FIELD: petroleum chemistry. SUBSTANCE: oil is distilled over to run off kerosene of 120-260 C fraction and diesel fuel of 160-320 and 240-360 C fractions. Diesel fractions are mixed. One part is distilled over to run off 200-320 C fraction. The last and remaining parts of mixture are subjected to hydrofining. 200-320 C hydrofined fraction is dewaxed with the aid of zeolite to produce dewaxed fraction. Kerosene fraction is subjected to secondary distillation to obtain NK-240 and last fractions. Winter-grade diesel fuel is produced by mixing dewaxed fraction and mixture of diesel fractions or the last fraction subjected to hydrofining, kerosene and last fraction with the following amount of components: 10.0-20.0; 20.0-50.0; 30.0-50.0; the balance, last fraction. EFFECT: higher efficiency. 1 dwg, 3 tbl
