    摘要: A process for catalytic reforming and for producing aromatics is carried out in the presence of a catalyst comprising at least one support, at least one metal from group VIII of the periodic table and at least one additional element M selected from the group formed by germanium, tin, lead, rhenium, gallium, indium, and thallium. The process is characterized in that the catalyst is prepared using a process in which said metal M is introduced in an aqueous solvent in the form of at least one organometallic compound comprising at least one carbon-M bond.

    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.

    摘要: The invention concerns a process for isomerizing a feed containing essentially hydrocarbons, preferably paraffins containing principally 4 to 8, preferably principally 4 to 6 and more preferably principally 5 and/or 6 carbon atoms per molecule, comprising a fractionation zone and at least two isomerization reaction zones, said process comprising carrying out the following steps: (1) sending the feed to a fractionation zone; (2) drawing off at least a portion of the liquid circulating in said zone, via at least two draw-off levels; (3) sending the major portion of the liquid drawn off in step (2) to at least two isomerization zones, each isomerization zone being associated with a draw-off level; (4) sending the major portion of the effluents from step (3) to the fractionation zone, substantially adjacent to the draw-off levels; (5) recovering an effluent from the fractionation zone.
