Effect of the Support Nature on Stability of Nickel and Nickel–Cobalt Catalysts for Partial Oxidation and Dry Reforming of Methane to Synthesis Gas

详细

It has been shown that the nature of the support (MFI zeolite, aluminum–magnesium hydrotalcite, stabilized ceria, neodymia) has a significant effect on the stability of Ni and Ni–Co catalysts for partial oxidation of methane to synthesis gas and a less significant effect on the stability of the catalysts for dry reforming of methane to synthesis gas. It has been found that aluminum–magnesium hydrotalcite is the most advantageous support for nickel catalysts, because it reliably provides a high synthesis gas yield in partial oxidation and dry reforming of methane, whereas the MFI zeolite is a stable and selective support for Ni–Co catalysts for dry reforming of methane.
