Technical Field

[0001] The utility model relates to the technical field of fluidized bed reactor protection, in particular to an anti-coking device for a fluidized bed reactor. Background Art

[0002] Currently, two types of reactors have been developed: fixed bed and fluidized bed. The methanol-to-gasoline process developed by Mobil in the early days, the MTP process of Lurgi, and the methanol-to-aromatics project of the Shanxi Coal Chemistry Institute of the Chinese Academy of Sciences all adopted the fixed bed process. Mobil later developed the fluidized bed process with the support of the US and German governments, the methanol-to-olefins (MTO) industrialized by the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences, and the methanol-to-aromatics project (MTA) industrialized demonstration by Tsinghua University all adopted the fluidized bed process. The process selection is generally based on the performance of the catalysts they have developed and the reactor technology they have mastered.
