Abstract

The formation of a ferrierite (FER) membrane by a vapor-phase transport method is discussed. The formation process was studied using X-ray diffraction, scanning electron microscopy (SEM), field emission-SEM and energy dispersive X-ray analysis. The same location on the top surface was repeatedly observed at different crystallization times using SEM. It was found that an aluminosilicate species formed from a dry gel layer was mobile over the surface of support during crystallization. This intermediate aluminosilicate species penetrated into the pores of the alumina support to fill them, generating a compact FER-alumina composite layer.
