METHOD FOR ADSORPTION REFINING OF OIL STOCK TO PRODUCE CAPACITOR OIL Russian patent published in 2015 - IPC C10G25/03 

Abstract RU 2556861 C1

FIELD: chemistry.

SUBSTANCE: invention concerns a method for the adsorption refining of oil stock to produce capacitor oil. The oil stock is de-waxed distillate fraction recovered from waxy sulphur crude oils boiling out at temperature ranging 300-400°C. The oil stock is passed through an silica-alumina adsorbent. What is used is wide-pore uniformly porous silica-alumina having a pore space with a radius of 25-35 E, of 0.28-0.29 cm3/g, a bulk density of 0.48-0.55 g/cm3, containing at oxide basis (wt %): SiO2 - 96.15-94.65, Al2O3 - 3.5-5.

EFFECT: producing the high-quality high-yield oil, cutting the costs.
