| description | The worldwide increase in demand for environmentally friendly energy has led to the intensification of work on the synthesis of H<sub>2</sub>-containing fuel. The dry reforming of methane has become one of the most important avenues of research since the consumption of two greenhouse gases reduces the rate of global warming. A study of NiAl composite materials as catalysts for methane reforming has been carried out. Self-propagating high-temperature synthesis (SHS) has been used to produce NiAl catalysts. Comparative studies were carried out regarding the dry reforming and partial oxidation of methane, as well as catalysts prepared using the impregnation (IM) and SHS methods. A catalyst with 29% Ni and 51% Al after SHS contains the phases of NiAl and NiAl<sub>2</sub>O<sub>4</sub>, which are active phases in the dry reforming of methane. The optimal crystal lattice parameter (for the maximum possible conversion of CO<sub>2</sub> and CH<sub>4</sub>) is 3.48–3.485 Å for Al<sub>2</sub>O<sub>3</sub>, which plays the role of a catalyst carrier, and 1.42 Å, for NiAl<sub>2</sub>O<sub>4</sub>, which plays the role of a catalyst. The aim of the work is to develop a new and efficient catalyst for the dry reforming of methane into a synthesis gas, which will further promote the organization of a new era of environmentally friendly energy-saving production methods. |
