Zusammenfassung
The potential of a multi-component distributed reactant dosing via membranes was investigated including an internal reactant recycling for enhancing selectivity and yield in networks of parallel and series reactions. In a preliminary theoretical feasibility study was found, that optimal local concentrations of all reactants involved could be adjusted to improve selectivity and conversion of the desired intermediate product. These results were evaluated in a case study. The oxidative dehydrogenation of propane to the kinetically limited intermediate product propylene was considered using a VOx/γ-Al2O3 catalyst. Kinetic equations and parameters were derived initially. Compared to a single-component dosing of O2 via membranes, the yield of propylene could be almost trebled by a controlled simultaneous dosing of oxygen and propane including.
