Claims18
A process for preparing alcohols comprising reacting carboxylic acids and/or carboxylic esters with hydrogen in the presence of a catalyst;
- wherein the catalyst is in a non-reduced state and comprises 20 to 80% by weight of CuO, 10 to 80% by weight of ZnO and 1 to 50% by weight of Al2O3, and has a pore size distribution in which 5 to 15% of the total pore volume is in the pore diameter range of less than 150 Å and 80 to 95% of the total pore volume is in the pore diameter range of greater than 250 Å.
