Problems solved by technology

[0003] The traditional method of producing special solvent oil from kerosene fractions is acid-base clay refining method, but the product quality is not high, the yield is low, and a large amount of acid slag, alkali slag and waste water are produced in the production process, and the equipment is seriously corroded
The patent CN1157847A invented by Nanjing Xingda Petrochemical Technology Industry and Trade Co., Ltd. adopts the hydrogenation method for refining. The raw material oil and hydrogen react under the nickel catalyst. The method conditions are mild, the liquid yield is high, and the produced oil is non-toxic and harmless, and there is no three wastes and other environmental protection issues, the disadvantage is that the process cannot guarantee that the product has no odor
Patent CN1258720A hydrotreats the liquid wax obtained by dewaxing kerosene fractions through molecular sieves. The product is non-toxic, harmless and tasteless, and the aromatic content is less than 0.1%. range is too narrow

Embodiment 1

[0015] 34g of industrial hydrated titanium oxide, 120g of SB aluminum hydroxide powder, after mixing evenly, add 8g of kale powder, 24g of polyethylene glycol, 5g of citric acid, 30ml of 65% nitric acid and appropriate amount of deionized water, knead and extrude to Φ1.6mm The strips were dried at 110°C for 4 hours, and then calcined at 550°C for 4 hours to make a carrier.

[0016] Add ammonium metatungstate and nickel nitrate into deionized water, and the solution composition is 80g ammonium metatungstate / 100ml, nickel nitrate 12g / 100ml. Immerse 100g of carrier in 200ml of the above solution, soak at 40°C for 2h, filter, dry at 110°C for 4h, and then calcinate at 500°C for 4h to prepare Catalyst A. The properties of Catalyst A are shown in Table 1.

Embodiment 2

[0018] 34g of industrial hydrated titanium oxide and 120g of SB aluminum hydroxide powder were prepared as the carrier according to the method in Example 1. Ammonium metatungstate, ammonium molybdate, and nickel nitrate were added to deionized water, and the solution consisted of ammonium metatungstate 90g / 100ml, ammonium molybdate 25g / 100ml, and nickel nitrate 22g / 100ml. 100 g of support was subjected to saturated spray impregnation. Stand at room temperature for 10 hours, dry at 110°C for 4 hours, and then calcinate at 500°C for 4 hours to prepare catalyst B. The properties of Catalyst B are listed in Table 1.

Embodiment 3

[0020] Using straight-run kerosene I as the raw material, the process conditions of the above-mentioned catalyst A were investigated in a 100ml medium-sized fixed-bed hydrogenation unit. Firstly, the catalyst is presulfided with sulfide-containing kerosene to convert the active metal on the catalyst from an oxidized state to a sulfided state. After being stable for a period of time, the activity investigation test was started. The properties of straight-run kerosene I are shown in Table 2.

[0021] Adopt the straight-run kerosene I shown in table 2, under the effect of the catalyst A shown in table 3 and the hydrorefining process condition shown in table 3, straight-run kerosene I is carried out hydrotreating, the character of gained product is as shown in the table 3.

[0022] It can be seen from Table 3 that using catalyst A, high-quality kerosene-type special solvent oil can be produced through hydrofining. The product is water-white in color, non-toxic, harmless and tast...

Abstract

The present invention discloses a production method of kerosene solvent naphtha and its catalyst for said method. In said method the raw material oil is straight-run kerosene or hydrocracked kerosenefraction with 130-300 deg.c, and a hydrogenation method is adopted to produce high-quality kerosene solvent naphtha. Said used hydrogenation catalyst is W-Ni-TiO2-Al2O3 or W-Mo-Ni/TiO2-Al2O3, and thehydrogen fractional pressure required for hydrogenation is 6.0-15.0 MPa, reaction temp. is 220-360 deg.C, and the volume space velocity is 0.3-2.0 h(-1), and the hydrogen-oil volume ratio is 300-800.The product produced by using said invented mether is white in colour, and is non-toxic, harmless and smelless, its sulful and nitrogen contents are less than 1 microgram/g, and its arene content is less than 200 microgram/g.

Description

technical field [0001] The invention relates to a production method of solvent oil, in particular to a production method of kerosene fraction hydrogenation to produce solvent oil and a catalyst used in the method. Background technique [0002] Refined kerosene products are extremely versatile. It is mainly used as high-quality aerosol solvent and base oil for metal rolling oil such as aluminum foil, and can also be used in fine chemical fields such as high-quality electronic cleaning oil, industrial white oil and edible oil processing, food packaging, cosmetic blending, and spice extraction. In addition, kerosene should be added in the production process of low-temperature lubricants, ink solvents, non-aqueous electroplating solvents, textile printing and dyeing auxiliaries, glazing agents, industrial cleaning agents, and daily cleaning agents such as shampoo, hair cream, and cosmetics. type solvent oil. According to market demand, refined kerosene can be obtained after re...
