| petroleum chemicals | naphtha is mainly used as raw material for cracking, catalytic reforming and ammonia production, as well as as chemical raw material and general solvent. naphtha, also known as "petroleum English", "crude gasoline" and "straight-run gasoline", is a light petroleum product. The word is derived from Persian and refers to volatile petroleum products, generally referring to the fraction of 30~220 ℃. Naphtha in a narrow sense, also known as light naphtha, refers to the straight-run gasoline fraction from the initial distillation point to 130°C. Since the 2060s, with the development of the petrochemical industry, naphtha has become an important raw material for the cracking of tube furnaces to produce ethylene, propylene, benzene, toluene and xylene. As a raw material for cracking, the content of alkanes and naphthas in the composition is required to be not less than 70% (volume). When heavy naphtha is used as a raw material for catalytic reforming, when it is used to produce high-octane gasoline components, the feed is a wide fraction with a boiling point range of 80~180 ℃; when it is used to produce aromatics, the feed is a narrow fraction with a boiling point range of 60~165 ℃. the technology of using naphtha as cracking raw material is very mature, but the source of naphtha is limited because the yield of naphtha generally does not exceed the 10% of crude oil. naphtha can also be used as tractor fuel, reforming and petrochemical raw materials, as well as paint, rubber and other solvents. |
| the cracking raw material of the refinery | naphtha is also called straight run gasoline, the fraction at the initial distillation point ~ 200 ℃ is called full naphtha, and the fraction at the initial distillation point ~ 130 ℃ is called light naphtha. According to the processing depth, it is divided into straight-run naphtha and secondary processing naphtha. Straight-run naphtha is a fraction fractionated by regular pressure distillation of crude oil; secondary processing naphtha refers to naphtha obtained by secondary processing such as coking unit and hydrocracking unit in refinery. due to different crude oil producing areas and different crude oil properties, the yield of straight-run naphtha varies greatly. the low yield is only 2% ~ 3% of crude oil, and the high yield can reach 30% ~ 40%. China's crude oil is generally heavy, and the yield of naphtha is only 5% ~ 15%%. since the reformer needs fractions above 60 ℃, before reforming naphtha, the fractions before 60 ℃ need to be pulled out. it is usually said that the fractions from the initial distillation point to 60 ℃ of this part are pulled out as head oil. The head oil is mainly C3 ~ C6 hydrocarbons, which belongs to the category of naphtha and is a good raw material for cracking. |
| solvent naphtha | solvent naphtha is colorless or light yellow liquid. Coked aromatic hydrocarbon mixtures obtained from the fractionation of coal coke light oil. The boiling range is 120~200 ℃, which is mainly composed of toluene, xylene isomer, ethylbenzene, cumene, etc. The relative density is (20 ℃/ 4 ℃) 0.85~0.95, the flash point is 35~38 ℃, and the chemical properties are similar to toluene and xylene. It can be miscible with ethanol/acetone, etc., can dissolve glycerol rosin ester, asphalt, etc., and is mainly used as a solvent for coal tar pitch and petroleum pitch. Adding aliphatic hydrocarbon solvent to naphtha can improve its solubility. Among them, high boiling point fractions can also be used as diluents for synthetic resins and cellulose esters. |
