Abstract: The working principle，the present research and the development of the fluidized bed reactors for organosilicon monomer synthesis were discussed in this paper. In addition，the advantages and disadvantages of existing interior heat transfer structure and gas distributor were presented. On this base，a new type of fluidized bed reactors for organosilicon monomer were discussed，as well as its advanced two level of disk conduction oil distributor and double cone-diversion gas distributor in details. This new type of device，representing a new direction for the fluidized bed reactors，has the following characteristics：low energy consumption，adopting technology for catalyst directly back to bed. Besides，the conducting-heat oil flows once-through in the figure-pipe bundles multiply，and absorbs heat uniformly.
