Catalytic conversion of greenhouse gases (CO2 and CH4) to syngas over Ni-based catalyst: Effects of Ce-La promoters

Hydrogen‐rich syngas production from bi‐reforming of greenhouse gases over zirconia modified Ni/ MgO catalyst

“…Synthesis gas (syngas), a mixture of hydrogen and carbon monoxide is used as feedstock in the production of a variety of hydrocarbons, fuels, and oxygenates through reforming processes. 4,5 In particular, steam-CO 2 reforming of methane, also termed as bi-reforming of methane (BRM) (Equation [1]) is a feasible method for producing syngas with a molar ratio of 2, which is desired feedstock for Fischer-Tropsch (F-T) synthesis. This is due to the advantage of high catalytic stability in the co-existence of CO 2 and H 2 O oxidizing reactants and a flexible adjustment of H 2 /CO ratios by manipulating feedstock composition.…”

“…BRM is a potential replacement for other conventional reforming processes. [6][7][8] The BRM reaction mainly consists of steam methane reforming SMR (Equation [2]), water gas shift, WGS (Equation [3]) reaction, and dry methane reforming, DMR (Equation [4]). 9 BRM:…”

Coke-resistant Ni-based bimetallic catalysts for the dry reforming of methane: effects of indium on the Ni/Al2O3catalyst

“…The peak intensity of the Al 2 O 3 support was weaker than that of the Ni- or In-support catalysts, indicating that only a small number of basic sites was on the support. In general, the ability of catalysts to resist carbon deposition is correlated with the number of strong alkaline sites, 42 and as shown in Table 3, using the amount of basicity sites in the Ni/Al 2 O 3 catalysts as a comparison, that for the catalysts containing In was higher than the Ni/Al 2 O 3 catalysts, where the addition of In increased the alkalinity of the catalyst and provided a stronger basic centre for the catalyst. The 3Ni–2In/Al 2 O 3 catalysts exhibited the highest basicity and contained the most strongly basic sites (type III and IV), which was caused by the catalyst having the strongest binding affinity with CO 2 due to the electron coordination effect from the Ni–In interaction.…”

“…Catalysts with high basicity effectively assist in the adsorption and activation of CO 2 , thus providing active surface oxygen for the reaction, which can reduce the amount of carbon accumulation and maintain the catalyst activity. 42,43 Similar to CO 2 , NH 3 could be used as a probe molecule to analyse the acid sites of the catalyst. As shown in Fig.…”
