文摘Ferrierite zeolite membranes were prepared for the first time in the absence of organic structure-directing agents （SDA） on the surface of a porous a-alumina support. These membranes were characterized by means of X-ray diffraction （XRD）, scanning electron microscopy （SEM） and pervaporation tests.
