Patent ID: 7976698

Claim:
A process for catalytic regenerative reforming of a distillation gasoline or cracking gasoline in the presence of hydrogen and comprising regeneration of the catalyst, said regeneration comprising reducing said catalyst with at least part of the hydrogen used in reforming of said gasoline thereby producing a reduced catalyst and a gaseous effluent, wherein prior to the reduction of the catalyst with said hydrogen-containing gas, the latter gas is purified by removing C2+ hydrocarbons in a purification unit by adsorption that employs adsorbent masses, such that the content of the C2+ compounds in gas exiting the purification unit is between 0.5 mol % and 1 mol %, said adsorbent masses being regenerated, in a temperature swing adsorption unit, at a temperature of 220° to 280° C. and a pressure of 0.5 to 2.5 MPa, by an increase in temperature obtained from at least a portion of the gaseous effluent produced from reducing the catalyst with hydrogen-containing gas.
