Abstract:
1. A method of treatment of a hydrocarbon charge containing at least 95 wt. % of compounds having a boiling point of at least 340° C., said method comprising the following stages: a) contacting the charge with a solvent in order to obtain a deasphalted effluent having a content of asphaltenes (insoluble in n-heptane according to standard NF-T-60-115) below 3000 ppm by weight, and containing components boiling above 500° C., b) subjecting the entirety of the deasphalted effluent from stage a) to cracking in the presence of hydrogen and a hydrocracking catalyst, in a bubbling-bed reactor, so as to convert at least 50 wt. % of the fraction of the deasphalted effluent boiling above 500° C. to compounds having a boiling point below 500° C., c) fractionating the effluent from stage b) to recover gasolines, kerosene, gas oils and a first residue, and d) cracking at least a portion of said first residue catalytically so as to obtain an effluent comprising gasolines, kerosene, gas oils and a second residue.
