Vacuum distillate hydrocracking used in lubricant oils manufacture

This paper presents the results of the experimental hydrocracking determina tions, done upon a paraffinous, sulphurous distillate, under various temper ature, pressure and volume rare conditions, on Ni-Mo-catalyst. The hydrocra ked oil yields and some characteristics, such as viscosity, viscosity index etc., are correlated with the hydrocracking process working parameters val ues.
