摘要：

Zeolite membrane (MCM-22/-Al2O3) was prepared on -Al2O3 disk by synthesis method (rubbing) and investigated through water separation and oily water recovery. The materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and mercury porosimetry. Thereafter, the separation of oil-water emulsion was evaluated. The crystallization behavior of the particles of the zeolite membrane is observed through the XRD. The images obtained by SEM of the zeolite membrane (MCM-22/-Al2O3) showed that the method used for the synthesis of the zeolite membrane was effective since it showed the formation of a homogeneous surface with no cracks or defects on the surface of the porous support of -Al2O3. Oil rejection was monitored. Fouling occurred as a layer on the membrane surface. The test showed that the MCM-22 zeolite membrane has potential for oil-water separation.
