FIELD: production of diesel fuel; oil processing industry. SUBSTANCE: hydrogenation treatment of origin oil raw materials is carried out in three steps on various catalysts, the process is carried out in aggregate contour, pressure of hydrogen in reaction zone being 3.0-4.8 MPa. Quantities of hydrogenation catalyst, hydrorefining catalyst and catalyst of destruction dearomatization are 30-65 %, 10-25 % and 25-45 % respectively. Proposed method makes possible to produce ecologically pure diesel fuel. EFFECT: improved quality of desired product. 4 cl
