Abstract

The invention discloses a production method of high-boiling-point aromatic solvent oil. The production method comprises the following steps: performing catalytic hydrogenation lightweight process on C10 aromatic hydrocarbon as a raw material, and performing rectification separation to obtain fraction with the temperature of 150-180 DEG C or fraction with the temperature of 180-215 DEG C as the high-boiling-point aromatic solvent oil, wherein a hydrogenation catalyst adopts an amorphous silicon aluminum composite carrier, and active ingredient-loaded oxides are nickel oxide, molybdenum oxide, tungsten oxide and phosphorus oxide; the total weight of the active ingredient oxides is 20%-60% the weight of the silicon aluminum composite carrier; the weight ratio of nickel oxide to molybdenum oxide to tungsten oxide to phosphorus oxide is (10 to 30):(50 to 85):(3 to 20):(0.5 to 10). The production method is simple in process and convenient for continuous production of industrialized operation.

Description

technical field [0001] The invention relates to a production method of high-boiling aromatic oil, which belongs to the field of petrochemical industry. Background technique [0002] As one of the main petroleum products, solvent oil, together with gasoline, kerosene, diesel oil and lubricating oil, is called the five major categories of petroleum products in my country. Solvent oil is widely used in industries such as medicine, chemical industry, polymer materials, rubber and paint. At present, there are three sources of main raw materials for solvent oil production: straight run fraction of crude oil, catalytic reforming raffinate oil and condensate oil, which need to be refined to improve color, smell and stability. Divided according to the range of distillation range, the common ones are No. 6 solvent oil (distillation range 60-90°C), No. 90 solvent oil (distillation range 90-120°C), No. 150 solvent oil (distillation range 120-150°C), No. 200 solvent oil Solvent oil (d...
