通过球磨法制备一系列堇青石负载Fe/Ce的复合载氧体,并在固定床装置上评价复合载氧体的甲烷化学链重整的反应性能.系统考察了堇青石质量分数、Fe/Ce摩尔比、椰壳添加量以及球磨参数对复合载氧体的氧化还原性能的影响,并进行了一系列表征(XRD、H2-TPR、BET、SEM、XPS).研究发现,在球料比10∶1、转速500r/min、时间1h的球磨参数下制备质量分数30%堇青石负载Fe/Ce摩尔比为1∶9的复合载氧体具有较优的氧化还原性能.质量分数15%椰壳炭的添加使复合载氧体的实际出氧量提升了38.7%,并且在还原氧化循环反应中表现出良好的稳定性和氧释放能力.
Methane chemical looping reforming over cordierite-loaded Fe/Ce oxygen carriers prepared by ball milling
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.
