Beschreibung
Zusammenfassung:	A process for making a catalytic rare earth metal oxide-coated microporous particulate material that has the rare earth metal oxide coated on outer surfaces of the microporous particulate material. The process comprises the steps of: i) combining an amount of a colloidal dispersion of rare earth metal oxide hydrate with a compatible microporous particulate material to form a slurry, the microporous particulate material having an average pore size less than the particle size of the colloidal dispersion, to position thereby, the colloidal dispersion on the outer surfaces of the microporous particulate material; and ii) heat treating the slurry to fix the rare earth metal oxide to the outer surfaces of the microporous particulate material.
