Recycle systems can be implemented through various methods, including: 1. Homogeneous Catalysis: Involves catalysts dissolved in the same phase as the reactants. Recycling often requires separating the catalyst from the product mixture, which can be achieved through techniques like distillation or extraction. 2. Heterogeneous Catalysis: Involves catalysts in a different phase than the reactants, typically solids. Recycling is simpler as the catalyst can be filtered out and reused directly after regeneration. 3. Enzyme Catalysis: Enzymes can be immobilized on supports, allowing them to be reused multiple times without significant loss of activity.
