The invention concerns an FCC pretreatment method by soft hydrocracking of a hydrocarbon feedstock comprising a distillate fraction under vacuum or a deasphalted oil or a mixture of those two fractions, called main feedstock, to produce diesel oil and an effluent having an initial boiling point higher than 320 °C, said effluent (FCC feedstock) being then subjected to a catalytic cracking; method whereby at least 85 wt. % of said main feedstock boils above 375 °C and at least 95 wt. % of said main feedstock boils below 650 °C, the soft hydrocracking being carried out under an absolute pressure of 2 to 12 MPa's and at a temperature ranging between 300 and 500 °C. Said method is characterized in that the hydrocarbon feedstock further comprises a lighter hydrocarbon fraction, called secondary feedstock, whereof at least 50 wt. % boils below 375 °C and at least 80 wt. % boils above 200 °C.

L'invention concerne un procédé de pré-traitement de FCC par hydrocraquage doux d'une charge hydrocarbonée comprenant une coupe distillât sous vide ou une huile désasphaltée ou bien un mélange de ces deux fractions, dite charge principale, pour produire du gazole et un effluent ayant un point initial d'ébullition supérieur à 320~C, ledit effluent (charge de FCC) étant ensuite soumis à un craquage catalytique, procédé dans lequel 85% poids au moins de ladite charge principale bout au dessus de 375oC et au moins 95% poids de ladite charge principale bout en dessous de 650oC, l'hydrocraquage doux étant opéré sous une pression absolue de 2 à 12 MPa et à une température comprise entre 300 et 500~C, caractérisé en ce que la charge hydrocarbonée comprend également une coupe plus légère d'hydrocarbures, dite charge secondaire, dont au moins 50% poids bout en dessous de 375~C et au moins 80% bout au dessus de 200oC.
