    摘要： Process for the production of middle distillates from a paraffinic feedstock produced by Fischer-Tropsch synthesis comprising at least one light fraction, known as condensate, and a heavy fraction, known as waxes, in which: the said light fraction is stored in a vessel (B) maintained under an inert atmosphere and in which the temperature inside the vessel is maintained at a value of less than 20° C.; the said heavy fraction is stored in a vessel (C) maintained under an inert atmosphere and in which the temperature inside the vessel is maintained at a value of between 80 and 230° C.

    摘要： A process is described for producing middle distillates from a paraffinic feedstock produced by Fischer-Tropsch synthesis and divided into a light fraction (cold condensate) and a heavy fraction (waxes). The process involves fractionation of the waxes to obtain a light fraction, the final boiling point of which is between 350° C. and 400° C., and a heavy fraction which boils above the light fraction. The light fraction is mixed with at least one portion of the cold condensate. The resultant mixture is hydrotreated in the presence of a hydrotreatment catalyst of at least one portion of the resultant effluent is hydroisomerized in the presence of a catalyst comprising at least one noble metal from Group VIII and at least one zeolite IZM-2. At least one portion of the heavy fraction is subjected to hydrocracking and hydroisomerization in the presence of a hydrocracking catalyst. The resultant effluents are fractionated to obtain at least one middle distillates fraction.

    摘要： Process for the production of olefins and of middle distillates from a paraffinic feedstock, in which: a) a paraffinic feedstock resulting from a Fischer-Tropsch unit is recovered, the said feedstock containing a light fraction and a heavy fraction; b) the light fraction is sent to a catalytic cracking unit; c) the effluent resulting from the catalytic cracking unit is separated in a fractionation unit in order to obtain a fraction of light hydrocarbons, an olefinic fraction and a residual liquid fraction; d) the heavy fraction is sent to a hydrocracking/hydroisomerization unit; e) the effluent resulting from the hydrocracking/hydroisomerization unit is separated in a fractionation unit in order to obtain a middle distillates fraction, a naphtha cut having a maximum boiling point of less than 180° C. and an unconverted heavy fraction; f) a part of the naphtha cut resulting from the fractionation unit is sent to the catalytic cracking unit.
