Abstract
A batch process for carrying out a hydrogenation reaction comprises mixing a pyrophoric catalyst with reactants and solvents to form a reaction mixture in a reaction vessel. Hydrogen is added to the reaction vessel. After hydrogenation, the desired hydrogenation product is removed from the reaction vessel and the pyrophoric catalyst-rich material from the reaction vessel is delivered to a pressure filter. Water is added to the pyrophoric catalyst-rich material in the filter and the spent pyrophoric material is removed from the pressure filter in a water wet form.
