Abstract: Process for the production of C6-C7 aromatic compounds from a hydrocarbon feedstock of naphtha type comprising the following stages: a) the said feedstock (1) is sent into a first fractionation unit (2) in order to obtain an upper stream (3) comprising C6 and C7 hydrocarbon compounds and a lower stream (4) comprising C8 to C10 hydrocarbon compounds; b) the upper stream (3) and a stream (12) comprising C6 and C7 aromatic compounds obtained on conclusion of stage e) are sent into a unit for extraction of the aromatics (5) in order to obtain an aromatic base (6) and a liquid effluent (7); c) the liquid effluent (7) is sent into a first catalytic reforming unit (8) in order to obtain a first reformate effluent (9); d) the said first reformate effluent (9) is sent into a reformate separation section (10) in order to obtain a first stream (11) comprising C5 hydrocarbon compounds and a second stream (12) comprising C6 and C7 aromatic compounds; e) the second stream (12) comprising C6 and C7 aromatic compounds is recycled in stage b).

Abstract: The invention relates to a process for catalytic reforming of a naphtha hydrocarbon feedstock using a number of reaction zones in series, wherein the reaction zones contain a reforming catalyst bed. The process comprises comprising the following stages: sending hydrocarbon feedstock that is heated with hydrogen through the reaction zones to convert paraffinic and naphthenic compounds into aromatic compounds, with the effluent that is produced by each reaction zone, except for the last reaction zone, being heated before its introduction into the following reaction zone; drawing off a reformate from the last reaction zone.

Abstract: The present invention concerns a radial bed reactor comprising a vessel provided with a reaction zone with a moving catalyst bed. The reactor further comprises, inside the reaction zone: at least two feed distribution tubes, each having a first end in communication with the feed inlet means and a second, closed end, the distribution tubes extending in a substantially vertical manner and being designed to allow the feed to pass through the reaction zone and to retain the catalysts; and at least two effluent collection tubes, each having a first end (14) communicating with the effluent outlet means and a second, closed end (15), the collection tubes extending in a substantially vertical manner and being designed to allow effluent to pass through the collection tube and to retain the catalysts.
