Abstract
This Chapter introduces how to determine the key design parameters of the diameter-transformed fluidized bed (DFB) reactors, i.e., the diameter expanding ratio and the height of multiple reaction zones, based on the “choking” phenomenon captured by numerical investigation with multiscale CFD simulations. To achieve the steady operation in multiple reaction zones, related ancillary techniques are subsequently developed, such as the distributor installed between the first reaction zone and second reaction zone. Meanwhile, the proprietary catalysts are also being developed. The FCC process with two reaction zones, effective utilization of heavy oil and light-olefin production process are exploited in succession by using the DTFB as the core reactor.
