FIELD: gasoline production. SUBSTANCE: invention is concerned with distillates containing, along with sulfur compounds, unsaturated and aromatic hydrocarbons. Distillates are preliminarily brought in contact with alumina at 50-160 C taken in amount 5-30% based on total volume of hydrogenation catalyst charge. Thereafter, two-step hydrogenation is carried out in presence of alumina-cobalt-molybdenum catalyst at 200-280 C in the first step and 260-380 C in the second step, reaction pressure being 3-5 MPa and raw material volume velocity 0.5-3.0 hin both steps. EFFECT: enhanced efficiency of process. |
