Problems solved by technology

[0008] 1. A set of oil hydrogenation device can only be suitable for one type of oil hydrogenation reaction, and the product structure is single
[0009] 2. In order to ensure that the vulcanized catalyst does not lose S and deactivate, the vulcanized catalyst is only suitable for processing high-sulfur oil products, and cannot process low-sulfur or sulfur-free oil products
[0011] 3. The current organic heat carrier processing technology is a sulfur-free catalyst, and the subsequent process has no desulfurization process, so it is difficult to remove trace inorganic sulfur in oil products
[0012] 4. Using white clay to refine and decolorize, the process is complicated and solid waste is generated

Abstract

The invention discloses a high-sulfur light distillate and organic heat-carrier raw oil mixing process and belongs to the technical field of oil hydrogenation. The process is characterized by proportionally mixing high-sulfur light distillate and organic heat-carrier raw oil to produce lubricant base oil and light white oil; hydrogenation conditions for a first reactor and a second reactor: hydrogen partial pressure ranges from 15 MPa to 17.2 MPa, content of H2S of recycle gas ranges from 100 ppm to 500 ppm, airspeed ranges from 0.78 h<-1> to 0.83h<-1>, volume ratio of hydrogen to oil ranges from 500 to 600, and reaction temperature ranges from 300 / 280 DEG C to 306 / 285 DEG C; products of hydrogenation reaction are separated to obtain the lubricant base oil and the light white oil. According to the technology, different raw oil such as the high-sulfur light distillate and the organic heat-carrier are mixed proportionally, and then are used for producing two different products, namely the lubricant base oil and the light white oil, through the same device and the same catalyst.

Description

technical field [0001] The invention discloses a mixed processing technology of high-sulfur light distillate oil and organic heat carrier raw material oil, which belongs to the technical field of hydrogenation of oil products. Background technique [0002] The oil hydrogenation process refers to the process of reacting the raw oil and hydrogen through the catalysis of the catalyst at a certain temperature and hydrogen pressure to improve the quality of the oil or obtain the target product. In the oil hydrogenation process, different catalysts are selected for hydrogenation reaction according to different raw material properties, and different target products are obtained.
