چکیده انگلیسی
Hydrodynamics and kinetic reactions in a fluidised-bed MTO reactor were investigated by using CFD method. The hydrodynamics and species concentrations were considerably non-uniform in the MTO reactor. Methanol conversion rate and product yields were more sensitive to the reaction temperature and pressure than to the initial methanol content in the feedstock. A gas velocity of 2.5-3.0Â m/s and a catalyst circulation rate of 100-120Â kg/(m2Â s) were found to be ideal for the current reactor. Coke deposition significantly affected the methanol conversion rate, product distribution and species selectivity.
