水素製造プロセスに用いる耐熱アルマイト触媒熱交換型反応器の検討

抄録

Simulation study was conducted for a catalytic reaction using a high temperature heat exchanging type reactor with the heat-resistant anodized aluminum catalyst. SO₃ decomposition reaction in the Iodine-Sulfur thermochemical hydrogen production process was adopted as a model reaction. Effect of catalyst shape on the heat exchanging performance was estimated. The shape of a catalyst was good in heat exchanging performance by order of a serrated fin type, a fin type, a plate type and a packed bed type reactor. In comparison with the packed bed type reactor, the reactor volume of serrated fin type reactor to be necessary for the decomposition reaction decreased to 35%. In addition, the exergy losses caused by a heat exchanging operation decreased to 64.2%.
