Low-temperature catalytic conversion of greenhouse gases (CO2 and CH4) to syngas over ceria-magnesia mixed oxide supported nickel catalysts

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

“…14,15 However, undesired catalyst deactivation due to carbon formation followed by metal sintering at high temperatures was found to be present in DMR. 16,17 As a result, a combination of these reactions (SMR and DMR) generates syngas with a suitable molar ratio for the production of clean fuels by F-T synthesis.…”

Thermodynamic assessment of the stability of bulk and nanoparticulate cobalt and nickel during dry and steam reforming of methane

“…As CO 2 is a weaker oxidant, DRM is even more endothermic than SRM and consequentially requires elevated operation temperatures in the range of 700-1000 C for industrial application. 7 Nevertheless, thermocatalytic low temperature reforming (#500 C) has been successfully demonstrated in the literature for SRM and DRM, [10][11][12] but an efficient conversion to synthesis gas is strongly limited by thermodynamic constraints. 1 The typically elevated operation temperatures in combination with an oxidising reaction mixture including hydrocarbons may cause rapid catalyst deactivation via coking and sintering, which are typically accelerated at elevated temperatures.…”

Catalytic Upgrading of Clean Biogas to Synthesis Gas

“…Carbon dioxide can be then converted to CO while the adsorbed oxygen is available to provide a pathway for carbon oxidation. As demonstrated by Al-Swai et al [109], a CeO2-MgO binary oxide (15:85 wt/wt) can improve Ni activity in the DR at low temperature. The authors report that, although further improvements are needed regarding the stability of the catalyst, a 20 wt.% Ni/CeO2-MgO catalyst shows remarkable CH4 and CO2 conversions at 400 °C (20%, GHSV = 36,000 mL g −1 h −1 ), higher than those registered for similar catalysts tested at higher temperatures [110,111].…”
