METHOD FOR CONVERTING PETROLEUM LOADS COMPRISING A VISCOREDUCTION STEP, A MATURATION STEP AND A SEDIMENT SEPARATION STEP FOR THE PRODUCTION OF LOW SEDIMENT FOLDS

摘要

The invention relates to a process for converting a hydrocarbon feedstock containing at least one hydrocarbon fraction having a sulfur content of at least 0.1% by weight, an initial boiling point of at least 340.degree. a final boiling temperature of at least 440 ° C to obtain a heavy fraction having a sediment content after aging less than or equal to 0.1% by weight, said process comprising the following steps: a) a step of visbreaking of the feedstock in at least one maturation chamber, b) a step of separating the effluent obtained at the end of step a), c) a step of maturation of the heavy fraction resulting from step b d) a step of separating the sediments from the heavy fraction resulting from the curing step c) to obtain said crude fraction.
