Abstract:
In this study, a novel bio-based adsorbent was developed for biohydrogen purification by an adsorption process. Palm shell activated carbons were immersed in the chitosan solutions at the concentrations between 0.1-2 g/L.The results showed that the impregnation of chitosan onto activated carbons at every concentration under the investigation changed the BET surface areas, pore size distribution, CO2 adsorption capacity and the CO2/H2 selectivity. The chitosan impregnated activated carbon that was the most suitable for carbon dioxide/hydrogen separation was the one impregnated in the 0.1 g/L chitosan solution yielding 0.12 g chitosan per 100 gram activated carbon. The modified activated carbon was found to have 11% higher CO2 adsorption capacity than the native activated carbon even though its BET surface area was reduced by 3% due to the impregnation process. From a lab-scale pressure swing adsorption process using the modified activated carbon as the adsorbent (under an adsorption pressure of 4 bar and the feed flow rate of 2 L/min 50-30-20 mixture of CO2, H2 and N2 for a period of 2 min per cycle), the CO2 concentration in the effluent was not detected for at least 5 cycles.
