“…In addition, the rise in temperature in the conversion rate contributed to the increase in the conversion rate of CH 4 and CO 2 . This occurrence has been reported in previous studies [24]. As the temperature rose from 700 to 900 • C, the CH 4 conversion of Pd,Pd,Ni/Mg 0.85 La 3+ 0.15 O increased from 32.67% to 85% C, whereas the CO 2 conversion increased from 36.63% to 98.97%.…”

Pt,Pd,Ni/MgO, Pt,Pd,Ni/Mg0.97La3+0.03O, Pt,Pd,Ni/Mg0.93La3+0.07O, and Pt,Pd,Ni/Mg0.85La3+0.15O (1% of each of the Ni, Pd, and Pt) catalysts were prepared by a surfactant-assisted co-precipitation method. Samples were characterized by the XRD, XPS, XRF, FT-IR, H2-TPR, TEM, the Brunauer–Emmett–Teller (BET) method, and TGA and were tested for the dry reforming of methane (DRM). TEM and thermal gravimetric analysis (TGA) methods were used to analyze the carbon deposition on spent catalysts after 200 h at 900 °C. At a temperature of 900 °C and a 1:1 CH4:CO2 ratio, the tri-metallic Pt,Pd,Ni/Mg0.85La3+0.15O catalyst with a lanthanum promoter showed a higher conversion of CH4 (85.01%) and CO2 (98.97%) compared to the Ni,Pd,Pt/MgO catalysts in the whole temperature range. The selectivity of H2/CO decreased in the following order: Pt,Pd,Ni/Mg0.85La3+0.15O > Pt,Pd,Ni/Mg0.93La3+0.07O > Pt,Pd,Ni/Mg0.97La3+0.03O > Ni,Pd,Pt/MgO. The results indicated that among the catalysts, the Pt,Pd,Ni/Mg0.85La23+0.15O catalyst exhibited the highest activity, making it the most suitable for the dry reforming of methane reaction.

“…Generally, an enhancement in the CH 4 : CO 2 conversion of (1:1) was noted upon increasing the temperature from 700 • C to 900 • C, which may be attributed to the strong endothermic reaction of dry-reforming (Equation ( 1)). Earlier research reported an increase in the rate of conversion at higher temperatures [30]. It is demonstrated that an increase in the temperature (700-900 • C) led to an increase in the CH 4 conversion of Ni,Pd,Pt/Mg 0.85 Ce 4+ 0.15 O (33% to 78%) and an increase in the CO 2 conversion from 41% to 90%.…”

Catalysts Ni/Mg1−xCex4+O and Ni,Pd,Pt/Mg1−xCex4+O were developed using the co-precipitation–impregnation methods. Catalyst characterization took place using XRD, H2-TPR, XRF, XPS, Brunauer–Emmett–Teller (BET), TGA TEM, and FE-SEM. Testing the catalysts for the dry reforming of CH4 took place at temperatures of 700–900 °C. Findings from this study revealed a higher CH4 and CO2 conversion using the tri-metallic Ni,Pd,Pt/Mg1−xCex4+O catalyst in comparison with Ni monometallic systems in the whole temperature ranges. The catalyst Ni,Pd,Pt/Mg0.85Ce4+0.15O also reported an elevated activity level (CH4; 78%, and CO2; 90%) and an outstanding stability. Carbon deposition on spent catalysts was analyzed using TEM and Temperature programmed oxidation-mass spectroscopy (TPO-MS) following 200 h under an oxygen stream. The TEM and TPO-MS analysis results indicated a better anti-coking activity of the reduced catalyst along with a minimal concentration of platinum and palladium metals.

“…2020 metal catalysts and effective inhibiting of carbon deposition have become the main focus of research on methane reforming catalysts using carbon dioxide. Currently, Ni and Co based catalysts [13][14][15][16][17][18][19] are the most widely studied among the various types of studied catalysts. Typically, La 2 O 3 and CeO 2 are used as additives, and Al 2 O 3 , ZrO 2 , MgO and molecular sieves are used as carriers [20].…”

The world's oil reserves are shrinking every day due to continuous production and processing using the most modern technologies. Scientists around the world are looking for different types of raw materials and ways to use the vast resources of natural gas as a substitute for oil. In this regard, considerable attention is paid to natural and associated gas as an alternative source of raw materials for the petrochemical industry. In this paper, Ni, Co and Ni-Co catalysts carried to θ-Al2O3 prepared by the traditional method of air impregnation for moisture capacity are studied. The developed compositions of monometallic and bimetallic compositions of catalysts were studied by the XRD method. The efficiency of the dry methane reforming reaction was investigated in a stationary reactor under the optimal process conditions found experimentally: T = 700 and 900oC, GHSV = 6000 h-1 and CH4:CO2: Ar = 1: 1: 1.
