Abstract (en)
[origin: WO2019105766A1] The invention relates to a process for producing C6-C7 aromatic compounds from a naphtha-type hydrocarbon feedstock, comprising the following steps: a) sending the feedstock (1) to a first fractionation unit (2) in order to obtain an upper stream (3), which comprises C6 and C7 hydrocarbon compounds, and a lower stream (4), which comprises C8 to C10 hydrocarbon compounds; b) sending said upper stream (3) and a stream (12) comprising C6 and C7 aromatic compounds obtained at the end of step e) to an aromatics extraction unit (5) in order to obtain an aromatic base (6) and a liquid effluent (7); c) sending said liquid effluent (7) to a first catalytic reforming unit (8) to obtain a first reformate effluent (9); d) sending said first reformate effluent (9) to a reformate separation section (10) to obtain a first stream (11), which comprises C5 hydrocarbon compounds, and a second stream (12) which comprises C6 and C7 aromatic compounds; and e) recycling this second stream (12) comprising C6 and C7 aromatic compounds in step b).
