摘要: A reactor model for a methanol-to-olefin (MTO) reaction system was constructed by incorporating filtered drag model, gas–solid heat-transfer and an MTO kinetic to probe large-scale behavior explore optimization. First, the efficiency of several typical models evaluated comparing predicted results with experimental data. Second, effect two significant operation parameters, namely, temperature water-to-methanol ratio, were studied based on above-mentioned model. Predictions suggested optimum catalyst residence time (∼33 min) average coke content (∼6.74%) this system. In addition, relatively high maximized ethylene production, water introduced into feed significantly attenuated deposition. This work is first conduct coarse-grid simulations using developed effective filtered-CFD coupled flow optimizat...
