The objective of this review article is to provide students and young researchers in the field, with a general but relatively short overview of the current state of the art in zeolite membranes. It will cover zeolite membrane preparation, characterization and main applications, while referring to the recent literature. For more detailed reviews, the lecturer will refer to a 

One of the first zeolite based membranes were composite membranes, obtained by dispersion of zeolite crystals in dense polymeric films in order to make zeolite filled polymeric membranes [59,60,61], These membranes have been developed at the end of the 80 s for both gas separation and pervaporation. The clogging of zeolite pores by the matrix and the quality of the interface between the zeolite crystals and the polymer matrix (non-selective diffusion pathways) were key points.
