abstract

Small pore titanosilicate AM-3 has been prepared as a continuous layer on alpha-alumina and stainless-steel porous tubes by seeded hydrothermal synthesis The influence of the synthesis conditions has been studied and pure AM-3 membranes about 12 mu m thick have been obtained exhibiting a good intergrowth of crystals the samples have been characterised by X-ray diffraction scanning electron microscopy energy dispersive X ray spectrometry and X-ray mapping The membranes have also been evaluated by measuring the permeances of single gases at programmed temperature and their trends have been discussed The available evidence shows that the titanosilicate AM-3 membrane is a potential candidate for H-2 separation (C) 2010 Elsevier Inc All rights reserved
