摘要

The perovskite metal-oxides LaNi_xFe_(1-x)O3 (0≤x≤l) were synthesized by a sol-gel method and investigated for the DR, POM, and CRM into synthesis gas. The catalysts were characterized by using XRD, BET, CA, SEM, EDS, HR-TEM, EDX and TPR in order to investigate the influence of the preparation parameters and evaluation condition. LaNi_(0.4)Fe_(0.6)O3 showed great stability, and fewer carbon deposits were detected on the spent catalyst after 1800 min evaluation on TOS. The effect of GHSV on the catalytic performance was investigated. The results obtained showed the H2/CO molar-ratio was around 0.9,1.7, and 1.1 over different catalysts for DR, POM and CRM, respectively.
