84 results about "Heterogeneous catalysis" patented technology

Heterogeneous catalysis is the type of catalysis where the phase of the catalyst differs from the phase of the reactants or products. Contrasts with homogeneous catalysis where the reactants, products and catalyst exist in the same phase. Phase distinguishes between not only solid, liquid, and gas components, but also immiscible mixtures (e.g. oil and water), or anywhere an interface is present. Catalysts are useful because they increase the rate of a reaction without themselves being consumed and are therefore reusable.
