高温工学試験研究炉(HTTR)と接続した熱化学的水素製造ISプロセスを想定して、生成水素,酸素の精製法の検討,評価を行った。分離膜法,圧力変動吸着(PSA)法,深冷分離法について現状の研究,開発を検討し、HTTR-ISシステムへの適用性を評価した。水素については、実績があり、成立性,健全性,信頼性などの面において現時点で最も優れていると考えられるPSA法が最も有効であった。併せて、分離膜法,PSA法による水素精製システムの概要を示した。

Purification methods of hydrogen and oxygen as products of thermochemical hydrogen production iodine sulphur (IS) process thermally connected with the High Temperature Engineering Test Reactor (HTTR) was investigated and evaluated. Present state of R&D of membrane separation method, pressure swing adsorption (PSA) method and cryogenic distillation method was researched and their applicability to the HTTR-IS system was evaluated. At present, PSA method was the most effective due to its feasibility, soundness and reliability with past performance. In addition, hydrogen purification systems by using PSA and membrane separation method were described in this paper.
