AbstractCuO/Al2O3 sorbents based on three aluminas of different pore structure and surface area around 125 m2/g were prepared. Two of the aluminas exhibited bimodal pore size distribution, while the third had narrow unimodal distribution. The effect of copper loading on the physical characteristics of the aluminas (pore size distribution and surface area) was examined using mercury porosimetry and gas adsorption. The reactivity of the sorbents towards SO2 was investigated by carrying out thermogravimetric experiments using simulated flue gas.

Abstract This study presents two methods to improve the air filtration performance of konjac glucomannan (KGM)-based aerogel air filters through physical structure design by changing the pore-size distribution and the surface area, using an air purifier. Results indicated that KGM-based aerogels had a comparable filtration effect with the commercial air filter with a longer purification time. This purification time could be shortened by over 50%, by changing the pore-size distribution from large size to small size or increase the surface area with the fold structure. This should boost the development of polysaccharide-based aerogel used as the air filter.
