    摘要: Process for regeneration of a catalytic moving bed in which the catalyst successively passes through at least one combustion zone A, at least one halogenation zone B, and at least one calcination zone C, whereby this process operates in a partial-regeneration-mode, the partially coked catalyst that is obtained from the last combustion zone passes into the halogenation zone in which the amount of halogen and the amount of oxygen are essentially zero--the valves of tubes (19) and (20) are then virtually closed--and the catalyst then passes through the calcination zone in which the amount of oxygen is essentially zero--the valve of tube (11) is then virtually closed.

    摘要: The invention relates to a process for the production of aromatic compounds from a hydrocarbon fraction with a catalyst that preferably circulates in a moving bed, a process that comprises at least the following successive stages that take place in at least one zone: treatment of the fraction in the presence of hydrogen and implementing at least one reaction for dehydrogenation of naphthenes; separation of the gas effluent that contains hydrogen, the liquid product and the catalyst; regeneration of the catalyst; reduction of the catalyst; and reintroduction of the catalyst for the treatment stage; recycling in the treatment stage of at least a portion of the gas effluent that contains the hydrogen that is called recycling gas; process in which the reduction stage is carried out in the presence of recycling gas that is introduced in an amount such that the amount of pure hydrogen that is provided is between 1-10 kg/kg of catalyst, whereby the effluent that is obtained from the reduction is then separated from the catalytic bed. The invention also pertains to the related device.

    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/HC2, but where (H2)1/(HC) is less than (H2)2/(HC)2. Particular application to reforming.
