- 論文の詳細を見る
Micro catalytic combustion of butane in microtube is investigated. Porous alumina fabricated on the inner surface of microtube through anodic oxidation of Al is employed for the support of Pt catalyst. Exhaust gas is sampled to measure its composition and the combustion efficiency. Combustion starts at 250℃, and a heat release rate up to 250MW/m^3 is achieved in a 0.6mm ID tube. A silicon-based catalytic combustor is designed and its prototype is fabricated using MEMS technologies. The Pt/alumina catalyst layer is successfully integrated onto a silicon microchannel, and a Pyrex lid is anodically bonded onto the Si substrate. It is found in a preliminary experiment that the MEMS combustor also works well, but gives somewhat smaller reaction rate due to the thinner catalytic layer.
