Description

technical field

[0001] The invention relates to a method for saturated hydrogenation of petroleum hydrocarbon cracking C9 fractions, the method is suitable for hydrogenating unsaturated hydrocarbon raw materials into corresponding saturated hydrocarbons, especially suitable for cracking alkynes in petroleum hydrocarbon cracking C9 fractions , Diolefins, and monoolefins are hydrogenated to the corresponding alkanes. Background technique

[0002] C 9 Distillate, which is extracted and separated from C 5 Fraction, C 6 ~C 8 The remaining fraction after the fractionation accounts for about 10% to 15% of the total ethylene production. cleavage C 9 It is a good raw material for producing aromatic solvent oil. But in cracking C 9 It contains a large amount of olefins and a certain amount of impurities such as sulfur and nitrogen, and has a strong odor and poor stability. At present, most ethylene production plants are directly used or sold as low-grade fuels, and the utilizat...
