Abstract:
Dry reforming of methane (DRM) reaction (CH4(g) + CO2(g) → 2H2(g) + 2CO(g)) is an important process among clean energy sources because of syngas (mixture of H2 and CO) release as reaction products. Syngas product can be produced effectively at high temperatures (between 600 °C to 800 °C) in the presence of appropriate catalysts. Perovskite mixed-oxide materials are promising candidates as DRM catalysts because of their high activity and long term stability during the process. LaNiO3 and LaMnO3 were synthesized by ultrasonic spray pyrolysis (USP) method and their properties such as chemical composition, specific surface area and morphology were investigated by XRD, BET and FESEM analysis. H2/CO proportion of products for mentioned catalysts were measures after DRM process as catalysts activity parameter and obtained spent catalysts were also characterized by XRD, FESEM and TEM analysis in order to investigation of reducability, sinterability and resistance of coke formation.
