제목 Carbon dioxide physisorption behaviors of pine cone-based carbonaceous material at different temperatures
초록 Biomass-based activated carbons (ACs) are widely used as CO2 capturing materials. There has been a challenge to obtain highly well-developed ACs due to a phytolith component in the biomass that mainly comprises silica. The silica elimination process (SE) has rarely been studied for developing the porosity of ACs. Here, we prepared pre-carbonized pine cones (CPC) as a starting material to investigate optimizing the micropores of ACs according to the preparation sequence. One was prepared by chemical activation (CA) and the subsequent SE (CPC-CA-SE/ACs) and the other was carried out the SE before CA (CPC-SE-CA/ACs). From the results, we found that the preparation sequence had a strong effect on the textural properties of the resultant of biomass-based ACs and their CO2 capture performance.
