. ℃. Actual relevance: As the market price of naphtha is much lower than unleaded gasoline for vehicles (the price difference is 600-1200 yuan per ton), the use of naphtha and petrochemical additives to blend unleaded gasoline for vehicles has become a private petrochemical enterprise to increase the profit of refined oil Important way. my country's crude oil is relatively heavy, and the supply of naphtha is very tight. Ethylene plants, reformers, and naphtha hydrogen production plants compete for raw materials.
