Method of production of fuel in the water has a low sulphur content from a cut from catalytic cracking hydrocarbon slurry type, and which has a step for the hydrotreatment specific .

摘要

The present invention describes a process for the production of fuel in the water from a hydrocarbon cut from a catalytic cracking unit, called "slurry " section of the sulfur content of greater than 0,5% by weight, and containing at least 80% of compounds having a boiling temperature of at least 360°C, and a final temperature of the boiling point of at least 520°C, said method comprising: a) a step of filtration of the section" slurry ", so as to eliminate at least a portion of the fine particles that it contains, b) a hydrotreatment step of producing a hydrotreated effluent, c) a step of separation of the hydrotreated effluent from step (b) in order to obtain at least one gaseous fraction and a liquid hydrocarbon fraction, said liquid fraction of the fuel required.
