Abstract
For conversion of crude oil or a heavy hydrocarbon fraction having an initial boiling point of at least 300° C., conducting a catalytic hydroconversion in a three-phase reactor operating in a boiling bed with an upward flow of liquid and gas, separating resultant effluent into a light liquid fraction boiling at less than 300° C. and a heavy liquid fraction boiling above 300° C., deasphalting the heavy liquid fraction to obtain a deasphalted hydrocarbon fraction and residual asphalt, and recycling at least one portion of the deasphalted hydrocarbon fraction upstream of the hydroconversion stage.
