摘要: Abstract Autothermal reforming of methane (ATRM), combination partial oxidation and steam was performed over MgO supported Ni catalysts. The preparation via surfactant-assisted precipitation method led to obtain a nanocrystalline carrier for nickel results demonstrated that conversion is significantly increased with increasing the content (5, 7, 10 15%Ni) 15%Ni/MgO higher than other catalysts lower loading in all operation temperatures. In addition, system temperatures decrease H2/CO due fact water-gas shift reaction thermodynamically unfavorable at elevated This catalyst also exhibited stable catalytic performance during 50 h time on stream. Furthermore, influences varying GHSV feed ratio activity were investigated.
