Abstract
A process is disclosed for continuously hydrogenating unsaturated fats, fatty acids or fatty acid esters on a shaped catalyst in a solid bed. The reactants flow over the catalyst in the presence of a medium or solvent mixture in supercritical conditions. This leads to considerably improved activity and selectivity of the hydrogenation reaction compared with conventional trickle bed hydrogenation processes.
