Abstract
This study explores the CO2 capture process through adsorption on fine porous materials in a sound-assisted fluidized bed. Activated carbons made from coal, coconut and wood were chosen and tested in a custom-designed experimental setup. Minimum fluidization velocities were recorded at different sound intensities (20–135 dB) and frequencies (50–200 Hz). Statistical analysis using ANOVA showed cubic relationships between fluidization velocities and sound parameters, with R² values over 0.91 for all materials. CO2 adsorption tests indicated improved performance at specific sound conditions, with coconut-based carbon showing the best adsorption efficiency. This work emphasizes the importance of sound in improving fluidized bed operations for effective CO2 capture.
