METHOD OF HYDROFINING PETROLEUM FRACTIONS Russian patent published in 1997 - IPC

Abstract RU 2082749 C1

FIELD: petroleum processing. SUBSTANCE: petroleum fractions are subjected to hydrofining consisting in that raw material, at elevated temperature and pressure, is brought in contact with catalyst containing, wt.-%: nickel oxide, 2.5-4.0; molybdenum oxide, 8.0-11.0; phosphorus oxide, 0.5-1.3; and boron oxide, 0.3-1.0; and preliminarily treated successively with elemental sulfur in amount 1.0-2.5% on catalyst weight and sulfur-containing gas at 150-250 C. Method ensures residual sulfur content 0.030-0.045%. EFFECT: reduced residual sulfur content. 2 cl
