Abstract

The paper presents the results on the rapid production of H₂ from CH₄ by its direct decomposition in a plasma-catalytic mode stimulated by microwave irradiation (MWI) at 600°C. Methane was passed through a bed of iron-containing carbon adsorbent obtained from gas coal characterized by a large dielectric loss tangent. Under MWI, intense breakdown effects with plasma generation appear on the surface of the iron–carbon system. Methane in the plasma converts to hydrogen and carbon. A method has been developed for the rapid regeneration of the catalyst by water vapor with the removal of carbon under microwave stimulation. Short-cycle experiments have shown that the catalytic system provides high conversions of methane and its almost complete regeneration.

微波辐照在碳吸附剂表面刺激甲烷快速转化为氢气

摘要

该论文介绍了通过 CH ₄在 600°C 微波辐射 (MWI) 激发的等离子体催化模式下直接分解，快速生产 H ₂的结果。甲烷通过含铁碳吸附剂床，该吸附剂从气煤获得，其特征在于大介电损耗角正切。在 MWI 下，铁碳系统的表面出现等离子体产生的强烈击穿效应。等离子体中的甲烷转化为氢和碳。已经开发了一种在微波刺激下通过去除碳的水蒸气快速再生催化剂的方法。短周期实验表明，催化系统提供了甲烷的高转化率和几乎完全的再生。
