Abstract：

Hybrid carbon membranes are first prepared using BPDA-ODA type polyimide and zeolites as precursors and additives, respectively. The thermal stability of the precursor was measured by thermogravimetric analysis. The microstructure, morphology and gas separation performance of resultant carbon membranes were characterized by X-ray diffraction, scanning electronic microscopy and gas permeation technique, respectively. The effects of zeolite types (ZSM-5 and 5A), zeolite dosage, carbonization temperature, and permeation-temperature and permeation-pressure were investigated on the gas separation performance of hybrid carbon membranes. The results have shown that the permeation mechanism for the four gases, H2, CO2, O2 and N2, is molecular sieving through the hybrid carbon membranes. When the hybrid carbon membranes are prepared at the carbonization temperature of 650 oC, both of their permeability and selectivity slightly reduce. In comparison, 5A is more favorable than ZSM-5 to be used as additives with the aspect to increase separation performance of resultant carbon membranes. With increasing the permeation pressure, both the permeability and selectivity increase. As the carbonization temperature goes up from 650 oC to 750 oC, the permeability of hybrid carbon membranes reduces.
