Abstract: A CATALYTIC ARTICLE COMPOSED OF A CATALYST SUPPORT AND AN ADHERENT CATALYTICALLY ACTIVE LAYER OF A CRYSTALLINE MATERIAL HAVING A COMPOSITION EXPRESS IN TERMS OF OXIDES AS FOLLOWS: (CU0) X (AL203)Y .NH20 WHERE X IS FROM 1 TO 3 AND Y IS FROM 1 TO 4. THE NOVEL ARTICLE IS PREPARED BY CONTACTING A SUPPORT WITH A SORUCE OF ALUMINUM, A BASE, A SOURCE OF COPPER AND AN AMMONICAL REAGENT WHERE THE REAGENT AND COPPER ARE PRESENT IN THE RATIO OF NH3 TO CU OF AT LEAST FOUR. THE CATALYTIC ARTICLE FINDS APPLICATION IN SUCH PROCESSES AS THE OXIDATION OF OLEFINS, INCORPORATION INTO CATALYTIC MUFFERS FOR THE OXIDATION OF EXHAUST GASES, IN OXYHALOGENATION REACTIONS AND FOR THE CONVERSION OF SO2 TO SO3 IN FLUE GASES.
