Dry reforming of methane (DRM) is a promising method to utilize two greenhouse gases, such as CH4 and CO2, to produce synthesis gas. In the current work, both monometallic Ni and bimetallic Ni–Fe catalysts with different Fe/Ni molar ratios, synthesized by solution combustion synthesis (SCS) in DRM, were investigated using a feed ratio of CH4/CO2/Ar of 1:1:1 at 600–900 °C. The catalysts were characterized by several physicochemical techniques such as X-ray diffraction (XRD), scanning electron microscopy energy-dispersive X-ray (SEM-EDX) spectroscopy, transmission electron microscopy (TEM), CHNS, N2 physisorption, H2-TPR, O2-TPO, NH3-TPD, and thermogravimetric analysis (TGA). One of the highest hydrogen yields of 81% was obtained at 93% conversion of CH4 and 94% conversion of CO2 for the bimetallic 15Ni–5Fe–30Al catalyst, which contained, according to XRD, NiAl2O4 spinel and metallic Ni phases. The spinel phase was decomposed during the reaction, while the Ni3Fe alloy was formed. Catalysts with a higher Fe/Ni ratio exhibited lower conversion and contained an inactive FeAl2O4 spinel. Rather stable yields of CO and H2 were obtained in an experiment with 20 h time-on-stream.

A Pt‐Ru/2 % Ce/(θ+α)‐Al2O3 nanosized catalyst was developed for selective catalytic oxidation of CH4 to synthesis gas. The process was carried out entirely with the formation of synthesis gas at high selectivity by H2 and CO with H2:CO = 2.0 ratio only at Pt:Ru = 2:1 or 1:1 atomic ratio and short contact time on Pt‐, Ru‐, and Pt‐Ru low‐percentage catalysts. Samples, which were reduced by H2 at high temperature, presented a mixture of Pt‐, Ru‐, and Pt‐Ru nanosized particles, its alloy in the mixed catalysts. The correlation between experimental results and data of physicochemical research was established. The activity together with physicochemical properties and quantum chemical calculations for the developed low‐percentage Pt‐Ru catalysts was investigated.

The aim of this research was to develop the technology of new composite material synthesis for the processing of natural gas methane into olefins. The effects of technological parameters (temperature, volumetric rate, reaction mixture composition) on methane's oxidative conversion into important petrochemical products has been studied. The paper presents data on methods developed for synthesis and physicochemical characteristics of catalysts. The technological parameters of the process conducted by means of integrated automated laboratory setup were optimized. It has been established that 10% K-30% Mn-10% Nb/50% glycine catalyst prepared by the solution combustion synthesis (SHS) method in solution was active for olefin formation at oxidative transformation of mixture 41.8% CH 4 +16.2% O 2 +42% Ar at a volumetric velocity of 3500 h -1 . It was determined that at T=800°С, yields of C 2 H 6 and C 2 H 4 were 3.3 and 14.3%, respectively.
