| Abstract(J) | SOECを用いたメタン製造システムに，原料ガスに残留する窒素と酸素が混入した場合のシステムエネルギー効率について検討した．混入がない場合のエネルギー効率は85.1%であるのに対し，窒素60%，酸素6%混入の場合は47.9%となった．システム上流へのPSA導入によりエネルギー効率は84.0%となった． Translation |
| Abstract(E) | Co-electrolysis, which is the electrolysis of carbon dioxide and water vapor into hydrogen and carbon monoxide by supplying electric power to solid oxide cells, has attracted much attention because of its high energy conversion efficiency. However, since some carbon dioxide sources contain nitrogen and unburned oxygen, a system analysis of the effect of the concentration of these gas mixtures on energy efficiency was conducted. As a result, it was shown that the efficiency was greatly reduced when both nitrogen and oxygen were supplied at the same time, compared to the case where only nitrogen or oxygen was mixed. |
