FIELD: engines and pumps. n SUBSTANCE: invention relates to production of fuel for jet engines from kerosene stock. Proposed method comprises hydrofining of kerosene stock with freezing point interval of 163-302°C (325-575°F) over hydrofining catalyst under conditions of hydrofining. This allows getting hydrofined kerosene stock. Besides, it includes dewaxing of, in fact, all hydrofined kerosene stock over catalyst including 1-D molecular sieve with ten rings under conditions of dewaxing to get water-dewaxed kerosene stock. Also, it includes fractionating of water-dewaxed kerosene stock to get fuel for jet engines. n EFFECT: higher yield, better properties. n 10 cl, 1 dwg, 2 tbl, 1 ex |
