Claim:
1. A process for the intense conversion of a heavy hydrocarbon feed, comprising the following steps: a) a first step for ebullated bed hydroconversion of the feed in the presence of hydrogen, comprising at least one three-phase reactor containing at least one ebullated bed hydroconversion catalyst; b) a step for separating at least a portion of the hydroconverted liquid effluent obtained from step a) into a gasoline fraction, a gas oil fraction, a vacuum gas oil fraction and an unconverted residual fraction; c) i) either a step for hydrotreatment of at least a portion of the gas oil fraction and the vacuum gas oil fraction obtained from step b) in a reactor comprising at least one fixed bed hydrotreatment catalyst; d) a step for fractionating at least a portion of the effluent obtained from step c)i) or step c)ii) into a gasoline fraction, a gas oil fraction and an unconverted vacuum gas oil fraction; e) a step for recycling at least a portion of the unconverted vacuum gas oil fraction obtained from fractionation step d) to said first hydroconversion step a); f) a second step for hydrocracking at least a portion of the gas oil fraction obtained from fractionation step d); g) a step for recycling all or a portion of the effluent obtained from step f) to the fractionation step d).
