CATALYSTS FOR MAKING ETHYL ACETATE FROM ACETIC ACID

摘要

Catalysts and processes for making catalysts suitable for use in processes for hydrogenating acetic acid to form of ethyl acetate and mixtures of ethyl acetate and ethanol. In a first embodiment, the catalyst includes a high loading of nickel, palladium or platinum. In a second embodiment, the catalyst comprises a first metal selected from nickel and palladium and a second metal selected from tin and zinc. In a third embodiment, the catalyst comprises one or more metals on a support that has been modified with an acidic support modifier or a redox support modifier.
