Adsorption with regeneration is a desirable process for controlling the emissions of organic vapors and separation and purification of gas streams because it allows for the recycle and reuse of the adsorbate hence contributing to sustainable industrial development. Adsorbents are typically regenerated by heating or applying vacuum. Steam and hot inert gas have been widely used for the regeneration of adsorbents. The regeneration of adsorbents has become an emerging concern because of its long duration and high energy requirements. More recently microwave and resistive heating have emerged as more effective regeneration techniques because of their faster rate and higher efficiency compared to regeneration with steam or inert gas. Microwave regeneration has also potential to minimize or eliminate irreversible adsorption and heel buildup. Tailoring the electric (i.e. resistivity) and dielectric (i.e. loss factor) properties of the adsorbent can allow for more effective and energy efficient regeneration of the adsorbent, and can indicate the degree of saturation or regeneration of the adsorbent.

吸附再生是控制有机蒸气排放和气流分离纯化的理想方法，因为它允许吸附物的再循环和再利用，因此有助于可持续的工业发展。吸附剂通常通过加热或施加真空来再生。蒸汽和热惰性气体已被广泛用于吸附剂的再生。吸附剂的再生由于其长的持续时间和高的能量需求而成为一个新兴的关注点。最近，微波和电阻加热已经成为更有效的再生技术，因为与蒸汽或惰性气体再生相比，它们的速度更快，效率更高。微波再生也有可能最大限度地减少或消除不可逆的吸附和脚跟建设。调整吸附剂的电（即电阻率）和介电（即损耗因子）性质可以允许吸附剂的更有效和能量有效的再生，并且可以指示吸附剂的饱和或再生程度。
