METHOD OF PREPARING INSULATING OIL COMPONENT Russian patent published in 1995 - IPC

Abstract RU 2047648 C1

FIELD: petroleum chemistry. SUBSTANCE: fraction of catalytic cracking product 200-360 C is subjected for hydrotreatment, deparaffination and additional hydrotreatment. Hydrotreatment and additional hydrotreatment were carried out preliminary in the presence of catalyst containing, cobalt or nickel oxide 0.5-5.0; molybdenum oxide 2-15, and aluminium oxide the rest. Catalyst of deparaffination has the following composition, molybdenum oxide 6-15; boron oxide 2-15; aluminium oxide 10-40, and high-silicon zeolite the rest. Process is carried out at 300-380 C, under pressure 3.5-6.5 MPa. EFFECT: improved method of oil component preparing. 3 cl
