摘要

In this study, the membrane and the adsorption technologies approach are developed and used as a separation technique to separate carbon dioxide (CO2) and hydrogen (H-2) gas mixture from biohydrogen dark fermentation. For a real application, the effect of CO2 impurity in the H-2 fuel (i.e., the gas output from separation techniques) toward the PEM fuel cell performance was studied. Hence, a novel synthesized membrane made of glassy polymers, polyetherimide (PEI) coated bio-cellulose nanofibers and a coconut shell activated carbon (CAC) as adsorbents carriers were used. For the membrane separation technique, the bio-cellulose nanofiber is coated with PEI at varying concentration from 3 to 15 wt.%. The effect of PEI concentrations on the gas permeability and selectivity were observed. Meanwhile, for the adsorption separation technique, the performance of activated carbon was tested by using 0.6 L single column adsorber unit. The characterization of both developed membrane and adsorbent were analyzed including their morphologies and the physical properties. From the results, at 3 wt.% PEI coating, the CO2 permeability was 16.72 Barrer and corresponding selectivity of CO2/H-2 was 0.15. Moreover, the adsorbents carriers showed a better adsorption capacity for CO2 removal at which 77.17 mg of CO2/g of adsorbent in a lower flow rate of feed gas at 0.5 L/min. In the case of PEM fuel cell, the performance would decrease with the increase of CO2 impurity in H-2. Therefore, the results presented on this paper are the initial findings generated for the biohydrogen separation technology for the future portable power of PEM fuel cell application.
