Experts, most of the MTO reactors developed in China are of the fluidized-bed type, along with DMTO, FMTP, and Sinopec’s MTO technology; most of these technologies have undergone pilot-scale testing. From the perspective of reactor design, are there any issues between these reactors and the regenerators? How can catalyst regeneration be carried out promptly after the catalyst becomes deactivated in a fluidized bed or a turbulent bed? How is the catalyst circulation rate determined? . Note $ # , $ $
Go and learn about FTP in oil refining first, and then you’ll know how to regenerate it!
Fixed-bed reactors are easy to scale up in design, have well-developed theoretical research, and a large number of industrial applications; however, the catalysts are difficult to replace and heat transfer is poor. Fluidized bed reactors are easy to control in terms of temperature and facilitate on-line regeneration, but the design and simulation of such reactors are very complex. There is still no effective theoretical framework for the study of fluid dynamics in these reactors. Catalyst wear is severe, and scale-up relies mainly on empirical approaches. However, FCC has provided a great deal of experience for the application in fluidized beds in industry.
You can learn about the process of producing gas through pyrolysis; the fluidization in MTO is more or less similar to that. The circulation rate is related to both the feed and carbon fixation.
