Catalytic conversion modeling of methanol in dehydration reactor using Voronoi 3D pore network model

Dimethyl ether as a clean fuel has been attracted in the recent decade. It can be produced catalytic reaction of methanol dehydration. Modeling and simulation fixed-bed reactor for this process is desired to predict performance. A Voronoi 3-dimensional pore network model used study effect space on Considering morphological structure one advantages model. In study, modeling was consider mass heat transfer both catalyst scales. The effectiveness factor results scale are simulations temperature concentration performance studied. indicated that reduction flow rate increases reactants residence time consequently amount conversion. inlet had significant influence conversion middle increased from 22 34 mol/m3 when its purity decreased 99 97%.
