Embodiment 1
[0019] Embodiment 1, the preparation of environment-friendly rubber oil
[0020] The preparation process is as figure 1 The flowchart shown.
[0021] (1) Using Zhonghai SZ36-1 minus three-line distillate oil (Zhonghai Asphalt Co., Ltd., product name is SZ3#, see: http: / / www.zhonghaibitumen.com) as raw material, and carry out hydrogenation through a low-pressure hydrotreating unit treatment to obtain hydrotreated oil; the hydrogenation conditions are: hydrogen partial pressure 6.4Mpa, reaction temperature 280°C, volume space velocity 2.0h -1 , the ratio of hydrogen to oil is 600:1, and the hydrotreating catalyst is RL-1 lubricating oil hydrotreating catalyst (Sinopec Changling Refining and Chemical Co., Ltd.);
[0022] (2) Use the obtained hydrotreated oil as raw material, extract with furfural in the extraction tower, obtain raffinate at the top of the tower, and obtain extract at the bottom of the tower; after the raffinate is removed from furfural, it is a primary refined ...
Embodiment 2
[0025] Embodiment 2, the preparation of environment-friendly rubber oil
[0026] The preparation process is as figure 1 The flowchart shown.
[0027] (1) Using Zhonghai SZ36-1 minus three-line distillate oil (Zhonghai Asphalt Co., Ltd., product name is SZ3#, see: http: / / www.zhonghaibitumen.com) as raw material, and carry out hydrogenation through a low-pressure hydrotreating unit treatment to obtain hydrotreated oil; the hydrogenation conditions are: hydrogen partial pressure 3.2Mpa, reaction temperature 310°C, volume space velocity 1.5h -1 , the ratio of hydrogen to oil is 400:1, and the hydrotreating catalyst is RL-1 lubricating oil hydrotreating catalyst (Sinopec Changling Refining and Chemical Co., Ltd.);
[0028] (2) Using the hydrotreated oil obtained above as a raw material, extract with furfural in the extraction tower, obtain a raffinate at the top of the tower, and obtain an extract at the bottom of the tower; the raffinate is a primary refined oil after removing f...
Embodiment 3
[0031] Embodiment 3, the preparation of environment-friendly rubber oil
[0032] The preparation process is as figure 1 The flowchart shown.
[0033] (1) Using Zhonghai SZ36-1 minus three-line distillate oil (Zhonghai Asphalt Co., Ltd., product name is SZ3#, see: http: / / www.zhonghaibitumen.com) as raw material, and carry out hydrogenation through a low-pressure hydrotreating unit treatment to obtain hydrotreated oil; the hydrogenation conditions are: hydrogen partial pressure 3.2Mpa, reaction temperature 330°C, volume space velocity 0.8h -1 , the ratio of hydrogen to oil is 200:1, and the hydrotreating catalyst is RL-1 lubricating oil hydrotreating catalyst (Sinopec Changling Refining and Chemical Co., Ltd.);
[0034](2) Using hydrotreated oil as raw material, carry out extraction in the extraction tower, the raffinate is obtained at the top of the tower, and the extract is obtained at the bottom of the tower; after the raffinate is removed from furfural, it is a primary ref...
