摘要: Abstract Nanocrystalline MgO with a relatively high surface area and mesoporous structure was synthesized by surfactant assisted precipitation method for use as the support of nickel catalysts steam reforming methane. The samples were characterized X-ray diffraction, N 2 adsorption, temperature-programmed reduction, oxidation, scanning electron microscopy, transmission microscopy. showed catalytic activity good stability in Increasing loading up to 10 wt% gave increased activity. Catalysts higher loadings more deposited carbon after reaction. excellent anti-coking performance attributed formation nickel-magnesia solid solution, basicity surface, nickel-support interaction.
