Abstract：
The low cost and high efficiency of microwave-assisted regeneration render it a viable alternative to conventional regeneration methods. To enhance the regeneration performance, we developed a coupled electromagnetic, heat, and mass transfer model to investigate the heat and mass transfer mechanisms of activated carbon during microwave-assisted regeneration. Simulation results demonstrated that the toluene desorption process is governed by temperature distribution. Changing the input power and flow rate can promote the intensity of hot spots and adjust their distribution, respectively, thereby accelerating toluene desorption, inhibiting readsorption, and promoting regeneration efficiency. Ultimately, controlling the input power and flow rate can flexibly adjust toluene emissions to satisfy the processing demands of desorbed toluene. Taken together, this study provides a comprehensive understanding of the heat and mass transfer mechanisms of microwave-assisted regeneration and insights into adsorbent regeneration.

微波辅助再生的低成本和高效率使其成为常规再生方法的可行替代方案。为了提高再生性能，我们开发了一种耦合电磁，热,和传质模型来研究活性炭在微波辅助再生过程中的传热和传质机理。模拟结果表明，甲苯的解吸过程受温度分布的影响。改变输入功率和流量可以促进热点的强度并调整其分布，分别,从而加速甲苯的解吸，抑制再吸附，提高再生效率。最终,通过控制输入功率和流量,可以灵活调节甲苯的排放量,满足解吸甲苯的处理需求。一起来看,这项研究提供了对微波辅助再生的传热和传质机理的全面了解和对吸附剂再生的见解。
