Simulation of a Solid Oxide Fuel Cell with External Steam Methane Reforming and Bypass
Fuel flexibility is a significant advantage of solid oxide fuel cells (SOFCs) and can be attributed to their high operating temperature. The eligibility of a combined heat and power (CHP) system has been investigated as a new power generation methode, in this study. Natural gas fueled SOFC power systems via methane steam reforming (MSR) yield electrical conversion efficiencies exceeding 50% and...
متن کاملOxidative Coupling of Methane to Ethylene Over Sodium Promoted Manganese Oxide
Manganese oxide catalyst promoted with sodium and supported on silica exhibits fairly good activity and selectivity towards the synthesis of ethylene from methane at the optimum operating conditions. Methane and oxygen were fed into a tubular fixed bed reactor packed with catalyst under atmospheric pressure. The effects of temperature, residence time and feed composition on conversion, selectiv...
متن کاملModeling the Performance of a Tubular Solid Oxide Fuel Cell
In this paper, we develop two computational models for the electrical performance of the tubular solid oxide fuel cell designed by Siemens Westinghouse Corporation. The first model makes simplifying assumptions for activation and concentration polarizations and obtains an analytical solution. In the second procedure, we allow the polarizations to vary with the current density and solve the equa...
متن کاملOxidative coupling of methane in a mixed-conducting perovskite membrane reactor
Ionic-electronic mixed-conducting perovskite-type oxide Lao6Sro.4Coo.sFeo203 was applied as a dense membrane for oxygen supply in a reactor for methane coupling. The oxygen permeation properties were studied in the po,-range of 10-3-1 bar at 1073-1273 K, using helium as a sweeping gas at the permeate side of the membrane. The oxygen semi-permeability has a value close to 1 mmol m ~ s ~ at 1173 ...
متن کاملTAP reactor investigation of methane coupling over samarium oxide catalysts
The adsorption and reaction characteristics of a Ba/Sr/Sma03 catalyst for methane coupling has been investigated using the TAP (Temporal Analysis of Products) reactor system. Puhed adsorption experiments using methane, oxygen and krypton at temperatures ranging from 17°C to 300°C show that the transient response of methane is similar to that of Kr and is either not adaorbed, or weakly adsorbed ...
