Mechanical and pore characteristics of zeolite composite membranes

Abstract

All-inorganic membranes containing zeolite materials are produced by using fibrous sepiolite as a binder. The mechanical resistance of the resulting membranes decreases with the sepiolite clay content. However, at high zeolite concentrations, non-shape-selective pinholes are greatly reduced while the zeolite micropores are always accessible to diffusing molecules.
