METHOD FOR PRODUCING AROMATIC COMPOUNDS IN MOBILE BED COMPRISING CATALYST REDUCTION

摘要

The invention concerns a method for producing aromatic compounds in catalyst mobile bed comprising at least a first step which essentially consists in the dehydrogenation of naphthenes in the presence of hydrogen in a molar ratio (H2)1/HC, followed by at least a subsequent step performed with a molar ratio (H2)2/(HC)2; the method further comprises catalyst reduction by hydrogen in a ratio (H2)Red/(HC), and the invention is characterised in that (H2)1/(HC) + (HC)Red/(HC) (H2)2/(HC)2 but with (H2)1/(HC) less than (H2)2/(HC)2. The invention is useful in particular for reforming.
