Abstract—The effect of modifying additives of copper, neodymium and molybdenum on acidity and dispersity of nickel catalyst was studied by temperature-programmed desorption of ammonia and scanning electron microscopy methods. Their activity in the reaction of partial oxidation of methane (POM) and dry reforming of methane (DRM) were measured. The NiCuNdMo/Al2O3HZSM-5 was found to be the best catalyst. The introduction of molybdenum into the composition of NiCuNd/Al2O3HZSM-5 catalyst was determined to increase general acidity of the catalyst from 26.71∙10-4 to 29.46∙10-4 mol / gКt, and also it increases the dispersion of the active phases of the catalysts surface. This data of change positively affects the activity of the catalyst in POM reaction, concentration of hydrogen in the reaction product compared with NiCuNd/ Al2O3HZSM-5 increases from 60 to 70 vol. %. The investigation of the catalytic activity of NiCuNdМо/Al2O3HZSM-5 catalyst in the reaction of DRM has shown that equilibrium yield of H2 and CO is observed in the temperature range of 650-900 °C. The main product in the process of oxidative conversion of methane by oxygen is hydrogen, whereas in the process of oxidative conversion of methane by carbon dioxide synthesis gas is formed.

Index Terms—Nickel-containing catalyst, methane, oxygen, carbon dioxide, hydrogen.
