Modified ceria-zirconia oxides were prepared in supercritical fluids in flow-type installation. Ni was added by wetness impregnation. All materials were studied by a complex of physicochemical techniques (XRD, TEM, H2-TPR). Catalysts have been investigated in a modern process – chemical looping methane dry reforming (CLMDR). Conversions of CH4 and CO2, H2/CO ratio, H2 and CO productivities were calculated. The features of CLMDR process were compared with results obtained in MDR steady-state conditions.

Модифицированные оксиды церия-циркония были приготовлены в сверхкритической среде в проточной установке. Никель наносили методом пропитки по влагоемкости. Все материалы были исследованы комплексом физико-химических методов (РФА, ПЭМ, H2-ТПВ). Катализаторы были испытаны в современном процессе – углекислотной конверсии метана в режиме химического циклирования. Были рассчитаны конверсии CH4 и CO2, соотношение H2/CO и продуктивности по H2 и CO. Полученные данные сравнивали с результатами углекислотной конверсии метана в стационарных условиях.
