Abstract
Process for catalytic conversion in the presence of hydrogen with regeneration of the catalyst that comprises a stage for reduction of said catalyst by the hydrogen that is obtained from the catalytic conversion stage, whereby this hydrogen is purified in advance of impurities that it contains by running it over adsorbent masses, whereby said adsorbent masses are regenerated by an increase in temperature that is provided by the effluent from the reduction stage of the catalyst. Application to the processes for regenerative reforming or dehydrogenation of paraffins and naphthenes and most generally to any moving-bed process that operates in the presence of hydrogen.
