    摘要： The invention concerns a process for producing middle distillates from effluents obtained from the Fischer-Tropsch process, comprising separating a heavy cut with an initial boiling point of 120-200° C., hydrotreating said cut and fractionating the hydrotreated cut to obtain at least one intermediate fraction and at least one fraction that is heavier than the intermediate fraction. The intermediate fraction boils between T1 and T2, T1 being in the range 120-200° C. and T2 being in the range 300-410° C. The heavy and intermediate fractions are treated over a hydrocracking/hydroisomerisation catalyst and the effluents obtained are distilled. The invention also concerns a unit.

    摘要翻译： 本发明涉及从费 - 托方法得到的流出物生产中间馏分的方法，包括分离初馏点为120-200℃的重馏分，加氢处理所述馏分并分馏加氢处理的馏分以获得至少一种 中间馏分和至少一个比中间馏分重的馏分。 中间馏分在T 1和T 2之间沸腾，T 1在120-200℃的范围内，T 2在300-410℃的范围内。重质和中间馏分经加氢裂化/加氢异构化催化剂处理， 所得的流出液被蒸馏。 本发明还涉及一个单元。
