9-1-1 Development of Efficient Cold-Start Process for Oxidative Reforming of n-Butane Based on Redox Property of Oxide Supported Catalyst.

Abstract

We demonstrated the cold-start process for oxidative reforming (OR) of n-butane. In this process, without heating the catalyst by external energy OR is triggered rapidly and repeatedly over reduced CeO₂ supported Rh catalysts from ambient temperature. Redox property of oxide support, i.e. spontaneous oxidation of the reduced catalyst support, CeO_2-x to CeO₂, and in-situ reduction of the catalyst support during OR, CeO₂ to CeO_2-x, are found to be key factors for construction of this process.
