This overview discusses some of the developments and outstanding opportunit
ies in the field of catalytic reactors based on porous ceramic membranes, b
oth inert and catalytic. This is an emerging area, where inputs from hetero
geneous catalysis, material science and reactor engineering are playing the
key roles. Rather than attempting a thorough review of the relevant litera
ture, this work deals with some general concepts and then concentrates on a
few selected examples that illustrate the application of membrane reactors
