2-15　Ethanol steam reforming reaction using novel carbon-CeO₂-ZrO₂ composite-supported cobalt catalysts

Abstract

Carbon-oxide-supported cobalt catalysts using ZrO₂ and CeO₂ were prepared by the sol-gel method using polyethylene glycol as a carbon source and zirconium alkoxide and their reactivity of steam reforming of ethanol was investigated. The hydrogen yield was improved by adding CeO₂ to 16Co63C21Zr. When the amount of CeO₂ added increased, the hydrogen yield increased and 16Co42C31.5Ce10.5Zr showed a hydrogen yield of 89% at a reaction temperature of 600°C.
