Abstract

A fluid fuel reforming ceramic catalyst comprising a core 2 of a complex oxide ceramic of transition metals, an intermediate layer 3 of an alumina-based silicate ceramic covering the core 2 and an outer layer 4 of a ceramic containing noble metals prepared by forming the core by firing the complex oxide ceramic of transition metals, coating the intermediate layer of the alumina-based silicate ceramic over the core, and coating the outer layer of the ceramic containing noble metals over the intermediate layer increases the octane number of fluid fuels, enhances their combustion efficiency, and decreases the noxious substances in exhaust gases.
