Summary: In this study, the chemical looping reforming (CLR) of toluene was investigated using 6Ni, 4Ni2Cu, and 4Ni2Fe as oxygen carriers (OCs) at different temperatures and steam/carbon molar ratios (S/C). Experimental results showed that the metal OCs had a dual-function of oxidation-catalysis for CLR of toluene. Among the three OCs, 4Ni2Fe exhibited the best carbon deposition resistance and demonstrated stable performance during 10 cyclic experiments, making it the most ideal OC for the CLR of toluene.
