New process for regenerating a used catalyst with an aqueous solution of hydrogen peroxide stabilized by an organic compound.

摘要

SE describes a process for regenerating a catalyst containing at least one metal contaminant from the group vanadium, nickel and iron and a composition USED in the process. THE CATALYST FROM AN AREA OF HYDROCARBONS divests hydroconversion in a zone (1), and then introduced into a BED REACTOR EFERVESCENTE (3) in the presence of hydrogen peroxide introduced by a pipe (4). EXTRACTION SOLUTION IS diverted via line (5). APPLICATION OF REGENERATION IN PARTICULAR CATALYSTS USED hydrotreating the petroleum industry.
