Performance of Iron-Based Perovskite-type Oxides for Chemical Looping Dry Reforming of Methane

Abstract

Partial oxidation of methane has emerged as a promising approach for the effective utilization of methane. When combined with the thermochemical CO 2 reduction through the "chemical looping" concept, it can realize the coproduction of syngas and high-purity carbon monoxide. In this study, we proposed a chemical looping dry reforming of methane (CL-DRM) process by using iron-based perovskite-type oxides as oxygen carriers (OCs). This process has the potential to efficiently utilize low-grade solar heat and convert it into high-grade chemical energy. To identify efficient perovskite-type OCs, we synthesized and characterized
