Combined CO2 reforming and partial oxidation of methane over mesoporous nanostructured Ni/M-Al2O3 catalyst: Effect of various support promoters and nickel loadings

Functional Improvement of NiOx/CeO2 Model Catalyst Active in Dry Methane Reforming via Optimization of Nickel Content

“…Moreover, those parameters can be controlled by the appropriate optimization of nickel loading. Similar results were found for Ni/Al 2 O 3 -CeO 2 catalysts, where the influence of nickel loading was investigated in the range of 2.5 wt% to 15 wt% and the optimal concentration was found for 10 wt of Ni [62]. An experiment to investigate the deactivation progress of the investigated catalysts required a return measurement of activity at 650 • C. A comparison of activity at the beginning of the catalytic test and after raising the reaction temperature to 800 • C is shown in Figure 8.…”

Dry reforming of HCs (methane, ethane, and propane) over a 40Ni0.75(Ce1−xFex)0.25/Al2O3 catalyst: a comparative study

“…The % conversion, % yield, deactivation factor, and the H 2 : CO ratio were calculated for the DRM reaction using the below equations, and the details for the DRE and DRP are shown in S.1 (ESI †). 39 3. Results and discussion…”

New Perspectives on Catalytic Hydrogen Production by the Reforming, Partial Oxidation and Decomposition of Methane and Biogas

“…As one of the limitations of ATDR is that addition of O 2 to the reaction mixture can lower CO 2 conversion, dual-site catalysts capable of improving CO 2 activation are of interest for the dry-reforming reaction: for example, addition of CeO 2 and ZrO 2 to a SiO 2 support for Ni catalysts was observed to remarkably include catalytic performance, providing CO 2 conversion close to the equilibrium value in a temperature range of 600-800 • C [149]. More recently, the effect of the addition of CeO 2 and ZrO 2 promoters to the alumina support for the Ni catalyst was also investigated, with cerium dioxide performing the best in terms of performance improvement [150]. Setting themselves apart from conventional thermochemical process, Fan et al [151] proposed instead an innovative design for a novel Solid Oxide Fuel Cell reactor for the cogeneration of syngas and electrical power through ATDR.…”
