英文摘要Particle scale information of commercial fluidized beds is important for its design and optimization, e.g., the catalyst performance evolution along time. However, it is difficult to be obtained by in-situ measurements or continuum-based numerical simulations due to the limited accuracy in space and time. Thus, the newly developed reaction model for methanol-to-olefins (MTO) is integrated into the coarse-grained discrete particle method (EMMS-DPM) to study the evolution of coke content distribution on the catalyst. The main gaseous products of the commercial MTO reactor are well predicted. Then, the operation optimization for a commercial MTO reactor is conducted by changing the annual processing capacity and the size distribution of catalysts. Results show that the reactor operation is slightly more difficult when the annual processing capacity is increased by 20%, and increasing the mass fraction of finer catalyst may result in more homogeneous MTO reaction and reduce the energy consumption.
