Abstract

This research introduced structurally unique materials in carbon membrane field which are zeolite templated carbon (ZTC) and zeolite-carbon composite (ZCC) as a new filler for superior gas permeation and separation performance. By combining both the properties of zeolite and carbon, these two fillers are able to improve the overall separation performance of the carbon membrane. This research aims to study the physicochemical properties of ZCC and ZTC, study the effect of fillers loading on the P84 co-polyimide and investigate the pyrolysis temperature of composite carbon membrane. Zeolite Y, as a ZCC and ZTC template, was synthesized via hydrothermal method. ZCC was synthesized via impregnation method of sucrose as a carbon precursor and followed by carbonization at 800°C. The ZTC was obtained by template removal via acid treatment of ZCC. P84 co-polyimide polymer was used as a carbon membrane precursor. The composite membrane was fabricated into hollow fiber module via a dry-wet spin method. The gas test measurement covers single gas of H2, N2, CH2, O2, and CO2 on that order and binary gas mixture of CO2/CH4 and H2/CH4. The fillers study demonstrated that the physicochemical properties of ZCC and ZTC were suitable to improve the membrane separation performance. The optimum loading amount of ZTC and ZCC was at 1 wt% loading. At this loading the membrane thermal resistance improved by 7.37 and 19.32% for ZCC and ZTC, respectively. Moreover, the permeability demonstrating almost 1.7 - 2.18 times faster permeability and 1.2-1.39 better selectivity. The HFCMs pyrolyzed at 500°C showing the fastest permeability with improvement up to 10-33 times as compared to the polymeric membrane, while the best selective membrane were pyrolyzed at 700°C with improvement up to 7-16 order.
