The basic working principle of a membrane reactor involves the integration of a catalytic bed with a membrane module. The reactants are fed into the reactor, where they encounter the catalyst that promotes the desired chemical reaction. Simultaneously, the membrane selectively separates the reaction products from the unreacted species. This can drive the reaction equilibrium towards the products, enhancing the overall yield. The membranes used can be either inorganic or organic, depending on the specific application and operating conditions.
