Title:
PROCESS FOR OBTAINING DISTILLATION OILS
Document Type and Number:
WIPO Patent Application WO/1995/005436
Kind Code:
A1
Abstract:
Distillation oils are obtained by treating oil fractions obtained from crude petroleum with selective solvents to obtain a refined product. That refined product is divided into two portions. The main portion undergoes hydrodeparaffination in the presence of a catalyst at a temperature of 280 to 370 �C and a pressure of 3 to 5 MPa, the raw material being fed in at a volume rate of 0.5 to 2.0/hr. A quantity (0.1 to 15 wt %) of the original refined product which has not undergone deparaffination is added to the deparaffined product thereby obtained.
