Abstract
Using hydrotalcite-like compounds as the precursor,a series of supported Ru/Mg(Al)O catalysts with Ru mass fractions of 1%,2% and 4% were prepared by coprecipitation method.The catalysts were characterized by using the techniques of XRD,H2-TPR and CO chemisorptions.The influence of Ru loadings on the activity and stability of the catalysts for CH4-CO2 reforming reaction was investigated.The results of XRD and CO chemisorption indicated that the number of Ru surface active sites on Ru metal particles increased with the increase of Ru loadings,however,higher Ru loading led to lower metal dispersion and larger metal particles.The results of activity tests showed that the highest activity was achieved on 2Ru/Mg(Al)O catalyst,and 1Ru/Mg(Al)O catalyst exhibited higher stability at 750 ℃ for reaction time 30 h,which might be related to the strong interaction between the highly dispersed Ru metal particles and Mg(Al)O support.
