Abstract:
To develop an effective catalyst for the resource-saving conversion of coal-industry methane into hydrogen-containing gas, the materials Ce0.2Ni0.8O1.2/Al2O3 were synthesized, their physicochemical and functional properties were studied depending on the nature of the precursors of active components (nickel(II) nitrate hexahydrate, nickel(II) ammonium oxide) and promoters (cerium(III) nitrate hexahydrate, ammonium cerium(IV) nitrate). It is shown that the nature of the precursor affects the textural and structural characteristics of the samples, their catalytic activity in the steam-carbon dioxide reforming of methane and resistance to the formation of carbon deposits. The optimal composition of precursors (nickel (II) nitrate hexahydrate, cerium(III) nitrate hexahydrate) has been established, the use of which in the synthesis of the Ce0.2Ni0.8O1.2/Al2O3 catalyst ensures a decrease in the average particle size of the Ni active component (25 → 6.5 nm) and the degree of catalyst carbonisation (2.9 → 0.5%), high hydrogen yield (95%) at 800 °C in the steam-carbon dioxide reforming of methane.
