Problems solved by technology

There are studies on the application of isoparaffin solvent oil with low impurity content in the field of metal stamping, but ExxonMobil’s Isopar series and Japan’s Idemitsu’s IP series are the main ones. The processes of these two companies use mixed C4 as raw material to oligomerize and add The fractions cut by hydrogen saturation have an isomer content greater than 98%. Due to the limitations of raw materials and processes in domestic production, there is still a large gap in the purity and performance of the isoparaffin solvent oil used and the international high-end solvent oil.

Embodiment 1

[0035] The raw material used is: Fischer-Tropsch crude liquid wax of Fischer-Tropsch synthesis process. After the raw material pretreatment unit, lightness removal, weight removal, and fractional distillation are carried out to obtain light white oil and industrial white oil.

[0036] The material after removing light and heavy components is used as molecular sieve feed. The molecular sieve feed is mainly C10-C16 normal paraffins and C10-C16 isoparaffins, and the mass ratio of the two is 0.8:1. Using the molecular sieve adsorption dewaxing process, the simulated moving bed process is adopted in the fixed bed equipped with solid adsorbent, and the selective adsorption and desorption are continuously carried out under the conditions of isothermal, isobaric and liquid phase, and normal alkanes and non-normal alkanes are separated. Paraffins are separated.

[0037] The adsorption separation part is mainly composed of an adsorption chamber equipped with 5A molecular sieve, a rota...

Embodiment 2

[0040] The raw materials used are: the mass ratio of Fischer-Tropsch crude liquid wax and naphtha in the Fischer-Tropsch synthesis process is 80:20. After the raw material pretreatment unit, lightness removal, weight removal, and fractional distillation are carried out to obtain light white oil and industrial white oil.

[0041] The material after removing light and heavy components is used as molecular sieve feed. The molecular sieve feed is mainly C10-C16 normal paraffins and C10-C16 isoparaffins, and the mass ratio of the two is 0.9:1.

[0042] All the other operating processes are the same as in Example 1.

[0043] In terms of parts by mass, the output of IP80 is 6.3 parts per 100 raw materials.

Embodiment 3

[0045] The raw materials used are: the mass ratio of Fischer-Tropsch crude liquid wax and naphtha in the Fischer-Tropsch synthesis process is 90:10. After the raw material pretreatment unit, lightness removal, weight removal, and fractional distillation are carried out to obtain light white oil and industrial white oil.

[0046] The material after removing light and heavy components is used as molecular sieve feed. The molecular sieve feed is mainly C10-C16 normal paraffins and C10-C16 isoparaffins, and the mass ratio of the two is 1:1.

[0047] All the other operating processes are the same as in Example 1.

[0048] In terms of parts by mass, the output of IP80 is 6.5 parts per 100 raw materials.

Abstract

The invention relates to an iso-paraffin solvent oil produced by taking Fischer-Tropsch crude liquid wax or Fischer-Tropsch crude liquid wax and naphtha as raw materials by adopting a Fischer-Tropschsynthesis process. The carbon chain length of alkanes in the product is concentrated between C12-C14, the distillation range is 210-245 DEG C, the iso-paraffin purity is high, impurities are few, cyclo-paraffin is not contained, the aromatic hydrocarbon content is smaller than 50 ppm, the flash point is larger than 80 DEG C, no pungent smell exists, and the solvent oil is convenient to store and transport, safe, green and environmentally friendly. The solvent oil is especially suitable for being used as a high-performance insecticide solvent or metal stamping oil.

Description

technical field [0001] The present invention relates to a kind of isoparaffin solvent oil and its application, specifically a kind of isoparaffin solvent produced by adopting Fischer-Tropsch crude liquid wax or Fischer-Tropsch crude liquid wax and naphtha as raw materials of Fischer-Tropsch synthesis process Oil and its application as a pesticide solvent or metal stamping oil. Background technique [0002] The development of isoparaffin solvent oil is very rapid, its product variety is increasing continuously, and its application field is expanding continuously. Because low-grade solvent oil contains more impurities such as sulfur, nitrogen, and aromatic hydrocarbons, it will produce pungent odors during use and cause harm to the human body. It has a low flash point and is flammable and explosive, especially in summer. The higher the temperature, the greater the risk of use. With the enhancement of social environmental protection and safety awareness, solvent oil varieties...
