“…Heterogeneous catalysts are majorly employed in steam reforming reactions so the reactants can readily pass through a solid catalyst bed [24]. These catalysts are categorized into three types: oxide catalysts, noble metal catalysts and base metal catalysts as illustrated in Table 2 [5].…”

Khzouz, M. et al. (2013). Characterization and activity test of commercial Ni/Al203, Cu/ZnO/Al203 and prepared NieCu/Al203 catalysts for the hydrogen production from methane and methanol fuels. A comprehensive comparison between these two fuels is established in terms of reaction conditions, fuel conversion, H2 selectivity, CO2 and CO selectivity. The prepared catalyst showed low selectivity for CO in both fuels and it was more selective to H2, with H2 selectivities of 99% in methane and 89% in methanol reforming reactions. A significant objective is to develop catalysts which can operate at lower temperatures and resist deactivation. Methanol steam reforming is carried out at a much lower temperature than methane steam reforming in prepared and commercial catalyst (275-325 o C). However, methane steam reforming can be carried out at a relatively low temperature on NieCu catalyst (600-650 o C) and at higher temperature in commercial methane reforming catalyst (700-800 o C). Commercial Ni/Al2O3 catalyst resulted in high coke formation (28.3% loss in mass) compared to prepared NieCu/Al2O3 (8.9%) and commercial Cu/ZnO/Al2O3 catalysts (3.5%).

“…Potassium was proved to be the most effective promoter in suppressing coke formation in ATR. The addition of K not only lowers the coking tendencies of alumina supports, but also prevents nickel from catalyzing the decomposition reactions [133]. Lanthanum was added as a promoter to improve the catalytic activity of nickel.…”

AbstractA three-dimensional, unstructured, multi-species reacting flow solver is developed to model solid oxide fuel cells (SOFCs) as well as catalytic reactors. The finite volume based solver utilizes density-based method to solve the coupled system of governing equations. Numerical results for both SOFC and reactor obtained using the inhouse code are compared with the experimental results from the literature for validation purposes. Effects of mass flow rates of incoming species on performance of SOFC as well as catalytic reactor are investigated. Two different methods namely direct differentiation and discrete adjoint method are implemented in the code to compute sensitiv...
