(57) Abstract
The present invention relates to a process for the conversion of a hydrocarbon fraction comprising a step a) for
treating a hydrocarbon charge in the presence of a hydrogen in at least one reactor containing at least one
hydrodesulphurisation catalyst in a fixed bed under conditions that make it possible to obtain a liquid effluent with a
reduced sulphur content, a step) for treating at least a part - of the liquid effluent originating from step a) in the
presence of hydrogen in at least one three-phase reactor, containing at least one hydrotreatment catalyst in a boiling
bed, operating with an ascending stream of liquid and gas, said reactor comprising at least one means of withdrawing
the catalyst from said reactor situated near the bottom of the reactor and at least one means of making up fresh
catalyst in said reactor situated near the top of said reactor, and a step c) in which at least part of the product obtained
in step b) is passed to a distillation zone from which are recovered a gas fraction, a motor fuel fraction of the petrol
type, a motor fuel fraction of the diesel type, and a liquid fraction which is heavier than the diesel type fraction. This
process may also contain a step d) for the catalyst cracking of the heavy fraction obtained in step c).
