Heterogeneously catalyzed three‐phase reactions are often transport limited, thus, resulting in reduced reaction rates. The limited transport of the gas through the liquid phase to the active center is commonly solved by running the reaction at high pressure and intensive stirring. The authors present a membrane reactor using a new microporous catalytic membrane to directly supply the catalyst with H 2 avoiding the liquid phase.
