文摘

The structural-group composition and properties of the base oil samples obtained by solvent extraction technology and with the use of hydrofinishing of the solvent refined product have been studied. Sample 1 has been obtained via solvent refining and subsequent dewaxing, and samples 2 and 3 have been obtained according to a scheme comprising solvent refining and raffinate hydrofinishing over a NiMoW/ZnO-Al₂O₃ catalyst followed by dewaxing. The hydrotreating of the raffinate in the presence of the modified NiMoW/ZnO-Al₂O₃ catalyst can be conducted under mild conditions at 5.0 MPa.
