| 英文摘要 | a high quality pure hydroxy-sodalite zeolite membrane was successfully synthesized on an alpha-al2o3 support by a novel microwave-assisted hydrothermal synthesis (mars) method. influence of synthesis conditions, such as synthesis time, synthesis procedure, etc., on the formation of hydroxy-sodalite zeolite membrane by mahs method was studied by x-ray diffraction (xrd), scanning electron microscopy (sem) and gas permeation measurements. the synthesis of hydroxy-sodalite zeolite membrane by mahs method only needed 45 min and synthesis was more than 8 times faster than by the conventional hydrothermal synthesis (chs) method. a pure hydroxy-sodalite zeolite membrane was easily synthesized by mahs method, while a zeolite membrane, which consisted of nax zeolite, naa zeolite and hydroxy-sodalite zeolite, was usually synthesized by chs method. the effect of preparation procedures had a dramatic impact on the formation of hydroxy-sodalite zeolite membrane and a single-stage synthesis procedure produced a pure hydroxy-sodalite zeolite membrane. the pure hydroxy-sodalite zeolite membrane synthesized by mars method was found to be well inter-grown and the thickness of the membrane was 6-7 mum. gas permeation results showed that the hydrogen/n-butane permselectivity of the hydroxy-sodalite zeolite membrane was larger than 1000.
