Fluidized bed reactor
专利汇可以提供Fluidized bed reactor专利检索，专利查询，专利分析的服务。并且PURPOSE: To produce stationary a circulating flow in a fluidized bed, and to inhibit the generation of channeling and coarse grains formation, by installing numbers of dispersing devices for fluidized gas blown into the fluidized bed and regulating the speed of the gas blown in to several values different with each other.
CONSTITUTION: A lower portion of a decomposing furnace 1 is provided with numbers of gas dispersers 2, 3; gas chambers 4, 5 are installed beneath the dispersers, and super heated steam is supplied through fluidizing gas feed pipes 6, 7 while each changing the flow rate. Thus, grain rising portions 11 and grain falling portions 12 are formed up in a fluid layer 10, and stationary circulation flows are formed in the fluidizing bed 10. Heavy gydrocarbon, etc. are supplied to an upper portion of the disperser 3 from a raw material feed pipe 21 or 22 and pyrolyzed, and one portion is converted to light weight and discharged to the outside of the system through cyclones 25, 26. A residual, solid carbonized product (coke) is accumulated on the surface of fluuidized particles, extracted and again returned to the fluidized bed 10 as a heat source for the decomposing reaction. A rate of conversion is kept highly by means of the fluidized bed 10.
