日本原子力研究開発機構では、高温ガス炉の核熱を用いて水から水素を製造する熱化学法ISプロセスの研究開発を進めている。熱化学法ISプロセスにおける硫酸分解工程の高効率化及び簡素化が期待できる直接接触式硫酸濃縮器の設計に必要となる物質移動係数の測定方法を検討し、濡れ壁塔を用いた試験装置を設計・製作した。本報では製作した試験装置による予備試験結果について報告する。

The Japan Atomic Energy Agency has been conducting R&D on thermo-chemical IS process, which is one of most attractive water-splitting hydrogen production methods using nuclear heat of a high temperature gas-cooled reactor. The present study concerns with development of IS process equipment utilizing direct contact heat exchanger (DCHX). The concept is very attractive in terms of the development of compact and efficient sulfuric acid concentrator. Experimental methods were discussed to acquire the gas-phase mass transfer coefficient required for the optimal design of DCHX. Experimental setup composed of wetted-wall column was manufactured to measure the mass transfer coefficients. In this paper, we report preliminary experimental results of water.
