The activation using microwave-induced plasma with KOH (MiWP-KOH activation) can realize extremely fast synthesis of activated carbon (AC), which needed only several minutes. The present work focusses the effect of temperature-elevation rate on pore formation. For the discussion, AC was prepared using a conventional heat conduction method with various temperature-elevation programs, and the structural analysis results from these experiments were compared with those observed in AC prepared by the MiWP-KOH activation. As a feature in the pore structure of AC induced by the MiWP-KOH activation, micropore volume highly dominates over mesopore volume with (micropore/mesopore) ratio = 4.3–4.9. This property can be explained by the experiments with the controlled temperature-elevation rate, suggesting that rapid temperature-elevation rate is the key factor for such micropore-dominating structure. Additionally, it was suggested that the temperature of the feed material in the MiWP-KOH activation can become about 800 °C within 75 s. MiWP-KOH activation can generate significantly higher surface area than the conventional heating with the similar temperature changing program, suggesting the effect of microwave irradiation to enhance the pore formation. Based on these investigations, a characteristic pore formation model in the MiWP-KOH activation is considered.

使用 KOH 的微波诱导等离子体活化（MiWP-KOH 活化）可以实现极快的活性炭（AC）合成，仅需几分钟。目前的工作重点是升温速率对孔隙形成的影响。为了讨论，使用具有各种升温程序的传统热传导方法制备 AC，并将这些实验的结构分析结果与通过 MiWP-KOH 活化制备的 AC 中观察到的结果进行比较。作为 MiWP-KOH 活化诱导的 AC 孔结构的一个特征，微孔体积在中孔体积中占主导地位，（微孔/中孔）比 = 4.3-4.9。这种特性可以通过控制升温速率的实验来解释，表明快速升温速率是这种微孔主导结构的关键因素。此外，有人建议 MiWP-KOH 活化中的进料温度可在 75 秒内变为约 800 °C。MiWP-KOH 活化可以产生比具有相似温度变化程序的常规加热显着更高的表面积，表明微波辐射增强了孔隙形成的作用。基于这些研究，考虑了 MiWP-KOH 活化中的特征孔形成模型。MiWP-KOH 活化可以产生比具有相似温度变化程序的常规加热显着更高的表面积，表明微波辐射增强了孔隙形成的作用。基于这些研究，考虑了 MiWP-KOH 活化中的特征孔形成模型。MiWP-KOH 活化可以产生比具有相似温度变化程序的常规加热显着更高的表面积，表明微波辐射增强了孔隙形成的作用。基于这些研究，考虑了 MiWP-KOH 活化中的特征孔形成模型。
