Accelerated CO Separation and Adsorption Kinetics on Carbon Using Resonant Vibrations: A Process Intensification Strategy

Payne Institute Faculty Fellow Amirhosein Riahi and Richard LaDouceur write about how carbonaceous adsorbents, such as biochar, have attracted considerable interest for CO2 sequestration because of their cost-effective production and environmental friendliness. However, their slow adsorption kinetics – attributable to limited surface area and diffusional limitations – have hindered widespread adoption.  In this study, we introduced a green processing strategy that leverages resonant vibrations to improve the rate of CO2 adsorption on hemp biochar.  January 28, 2026.
