PROCESS OIL, PROCESS FOR PRODUCTION OF DEASPHALTED OIL, PROCESS FOR PRODUCTION OF EXTRACT, AND PROCESS FOR PRODUCTION OF PROCESS OIL
Document Type and Number:
WIPO Patent Application WO/2006/129616
Kind Code:
A1
Abstract:
Disclosed are: a process oil produced by using a deasphalted oil which is produced by deasphalting a vacuum residual oil from crude oil as a starting material, the process oil having the following properties (a) to (f) and; a process for producing the process oil: (a) polycyclic aromatic hydrocarbon (PCA) content: less than 3% by mass; (b) viscosity (at 100&ring C): 40 to 70 mm2/s; (c) aniline point: 85 to 100&ring C; (d) flash point: 250&ring C or higher; (e) aromatic hydrocarbon content: 40 to 55% by mass; and (f) polar substance content: 10 to 15% by mass. Also disclosed are: a process oil produced by mixing an extract which is produced by deasphalting a vacuum residual oil from crude oil and then extracting the resultant product with a solvent with a lubricating base oil which has a polycyclic aromatic hydrocarbon (PCA) content of less than 3% by mass, the process oil having the following properties (a) and (i) to (n) and; a process for producing the process oil: (a) polycyclic aromatic hydrocarbon (PCA) content: less than 3% by mass; (i) viscosity (at 100&ring C): 30 to 80 mm2/s; (j) aniline point: 90&ring C or lower; (k) flash point: 240&ring C or higher; (l) benzo(a)pyrene content: 1 ppm by mass or less; (m) content of specific aromatic hydrocarbons: 10 ppm by mass or less; and (n) polar substance content: 10 to 30% by mass.
