Rapid Conversion of Methane to Hydrogen Stimulated by Microwave Irradiation on the Surface of a Carbon Adsorbent
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.
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.
