Several methods are employed for catalyst recovery, including:
Filtration: Useful for solid catalysts in heterogeneous catalysis. The catalyst particles are separated from the reaction mixture by mechanical means. Centrifugation: Also used for solid catalysts, where centrifugal force helps in separating the catalyst from the reaction mixture. Precipitation: Involves converting the catalyst into an insoluble form that can be filtered out of the reaction mixture. Distillation: Applied primarily in homogeneous catalysis where volatile components are separated, leaving behind the catalyst.
