Abstract
CoNdOx (Co/Nd = I) is a highly promising catalyst for the carbon-free CO 2 reforming of methane. Influence of the Co/Nd ratio on the catalyst performance in the CO 2 reforming and also on the crystalline phases and reduction by temperature programmed reduction (TPR) of the CoNdO x catalyst has also been investigated. The CoNdO x (CoNd = 1.0) catalyst consisted of mainly NdCoO 3 perovskite-type mixed metal oxide and it showed not only a high resistance to carbon formation at different process conditions (viz. temperature = 750-900 °C and gas hourly space velocity (GHSV) = 10000 50000 cm 3 g -1 h -1 ) but also high activity and selectivity in the CO 2 reforming process. The high resistance to carbon formation for this catalyst is attributed mostly to strong metal (Co°)-support (Nd 2 O 3 ) interactions.
