Japan Atomic Energy Research Institute has been conducting R&D on HTGRs and hydrogen production method focusing on thermo-chemical IS process. Sulfuric acid decomposer is one of the key components of IS process, which decomposes H_2SO_4 into SO_3 and H_2O while evaporating sulfuric acid at high temperature conditions up to 500℃. Development of a sulfuric acid decomposer that features multi-hole-block type heat exchanger made of SiC ceramics is in progress and a pilot-scale mock-up model (block: 0.25m in diameter and 1.5m in height) has been test-fabricated. Also, two kinds of sulfuric acid circulation test loops were constructed to examine heat transfer characteristics of boiling sulfuric acid and the material compatibility for pipes, valves, pumps etc in the concerned process environments.
