摘要

Process for conversion of a heavy hydrocarbon feedstock into at least one hydrocarbon product which has a density lower than that of the said feedstock. This process comprises the following stages: a. a treatment with a solvent for the hydrocarbon feedstock; b. a heat treatment of the oily phase obtained in stage a; c. a fractionation of the effluent resulting from the heat treatment of stage b. .
