Despite extensive investigation of zeolites beds and membranes, many aspects of separation using zeolites are not yet well understood. There is a pressing need to state general principles of size and shape selective separations. This work collates important experimental, theoretical and simulation contributions to size and shape selectivity. We review aspects that are well understood, highlight conflicting ideas that have been proposed, and identify aspects that have yet to be addressed adequately.
