Investigation of heat exchanging reactor with heat-resistant anodized aluminum catalyst for hydrogen production process

Abstract

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%.
