Advancing Co2 Separation and Capture in Post-Combustion Scenarios Using Resonant Vibration Techniques

Payne Institute Faculty Fellow Amirhosein Riahi, Julie Muretta, and Richard LaDouceur write about how carbon dioxide (CO2) requires specialized capture methods for effective mitigation. Biochar has garnered significant interest as a versatile, porous solid adsorbent due to its cost-effective production, thermal, chemical, and mechanical stability, and minimal environmental impact. However, its small surface area and diffusional issues result in slow CO2 adsorption kinetics and limited capacity, hindering widespread adoption.  February 14, 2025.
