Beschreibung
Zusammenfassung:	FIELD: petroleum processing. ^ SUBSTANCE: invention, in particular, relates to petroleum fraction hydrofining process utilizing presulfided catalysts. Hydrofining process is described involving contacting petroleum fractions with presulfided catalyst containing alumina-carried cobalt, molybdenum, phosphorus, and boron, said process being conducted at 320-340°C, pressure 3.0-5.0 MPa, volumetric feed supply rate 1.0-6.0 h-1, normalized volumetric hydrogen-containing gas-to-feed ratio (500-1000):1 in presence of catalyst sulfided outside of reactor. Sulfidizing of catalyst is accomplished with hydrogen sulfide at 80-500°C and volumetric hydrogen sulfide flow rate 0.02-6.0 h-1. Chemical composition of catalyst is the following, wt %: MoS2 8.0-17.0, Co3S2 1.5-4.0, P2O3 2.5-5.0, B2O3 0.3-1.0, La2O3 1.0-5.0, and aluminum oxide - the balance. ^ EFFECT: simplified process. ^ 2 cl, 1 tbl, 3 ex
