Process for desulfurization, nitrogen-removal and / or dearomatisation of a load hydrocarbon by adsorption with an adsorbent solid use

摘要

Describes a process for purification by adsorption of a hydrocarbon feedstock, using a new adsorption agent. This adsorption agent is a spent solid adsorbent used in a first application of the catalytic treatment of hydrocarbon feeds, or adsorption, and the adsorption or catalytic performances are degraded, so that its use for the first application has become impossible. The use of this spent solid adsorbent for the purification of hydrocarbon feeds, by adsorption does not require specific treatment beforehand, in particular, no heat treatment.
