<p>The invention relates to a process for preparing a Diesel fuel component by hydrocracking the starting material at medium pressure by using a catalytic system consisting of two catalysts placed in a reactor provided with a distribution tray for the gas-liquid phases, at temperatures of 360...450 C, preferably 380...410 C, at volume flow rates of 0.5...3 h^(-1), preferably 0.8...1.5 h^(-1), at a H2/starting material ratio of 1000...2000 Nm3/m3, preferably 1200...1700 Nm3/m3 and at a pressure of 100...150 bars, preferably 110...130 bars, the fuel preparing yield being of at least 50%, said fuel having the following characteristics: a sulphur content of 150 ppm at the most, a flow point<-15 C and a polycyclic hydrocarbon content of 5% at the most.</p> |
