Claim:
1. A process for purifying a hydrocarbon feed comprising impurities, in which the following steps are carried out simultaneously: a) treating the hydrocarbon feed in the liquid phase in a first adsorption unit comprising a first and a second adsorption column ( b) treating a secondary liquid hydrocarbon feed, which is constituted either by a fraction of the hydrocarbon feed or by a fraction of the hydrocarbon effluent depleted in impurities from step a), in a second adsorption unit, and a treated secondary liquid hydrocarbon feed is taken off from said second adsorption unit; c) heating the treated secondary liquid hydrocarbon feed obtained from step b) to a temperature of from 100 to 350° C.; d) regenerating the second adsorbent solid of the second adsorption column (
