摘要： A process for purification by adsorption of a hydrocarbon feedstock that uses a novel adsorption agent is described. This adsorption agent is a spent solid adsorbent that has been used in a first application of catalytic treatment of hydrocarbon feedstocks, or of adsorption, and whose adsorption or catalytic performance levels are degraded such that its use for the first application has become impossible. The use of this spent solid adsorbent for the purification of hydrocarbon feedstocks by adsorption does not require specific treatment in advance, in particular not heat treatment.
