  2. Fluidized bed reactor - Wikipedia

    en.wikipedia.org/wiki/Fluidized_bed_reactor

    The first fluidized bed gas generator was developed by Fritz Winkler in Germany in the 1920s. [2] One of the first United States fluidized bed reactors used in the petroleum industry was the Catalytic Cracking Unit, created in Baton Rouge, LA in 1942 by the Standard Oil Company of New Jersey (now ExxonMobil).

  3. Fluidized bed - Wikipedia

    en.wikipedia.org/wiki/Fluidized_bed

    Taking an example from the food processing industry: Fluidized beds are used to accelerate freezing in some individually quick frozen (IQF) tunnel freezers. These Fluidized bed tunnels are typically used on small food products like peas, shrimp or sliced vegetables, and may use cryogenic or vapor-compression refrigeration. The fluid used in ...

  4. Circulating fluidized bed - Wikipedia

    en.wikipedia.org/wiki/Circulating_fluidized_bed

    In designing a circulating fluidized bed, with constant temperature distribution for either endothermic or exothermic reactions, in order to determine the appropriate design for cooling or heating of the circulating fluidized bed reactors, a good approximation of heat transfer rates are necessary for better control so that the reactor can ...

  5. Ebullated bed reactor - Wikipedia

    en.wikipedia.org/wiki/Ebullated_Bed_Reactor

    Ebullated bed reactors are a type of fluidized bed reactor that utilizes ebullition, or bubbling, to achieve appropriate distribution of reactants and catalysts.The ebullated-bed technology utilizes a three-phase reactor (liquid, vapor, and catalyst), and is most applicable for exothermic reactions and for feedstocks which are difficult to process in fixed-bed or plug flow reactors due to high ...

  6. Fluid catalytic cracking - Wikipedia

    en.wikipedia.org/wiki/Fluid_catalytic_cracking

    The reactor is a vessel in which the cracked product vapors are: (a) separated from the spent catalyst by flowing through a set of two-stage cyclones within the reactor and (b) the spent catalyst flows downward through a steam stripping section to remove any hydrocarbon vapors before the spent catalyst returns to the catalyst regenerator.

  7. Fluidization - Wikipedia

    en.wikipedia.org/wiki/Fluidization

    The fluidized catalyst particles are shuttled between the fluidized bed reactor and a fluidized bed burner where the coke deposits are burned off, generating heat for the endothermic cracking reaction. By the 1950s, fluidized bed technology was being applied to mineral and metallurgical processes such as drying, calcining, and sulfide roasting.

    The nuclear power industry is increasingly looking to smaller reactors, which run on HALEU. These reactors can last longer than conventional ones and fit into smaller spaces — making them more ...

  9. Fluidized bed combustion - Wikipedia

    en.wikipedia.org/wiki/Fluidized_bed_combustion

    Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials ( sand , limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.
