摘要
The invention concerns a process for producing middle distillates from an effluent produced by a Fischer-Tropsch unit, comprising optional fractionation to obtain at least one heavy fraction with an initial boiling point in the range 120-200° C., said heavy fraction or said effluent optionally being hydrotreated, then bringing it into contact with a first amorphous hydrocracking/hydroisomerization catalyst that contains at least one noble group VIII metal, the effluent obtained is distilled, then the residual fraction boiling above the middle distillates and/or a portion of the middle distillates is brought into contact with a second amorphous hydrocracking/hydroisomerization catalyst containing at least one noble group VIII metal. The invention also concerns a unit.
