Refining oil into motor fuels that meet modern environmental standards requires reducing the sulfur content to less than 10 ppm and improving the octane rating.
A highly efficient process of hydrotreating oil fractions can be carried out over AOK-77-25 catalyst manufactured by SKTB Katalizator. This catalyst is applicable for hydro desulfurization of diesel and kerosene fractions.
Light naphtha isomerization enables improving octane rating of motor gasoline. Pt/sulfated zirconia catalyst AOK-72-55 is intended for low-temperature isomerization of the pentane-hexane fraction.
