Patent number: 10793791Abstract: 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.Type: GrantFiled: July 17, 2019Date of Patent: October 6, 2020Assignee: IFP Energies NouvellesInventors: Jean-Philippe Heraud, Christophe Bouchy

Patent number: 10711206Abstract: Method for starting up a method for producing kerosene and diesel fuel from hydrocarbon compounds produced by Fischer-Tropsch synthesis. The start-up method employs catalytic reaction of Fischer-Tropsch synthesis with a synthesis gas for producing a heavy hydrocarbon fraction and a light hydrocarbon fraction, a reduction (RE) reducing a hydrotreatment catalyst by ensuring contact with a gas comprising hydrogen, bringing the heavy hydrocarbon fraction into contact with the hydrotreatment catalyst (DM). During the step for ensuring contact, the temperature (TEMP) of the catalyst is increased to a temperature of between 260° C. and 360° C. Then, (TR) bringing a mixture comprising the heavy hydrocarbon fraction and the light hydrocarbon fraction into contact with the hydrotreatment catalyst is carried out.Type: GrantFiled: October 24, 2018Date of Patent: July 14, 2020Assignee: IFP Energies NouvellesInventors: Hugues Dulot, Aline Grezaud, Jean-Philippe Heraud
