A shaped catalyst composition comprises (i) at least one metal selected from nickel, manganese, zinc, cobalt and iron, (ii) calcium silicate, and (iii) at least one clay material. The shaped catalyst may be produced by preparing a paste comprising the components (i), (ii) and (iii), and at least one solvent; forming a shaped particle from said paste; and drying and calcining said shaped particle. The catalyst composition may be employed in the hydrogenation of aldehydes, ketones, carboxylic acids, carboxylic acid esters and nitroaromatic compounds. |
