    Abstract: A carrier-supported catalyst is made by applying one or more non-noble metal and noble metal components on to a ceramic honeycomb structure coated with a layer of a heat-resistant metal oxide. To this end, the ceramic honeycomb structure is dipped at least once into an aqueous suspension of pseudoboehmite and zirconium oxide hydrate, the honeycomb structure so treated is dried at temperatures of up to 250 DEG C. and calcined at temperatures of up to 1000 DEG C.; next, the honeycomb structure is impregnated with an aqueous solution of at least one iron salt, and, if desired, nickel and cerium salts, dried at temperatures of up to 250 DEG C. and annealed at temperatures of up to 600 DEG C.; next, the honeycomb structure is impregnated with an aqueous solution containing at least one soluble compound of platinum, rhodium or palladium, and, if desired cerium, one of the solutions under (b) or (c) being required to contain cerium; the honeycomb structure so treated is ultimately dried at temperatures of up to 250 DEG C. and annealed at temperatures of up to 600 DEG C.

    Abstract: A carrier-supported catalyst is prepared by applying a noble metal on to a ceramic honeycomb structure coated with an aluminum oxide layer. To this end, the ceramic honeycomb structure is impregnated with an aqueous solution containing nitrilotriacetic acid or ethylenediaminotetraacetic acid, ammonia and at least one noble metal compound.

    Abstract: PROCESS FOR MAKING ACETIC ANHYDRIDE The disclosure relates to a process for making acetic anhydride by reacting methyl acetate and/or dimethylether with carbon monoxide, which may be used in admixture with up to 30 volume % hydrogen, under practically anhydrous conditions at temperatures of 390 to 540 K, under pressures of 1 to 300 bars in the presence of a catalyst system containing nickel or nickel compounds, iodine and/or its compounds as well as a tertiary or quaternary organic nitrogen, phosphorus, arsenic or antimony compound. More particularly a catalyst system is used which contains vanadium or niobium or a compound thereof as an additional constituent.
