Abstract： |
| In this paper, a dense ZIF-8 membrane was prepared inside the macroporous support by the restricted internal diffusion method, and its synthesis mechanism was explored. The results showed that when methanol was used as the solvent, zinc oxide gel was used, the internal diffusion time was 10 s, and the crystallization time was 10 h at 170 °C, dense membranes were successfully prepared in the pores of the tubular macroporous support. The results of single-component gas permeation experiments showed that the permeation rate of H2 is 5.53×10 -7 mol/(m2·s·Pa) at 25 ℃ and 0.1 MPa, and the ideal selectivities of H2/CO2, H2/N2 and H2/CH4 were 13.20, 12.96 and 12.89, respectively. |
