Abstract (en)
[origin: WO0247818A1] The invention relates to a hydrogenation catalyst, particularly suitable for the hydrogenation of maleic anhydride and derivatives thereof to give THF or derivatives thereof. Said hydrogenation catalyst comprises copper oxide and at least one further metal, or a compound thereof, from the group comprising Al, Si, Zn, La, Ce, elements of groups IIIA to VIIIA and groups IA and IIA, with a pore volume of >/= 0.01 ml/g for pore diameters > 50nm and a ratio of pore volume for macropores with a diameter > 50nm to the total pore volume for pores with a diameter > 4 nm of > 10 %.
