LUBRICANT BASE OIL

A method for producing a hydrocarbon-based lubricating base oil comprising: a step of hydrocracking/hydroisomerization of a feed stock oil containing normal paraffins, so that a urea adduct value of an obtained treated product is not greater than 4 % by mass, a viscosity index is 100 or higher, an a...

Beschreibung
Zusammenfassung:	A method for producing a hydrocarbon-based lubricating base oil comprising: a step of hydrocracking/hydroisomerization of a feed stock oil containing normal paraffins, so that a urea adduct value of an obtained treated product is not greater than 4 % by mass, a viscosity index is 100 or higher, an average of carbon atoms number is 23-31 as determined by gas chromatography distillation, a value obtained by dividing an integral value of a peak in 30 ppm by an integral value of total peaks in the range from 0 ppm to 50 ppm for the 13 C-NMR spectrum is 0.1-0.2, and a product of a value obtained by dividing an integral value of peaks attributed to tertiary carbon atoms by an integral value of total peaks in the range of from 0 ppm to 50 ppm for the 13 C-NMR spectrum, and the average of carbon atoms number, is 1.8-2.5.
