Embodiment 1
[0019] Embodiment 1, the preparation of environment-friendly rubber filler 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) Using the hydrotreated oil obtained above as a raw material, extract it 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; after the raffinate is removed from furfural, ...
