The invention relates to a method for converting a hydrocarbon feedstock, said method comprising the following steps: a) a step of visbreaking the feedstock, b) a step of separating the effluent obtained at the end of step a), c) a step of precipitating sediments in which the heavy fraction resulting from the separation step b) is brought into contact with a distillate cut, at least 20% by weight of which has a boiling point greater than or equal to 100 °C, for a period less than 500 minutes, at a temperature between 25 and 350 °C and a pressure less than 20 MPa, d) a step of physically separating sediments of the heavy fraction resulting from precipitation step c) in order to obtain said heavy fraction separated from sediments, e) a step of recovering a heavy fraction having a sediment content, measured according to the method of ISO 10307-2, less than or equal to 0.1% by weight. |
