บทคัดย่อ

Carbon dioxide (CO2) adsorption at various temperatures by the hexagonal ordered mesoporous synthesized from rice husk silica (R-MCM-41) was studied. The synthesized R-MCM-41 was confirmed by X-ray diffraction pattern and micrograph. FTIR analysis indicated the presence of well arranged siloxane bonding. R-MCM-41 showed type TV adsorption isotherm with hysteresis loop according to IUPAC classification. BET surface area, pore volume, and pore size distribution was 602.28 m2/g, 0.486 cm3/g, and 2.43 nm, respectively. The CO2 adsorption capacity of R-MCM-41 was investigated by using thermogravimetric analyzer (TGA) with temperatures varying from 30 to 150ฐC. The maximum adsorption capacity (23.32 mg-CO 2/g-asorbent) was obtained at 30ฐC. The adsorption capacity was decreased significantly when the adsorption temperature was increased. Furthermore, R-MCM-41 showed high stability in absorption-desorption reuse cycle. These results indicate that rice husk can be used as a source of silica for MCM-41 synthesis and further applied for CO2 adsorption in carbon capture technology.
