Abstract
The invention concerns a process for the intense conversion of a heavy hydrocarbon feed, comprising the following steps: a) a first step for ebullated bed hydroconversion; b) a step for separating at least a portion of the hydroconverted liquid effluent obtained from step a); c) a step for hydrocracking at least a portion of the vacuum gas oil fraction obtained from step b); d) a step for fractionating at least a portion of the effluent obtained from step c); e) a step for recycling at least a portion of the unconverted vacuum gas oil fraction obtained from step d) to said first hydroconversion step a).
