Embodiment 1

[0022] Embodiment 1, the preparation of environment-friendly rubber oil

[0023] (1) Using the third-line distillate oil produced by the industrial plant of Zhonghai Asphalt Co., Ltd. as raw material (see Table 1 for the properties of the raw material oil), the test was carried out in a solvent refining small test device (the total feed amount of raw material oil and solvent is 3kg / h, Random packing is placed in the tower, the number of theoretical plates is 3 theoretical plates), the solvent is furfural, the weight ratio of agent to oil is 3.5:1, the temperature at the top of the refining tower is 130°C, and the temperature at the bottom of the tower is 95°C; The bottom product is extract liquid, and after recovering the solvent, extract oil is obtained, and the extract oil is used as the raw material for hydroprocessing; the top product of the refining tower is refined liquid, and the refined oil is obtained after recovering the solvent, and the refined oil is used as naphthe...

Embodiment 2

[0026] Embodiment 2, the preparation of environment-friendly rubber oil

[0027] (1) The used raw material oil, solvent refining tower and refining solvent are the same as in Example 1; wherein, the weight ratio of agent to oil is 2.5:1, the temperature at the top of the refining tower is 105°C, and the temperature at the bottom of the tower is 80°C. The bottom product is extract liquid, and after recovering the solvent, extract oil is obtained, and the extract oil is used as the raw material for hydroprocessing; the top product of the refining tower is refined liquid, and the refined oil is obtained after recovering the solvent, and the refined oil is used as naphthenic base oil.

[0028] (2) The hydrotreating unit and hydrotreating catalyst used are the same as in Example 1; wherein, the hydrotreating reaction temperature is 365° C., the volume ratio of hydrogen to oil is 1000:1, and the volume space velocity is 0.3h -1 , the hydrogen partial pressure is 10.0MPa, the hydrotr...

Embodiment 3

[0030] Embodiment 3, the preparation of environment-friendly rubber oil

[0031](1) The fourth line distillate produced by the industrial plant of Zhonghai Asphalt Co., Ltd. is used as raw material (the properties of the raw material oil are shown in Table 1), the solvent refining tower is the same as that of Example 1, and the solvent refined with N-methylpyrrolidone ( Water content 2.0%, weight percent), agent oil weight ratio is 2.7: 1, refining tower tower top temperature is 110 ℃, tower bottom temperature is 80 ℃, refining tower tower bottom product is extract liquid, after reclaiming solvent, obtain extract oil, The extracted oil is used as the raw material for hydrotreating; the top product of the refining tower is a refined liquid, and the refined liquid is recovered from the solvent to obtain a refined oil, which is used as a naphthenic base oil.

[0032] (2) The obtained extracted oil was subjected to hydrotreating test in a hydrotreating pilot plant, the hydrotreati...

Abstract

The invention discloses environment-friendly rubber oil and a preparation method thereof. The preparation method comprises the following steps of: (1) placing naphthenic-base distillate oil in a solvent refining tower to carry out solvent refining to obtain refined liquid at the top of the solvent refining tower and extracted liquid at the bottom of the solvent refining tower, recovering the solvent from the refined liquid to obtain refined oil and receiving the solvent from the extracted liquid to obtain extracted oil; and (2) hydrogenating the extracted oil to obtain hydrogenated oil; and distilling the hydrogenated oil for removing light fraction to obtain the environment-friendly rubber oil. The preparation method has the following beneficial effects: after raw material oil is refined with the solvent, the refined oil has the characteristics of low aromatic hydrocarbon content, high saturated hydrocarbon content and light color and is a high-quality naphthenic-base basic oil with a wide application scope; in addition, the non-environment-friendly extracted oil with low additional value is further subjected to the hydrogenation treatment and then is converted to be the environment-friendly rubber oil with high additional value, thus the integral economic benefits of the naphthenic-base distillate oil are greatly improved.

Description

technical field [0001] The invention relates to an environment-friendly rubber oil and a preparation method thereof, belonging to the field of petrochemical industry. Background technique [0002] Oils used in rubber synthesis or rubber processing are collectively referred to as rubber oil. As an important additive, rubber oil is widely used in the rubber industry. After the rubber is filled with oil, the processability and use performance are improved, while the output of rubber is increased and the cost is reduced. As a big tire manufacturing country in China, tire oil has become the largest application field of rubber oil, and more than one-third of domestic tires are exported overseas. [0003] In recent years, the voice of environmental protection has become higher and higher, and the application of green environmental protection materials has attracted much attention. The harm of traditional high-aromatic rubber oil to human health and the pollution of the environmen...
