AbstractReverse water-gas shift (RWGS) reaction over La 2NiO 4 catalyst was investigated during CH 4/CO 2 reforming by continuous wave cavity enhanced absorption spectroscopy, a sensitive absorption technique. The results indicated that the RWGS reaction promoted the conversion of CO 2 and decreased the partial pressure of hydrogen. By proper adjustment of the pressure of the reaction system, it is possible to suppress the occurrence of RWGS reaction and increase the selectivity of CH 4/CO 2 reforming. The intermediates of CH 4/CO 2 reforming such as CHO, OH and CH 3 were observed by means of the liquid-N 2 quenching technique, and a reaction step: CH x + [O] = CH x O was primarily confirmed. In addition, XPS and XRD results verified that nickel over catalyst after CH 4/CO 2 reforming existed in elemental state. The HRTEM images of used catalyst indicated that the deactivation of catalyst was originated mainly from the formation of nanotubes and graphite carbon on active sites of nickel. © 2006 Springer Science+Business Media, Inc.
