Gas Hydrodynamics of a Novel High-Speed MTO Loop Reactor: The Bypassing and Backmixing Along with Residence Time Distribution

摘要

Methanol to olefins (MTO) was an attractive technique to solve such problems as limited oil resource and increasing olefins demands. Many institutions and companies have developed different MTO reactors for industry application. Most of them chose turbulent fluidized bed as the reactors. However there exists a large extent of gas backmixing and long residence time in such reactors, which is detrimental to the MTO reaction.
