Аннотация:New catalysts have been developed for the production of synthesis gas via a resource-saving and environmentally friendly process—dry reforming of methane. The catalysts are fabricated from NdCaCo1– xNixOn precursors (x = 0, 0.2, 0.4, 0.6, 0.8, 1) synthesized by a ceramic method. According to X-ray powder diffraction, when reacting with an equimolar CH4/CO2 mixture at 800–900 С, the precursors are converted into a mixture of neodymium and calcium oxides and cobalt and nickel metals. The catalyst based on NdCaNiOn at 850С has ensured high conversions of methane (91%) and CO2 (86%) at СО and hydrogen yields of 88 and 78%, respectively. At 940 С, the yield of CO is close to the quantitative one (97%).
