Copper oxide 10 - 90 mass and 10 - 90 mass to contain the oxide of the metal of 1 genera or several

摘要

This invention, the catalyst copper oxide 5 - 100 mass %, profitably 40 - 90 mass %, and Al, Si, Zn, La and Ce, 0 - 95 mass %, 10 - 60 mass % contains the metal or these chemical compounds of the element to VIIIA family and 1 kinds or several kinds from group which consists of the element of IA family and IIA family profitably from IIIA family as an active material, at the same time these materials on the inactive carrier material feature that it has taken part in the form of the thin layer, C₄ - di-carboxylic acid and/or thatThe derivative, profitably it regards the catalyst in order to hydrogenate the maleic anhydride in the vapor phase.
