Abstract

This paper describes the synthesis and characterization of La_0.8Sr_0.2NiO₃ nano-perovskite type catalyst for steam-CO₂ reforming (SCR) and CO₂ reforming (DR) of methane. Effect of gelation agents such as PVA, EDTA and PAA on nano-perovskite structures was investigated. XRD, H₂-TPR and FT-IR analysis were used to characterize the prepared catalysts. The catalytic reaction was performed in a fixed bed reactor system at 1 atm and 800 °C. The feed ratio of CH₄:H₂O:CO₂ as reactants was adjusted according to the SCR and DR reactions. As a result, CH₄and CO₂ conversions of PVA agent catalyst were higher than that of PAA and EDTA agent catalyst for DR reaction because the PVA agent catalyst had a well-established perovskite, a high absorption, a high reducibility However, the PAA agent catalyst had a higher reactivity due to its high interaction of catalysts for SCR of methane due to its strong interaction of catalysts.
