FIELD: chemistry.SUBSTANCE: invention creates a method of producing ecologically safe marine low-viscous fuel, which includes atmospheric-vacuum distillation of oil with extraction of fractions, hydrogenetive refining, catalytic cracking, compounding fractions introduction of additive into the produced mixture, upon that for atmospheric-vacuum distillation it is given vacuum gas oil fraction 240-560 °C, which is subjected to hydrogenetive refining through sulfided alumina-cobalt-molybdenum catalyst with fractionation of diesel fuel 216-358 °C and hydrogenetive refined vacuum gas oil 325-548 °C (GOVG), with subsequent catalytic cracking light gas oil fraction and separating GOVG catalytic cracking of 219-357 °C; then one performs compounding fractions of diesel fuel, fraction, GOVG and light gas oil of catalytic cracking at a ratio of 75-83:2-6:15-19 %, respectively, introduction of a compressing-dispersing additive in amount of 0.06 wt%.EFFECT: present method allows to obtain marine fuel, which satisfies the demands of normative documents.1 cl, 5 dwg |
