  • Patent number: 7658836
    Abstract: The process of producing middle distillates from effluents obtained by a Fischer-Tropsch synthesis, comprises a step for hydro-treatment and purification and/or decontamination by passage over a multi-functional guard bed prior to a step of hydrocracking/hydroisomerization.

  • Patent number: 7427348
    Abstract: A process with an increased efficiency for the preparation of middle distillates with excellent properties at low temperatures and substantially without oxygenated organic compounds, starting from a synthetic mixture of hydrocarbons at least partly waxy, containing a fraction of alcohols, comprising the separation of the mixture into a low-boiling fraction and a high-boiling fraction; the subsequent hydrogenation of the low-boiling fraction under such conditions as to avoid any substantial variation in its average molecular weight; the joining of at least a part of the hydrogenated fraction with said high-boiling fraction, and the subsequent catalytic hydrocracking treatment of the mixture of hydrocarbons thug formed, to obtain a substantial conversion of the waxy part into middle distillate.
