PRODUCTION OF PETROLEUM PLASTICIZER FOR AUTOMOBILE TIRES AND GEAR OIL FROM CATALYTIC CRACKING GAS OIL

Abstract

Catalytic gas oil has been investigated as a raw material for producing an environmentally friendly petroleum plasticizer of the base of gear oil. An oil plasticizer for automobile tires and an oil base for gear oil were obtained by cleaning gas oil by catalytic cracking, a multifunctional catalyst complex (MСC) from polycyclic aromatic hydrocarbons and organosulfur compounds. From raffinate after purification of catalytic gas oil, an environmentally friendly petroleum plasticizer for modern automobile tires was obtained. An oil base for a gear oil with high tribological characteristics was obtained from the oil fraction 390–440 °C with a high sulfur content obtained during the regeneration of spent MСС with a mixed solvent, after oxidation with hydrogen peroxide in the presence of rapeseed oil. Tests of the physico-chemical properties of the petroleum plasticizer were carried out according to GOST 1138, and tribological characteristics of the oil base and gear oil were tested according to GOST 9490.
