摘要：

In this paper, a series of cordierite-loaded Fe/Ce composite oxygen carriers were prepared by ball milling method and the performance of the composite oxygen carriers for methane chemical looping reforming was evaluated on a fixed-bed reactor. The effects of cordierite mass fraction, Fe/Ce molar ratio, coconut shells addition and ball milling parameters on the redox properties of the composite oxygen carriers were systematically investigated and corresponding characterizations (XRD, H2-TPR, BET, SEM, XPS) were performed. It was found that the composite oxygen carrier with 30% cordierite that loaded Fe/Ce at a molar ratio of 1∶9 and prepared under the ball milling parameters of ball material ratio of 10∶1, rotational speed of 500r/min, and time of 1h, had superior redox properties. The addition of 15% coconut shell carbon increased the actual oxygen output of the composite oxygen carrier by 38.7%, and also demonstrated a good reaction stability and oxygen release capability in the reduction-oxidation cycle reactions. © 2024 Chemical Industry Press Co., Ltd..
