Abstract

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.
