Study on the Reaction of NCFO-BZCYYb Catalyst of Methane Steam Reforming

Abstract:

Ni_0.5Cu_0.5Fe₂O₄ and BaZr_0.1Ce_0.7Y_0.1Yb_0.1O_3-d were prepared by an aqueous sol–gel process. The Ni_0.5Cu_0.5Fe₂O₄were modified by various content of BaZr_0.1Ce_0.7Y_0.1Yb_0.1O₃_-d. Their microstructure and phase were observed by SEM and XRD. We studied the effect of BaZr_0.1Ce_0.7Y_0.1Yb_0.1O_3-d on the methane reforming property of catalyst powder at 650°C, 20ml/min CH₄ and x wt. % water vapor (x=3, 10). The composition of exhaust gas was monitored by on-line mass spectrometer. It shown that with the increase of BaZr_0.1Ce_0.7Y_0.1Yb_0.1O_3-d, the conversion of CH₄ decreased. Moreover, the selectivity of CO decreased when water vapor added. Investigated the microstructure and Raman of the power that has catalyzed for 4 hours, It can be found that there were only a few deposited carbon almost cannot detect by Raman.
