The Modeling of the Oxidative Coupling of Methane

In the conventional view, since we are not able to express the system degrees of freedom variations at different locations, there exists no option, other than doing experiments, to access the relations among the system ruling parameters. Experimental correlations so obtained are valid, only within the boundries of measured parameters, hence cannot over all requirements. Using the computational fluid dynamics (CFD), the degrees of freedom variations at all locations and all times are accessible. This ability results from the simultaneous solution of the continuity equations, applied on small region of the system. In this investigation, the oxidative coupling of Methane modeling ,which is one of the direct methane conversion processes, is studied. The desirable product of this process is Ethylene. By simultaneous solution of reaction equations, using the FLUENT software, the temperature effects on the Methane percent conversion, the Oxygen percent conversion and the reaction selectivity were investigated. The aforementioned solution was fulfilled at 1073 and 1123 degrees of Kelvin, which have maximum reaction efficiencies.
