| 英文摘要 | silicalite-1/ceramic composite membrane was prepared on the outer surface of the alpha-al2o3 tubular support by in-situ hydrothermal synthesis. the membrane was characterized by x-ray diffraction (xrd) and scanning electron microscope (sem). the pure gas permeances of h-2, n-2, ar, ch4, c2h4, c2h6, c3h8, n-c4h10 and i-c4h10 were measured as a function of the pressure difference at 298 and 473 k. the permeances of h-2, n-2 and ar showed little dependence on the pressure differences; the permselectivities of h-2/i-c4h10 were 249 and 36.2 at 298 and 473 k respectively, which is a characteristic of molecular transport in silicalite-l channels. the permeances of light alkanes decreased in the following order: ch4 > c2h6 > c3h8 > n-c4h10 > i-c4h10. the permselectivity of n-c4h10/i-c4h10 was above 15 at 298 k. as the temperature increased, the permeances of all gases increased except those of n-2 and ar, and a significant increment was found for alkanes. the permselectivity of n-c4h10/i-c4h10 decreased to about 9 at 473 k. the gas permeation results showed that the silicalite-1/ceramic composite membrane was defect-free. |
