Catalytic Materials Based on Hydrotalcite-Like Aluminum, Magnesium, Nickel, and Cobalt Hydroxides: Effect of the Nickel/Cobalt Ratio on the Results of Partial Oxidation and Dry Reforming of Methane to Synthesis Gas
Catalysts for the partial oxidation and dry reforming of methane based on hydroxo salts [AlMg2NixCoy(OH)(6.08)][(NO3) . nH(2)O], where x, y = 0, 0.005, 0.01, 0.02, 0.03, 0.035, and 0.04, with a hydrotalcite-like structure and a total Ni and/or Co content of no more than 2 wt % have been synthesized. It has been shown that Ni-Co catalysts with x = 0.03-0.035 and y = 0.005-0.01 provide a synthesis gas yield of 97-99% in both processes. At a low cobalt loading, the catalysts hardly form carbon nanotubes or other carbon depos-its.
