Abstract
Carbon dioxide (CO ) capturing by utilizing sustainable waste materials as an adsorbent is one of the emerging ideas in reducing air pollution nowadays. The abundance of these wastes generated on recurring bases from agricultural and forestry sectors (biomass) makes it to be sustainable. Moreso, biomass advantages for less pollution and low cost of production makes it a promising potential source for adsorbent. Empty fruit bunch (EFB) as one the most generated wastes from palm oil industry has been chosen for this study in order to assess its potential for CO 2 capture and de-capture. The raw EFB was first dried in roller oven under temperature condition of 100 2 o C for 24 hours, separated and stored in vacuumed desiccators. The dehydrated EFB was reduced with hydrogen and further treated with zeolite (sample 1) and stannum (sample 2) to improve or modify its affinity in CO 2 capturing. Both samples were introduced to a CO flow of 100mL/ min for 3 hours in quartz bed. Then de-capturing of carbon dioxide were performed using nitrogen gas at a flow rate of 100mL/min as desorption agent under 1.6bars pressure and 100˚C temperature for 3 hours and the performances were compared. The FTIR results indicated the presence of CO 2 2 in the range of 950-1300cm for sample 1 and 950-1300cm -1 for sample 2. It was also noticed that both adsorbents influenced the CO capturing and de-capturing process with sample 1 having the best combination to capture CO 2 and Sample 2 appeared to be suitable for de-capturing of CO 2 2 . These modified EFB sorbents can be a future potential source of adsorbents that would replace the existing/conventional adsorbents such as amine and activated carbon thereby reducing wastes generation annually as well as improving environmental air quality. -1
