<DIV>Membrane reactors are increasingly replacing conventional separation, process and conversion technologies across a wide range of applications. Exploiting advanced membrane materials, they offer enhanced efficiency, are very adaptable and have great economic potential. There has therefore been increasing interest in membrane reactors from both the scientific and industrial communities, stimulating research and development.<BR><BR>Volume 1 explores fundamental materials science, design and optimization, beginning with a consideration of polymeric, dense metallic and composite membranes for membrane reactors, such as polymeric and nanocomposite membranes for membrane reactors, inorganic membrane reactors for hydrogen production, palladium-based composite membranes and alternatives to palladium-based membranes for hydrogen separation in membrane reactors. Following sections investigate zeolite, ceramic and carbon membranes and catalysts for membrane reactors and explore membrane reactor modeling, simulation and optimization, including use of mathematical modeling, computational fluid dynamics (CFD), artificial neural networks and non-equilibrium thermodynamics to analyze varied aspects of membrane reactor design and production enhancement.</div>
