The medium-base crude oil is used as raw material to develop solvent-refined medium-pressure hydrotreating technology, and domestic crude oil or hydrocracking tail oil of Middle East crude oil is used as raw material to develop hydrogen dehydration and isomerization technology, using paraffin-based crude oil as raw material. , Develop high-pressure hydrotreating-refining-hydrogenation-refining process technology, submit complete sets of technologies for base oil production that meet the high-diameter index; use soft wax and other heavy wax pastes as raw materials to develop ultra-high quality index The complete set of technologies for base oil production; the use of high-knockout index base oils to develop high-quality SH gasoline engine oils and biodegradable hydraulic oils, biodegradable hydraulic greases and other specialty lubricants.
China has reached the world level in the production technology of high-grade lubricant base oils and some ancillary products, forming a relatively complete high-grade lubricant production technology. In terms of lubricant base oil technology, there are both lower investment, lubricating oil medium-pressure hydrogenation technology combined with the features of refinery existing devices, and high-pressure hydrogen-based hydrogen hydrogenation production technology, which is currently the most cutting-edge Lubricating oil isomerization dewaxing technology; in terms of lubricating oil products, it covers high-grade internal combustion engine oil and its supporting additive products and environmentally friendly green lubricant grease products.
