    摘要: Process for regenerating or activating a catalyst for isomerizing n-paraffins, containing at least one group VIII metal supported on an acid mordenite, wherein, after having lost at least a part of its initial activity, said catalyst is treated in a first step with an oxygen-containing gas at a temperature lower than about 550.degree. C., so as to remove the major part of the catalyst coke content, and in a second step the resultant product from the first step is oxychlorinated to a temperature of about 200.degree.-500.degree. C. by means of a gas mixture containing oxygen, water and chlorine or at least one chlorinated compound, said chlorine or chlorinated compound being used in a total amount of 0.5-10% by weight, calculated as chlorine, in proportion to the mordenite weight.

    摘要: The present invention relates to a process and a reactor for low pressure catalytic reforming of gasolines with heating by smoke gases.The reactor of the invention comprises:at least one means for introducing and removing the charge,at least one means for introducing and removing the catalyst,at least two elementary reaction cells not adjacent each other, substantially vertical and parallelepipedic, substantially parallel to each other, each of said cells being formed of three substantially parallelepipedic enclosures (an individual charge distributor, an individual processed charge collector, a catalytic bed),at least one general charge distributor,at least one general processed charge collector.The reforming process of the invention may be used in this reactor, smokes-based heating gases, coming from the combustion in air of a hydrocarbon mixture, flowing between the elementary reaction cells and thus bringing the heat required for the reforming reaction.
