| Abstract Scope |
Scalable production remains a major barrier to the practical use of biomass-derived carbons for CO2 capture. In this work, corn-fiber waste was converted into reduced-graphene-oxide-integrated bio-carbon by continuous one-pot pyrolysis at 650 °C under N2, using only graphene oxide and no chemical activation or post-treatment. The pilot-scale product retained the open, defect-rich structure developed at laboratory scale and reached a BET surface area of 275.2 m2 g-1, compared with 290.9 m2 g-1 for the laboratory material. At 298 K and 1 bar, the laboratory- and pilot-scale sorbents captured 2.54 and 2.32 mmol g⁻1 CO2, respectively, meaning that the pilot material retained 91% of the laboratory uptake. Repeated adsorption-desorption tests up to the 10th cycle showed stable performance, while CO2-TPD peaks at 111–120 °C indicated mainly weak-to-moderate binding. This approach provides a practical foundation for the future large-scale deployment of regenerable corn-fiber-derived sorbents for near-ambient CO2 capture. |
