Abstract

Petroleum oils are obtained by vacuum distillation of fuel oil and subsequent purification, with solvents, of the fraction which boils off at above 490 °C to obtain a refined residue. The said refined residue is divided into two portions preferably in a weight ratio of 30:70 to 70:30 as appropriate. The first portion undergoes deparaffination with selective solvents to produce a component consisting of residual deparaffined oil and petrolatum. The petrolatum obtained is mixed with the second portion of the refined residue and subjected to catalytic hydrodeparaffination, the hydrodeparaffined product thus obtained being subsequently fractionated. The residual oil fraction obtained is mixed with the residual deparaffined oil component.

Description

SP0S0B RULES ΚΕΦΤЯΗЫΧ ΜΑСΕЛ ьLevel of technology

The inventive invention is not available for processing, and the name is given to the process for the production of non-distilled 5 oils.

Essential oils that are produced and processed are one of the most non-existent products. The SENDED DISCUSSIONS received by the vacuum of non-ferrous oil are subject to various types of calculations for removal from them of large amounts of waste and property losses: The main characteristics of the oils used are viscosity, its change with temperature, its stability and oxidation are high, and the temperature is high. 15 This invention solves the problem of producing residual oily oils with a high yield.

The processed de-parine separates from the deasbalted portion and the enriched depleted residues. The end of the dispensing of the oil is δЗ, 5-65, δ (see Зрс-πпэпцп заявпїуюп заявп заявп заявп 02п 02п 02 application 0216448, ι \ 4ПΚ С 10 α 67/04, 1987). 25 Application No. 027Ι26δ, Ж. From 10 & 67/04, 1988, two methods for the production of un-ethene oils were described. It aids in the state of mild disease and uncontrolled frustrated products with high-quality oil in- volves. The last has been encouraged by the catalytic 30th hydrodepository for the benefit of the catalyser, and the good: good LYΧΟD of crude oils makes 65,4-78,2 ^.

This method is relatively simple and does not prevent the production of oils with a sufficiently high yield.
