Investigation of CO2 adsorption on carbon material derived from Mesua ferrea L. seed cake.

In recent times, synthesis of valuable carbon materials via hydrothermal carbonization technique using biomass precursors for various applications has received revived interest in view of energy efficiency and sustainability. In present work, low-cost carbon material was synthesized using Mesua ferrea L. seed cake through hydrothermal carbonization method. The material was characterized using various techniques and its CO 2 capture performance was investigated through a dynamic column breakthrough measurements. The sorbent exhibited a fresh adsorption capacity of 2.63 mmol g −1 at 30 °C under a total pressure of 1 bar. Both textural properties and surface chemistry influence the CO 2 dynamic adsorption. The sorbent maintained an average working capacity of ∼ 2.47 mmol g −1 during eight cycles of adsorption-desorption. The experimental data can be adequately described by Yoon-Nelson kinetic model. The adsorption kinetic mechanism is further explained by applying intraparticle diffusion model to the experimental data. [ABSTRACT FROM AUTHOR]
