Abstract
The invention relates to a process for the production of C6-C7 aromatic compounds from a hydrocarbon feedstock of naphtha type comprising a step of fractionating (2) the feedstock in order to obtain an upper stream and a lower stream, a step of catalytic reforming of the upper stream (6) and of the lower stream (9), a step of recombining (15) the reformate effluents obtained, a step of recontacting (16) and a step of stabilizing (19) the stabilized reformate effluents and a step of separating (22) the raffinate in order to recover C6 and C7 hydrocarbon compounds.
