Abstract

A method of reactivating an oxidation catalyst containing at least one active component selected from metals of the right-hand column of Group I, the left-hand column of Group V and VI, and Group VIII of the Periodic Table of Elements, the catalyst having been deactivated by exposure to lead-containing exhaust gases with resultant deposition of lead on the catalyst, comprises treating the catalyst with an aqueous solution of a compound of the group consisting of the polycarboxylic acids and salts thereof and the hydroxy monocarboxylic acids containing not more than 4 hydroxy groups and salts thereof, separating the treated catalyst from the solution, and drying the catalyst. The catalyst may be supported on B2O3, Al2O3, TiO2, SiO2, HfO2, Al2O3-SiO2, Al2O3-ZrO2 and Al2O3-SiO2-ZrO2. Catalytic metals specified are Pt, Pd, Ir, Rh, Fe, Co, Ni, Cr, Cu, V, W, Mo, Mn, Ag, Au and mixtures thereof, e.g. Cu-Co, Cu-Fe, Cu-Cr, Ni-Cr, Co-Cr, Mn-Cr, Mn-Fe, Pt-Fe, Pt-Co, Pt-Ni, Pd-Fe, Pd-Co, Pd-Ni, Pd-Cu, Pt-Pd, Pd-Cu-Co, Pt-Cu-Co, Cu-Co-Ni-Pd and Pt-Pd-Co. Among many organic acids listed as treating solutions the commoner are phthalic, terephthalic, oxalic, malonic, succinic, glutaric, adipic, pimelic, malic, citric, and tartaric acids. Examples are given.
