摘要
A moving bed process for producing aromatic compounds comprises at least a first step in which principally naphthene dehydrogenation is carried out in the presence of hydrogen in a mole ratio (H2)1/(HC), said step being followed by at least one subsequent step carried out at a mole ratio (H2)2/(HC)2, the process also comprising reducing the catalyst with hydrogen in a ratio (H2)red/(HC). In accordance with the invention, (H2)1/(HC)+(H2)red/(HC)=(H2)2/(HC)2, (HC) representing the molar quantity of feed in the first step and (HC)2 that of the subsequent step, or (H2)1/(HC)+(H2)red/(HC)(H2)2/(HC)2, but where (H2)1/(HC) is less than (H2)2/(HC)2. Particular application to reforming.
