摘要：

Ni-Co/gamma-Al2O3 bimetallic catalysts were synthesized by capillary impregnation (CI) and solution combustion methods (SC). Catalysts tested in dry methane reforming (DRM), characterized by XRD, H-2-TPR, SEM, small-angle X-ray scattering. Preparation method plays an important role in regulating the textural and morphological properties of catalysts and provides a difference in indices of their activity. Synthesis of Ni-Co/gamma-Al2O3 by SC in comparison with CI method leads to formation of solid solution of NiCo2O4 with a CSR size of 21 nm, increases the proportion of metal ions (Ni, Co) reduced at temperatures of 400-700 degrees C, uniform distribution of nanosized particles of active phase on carrier surface. At comparatively low reaction temperature (600 degrees C) on sample synthesized by SC, degree of methane conversion is higher compared to sample prepared by CI, X-CH4-69%, X-CH4-65%, respectively. SC provides an efficient way to develop an active catalyst for DRM at low temperatures (600-750 degrees C).
