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.

微波在碳吸附剂表面刺激甲烷快速转化为氢
本文介绍了600℃微波辐照下等离子体催化甲烷直接分解快速制氢的研究结果。甲烷通过含铁碳吸附剂床层,该吸附剂是从具有大介电损耗切线的气煤中获得的。在MWI下,铁碳体系表面出现了强烈的击穿效应,并产生等离子体。等离子体中的甲烷转化为氢和碳。提出了微波刺激下水蒸气脱碳快速再生催化剂的方法。短周期实验表明,该催化体系具有较高的甲烷转化率和几乎完全的再生能力。

期刊介绍: Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
