Elements of Chemical Reaction Engineering

Another type of catalytic reactor in common use is the fluidized-bed reactor, which is analogous to the CSTR in that its contents, though heterogeneous, are well mixed, resulting in an even temperature distribution throughout the bed. The fluidized-bed reactor can only be approximately modeled as a CSTR; for higher precision it requires a model .

CFD simulation for two-phase mixing in 2D fluidized bed .

Jan 22, 2009 · Two-phase (solid and gas) 2D fluidized bed reactor's flow pattern was investigated. Computational fluid dynamics (CFD) simulation results were compared with those obtained experimentally. The CFD simulation is carried out using commercial software "Fluent". Experiment is carried out in a fluidized bed containing spherical glass beads of diameter 300–350 μm.

Methanation in a fluidized bed reactor with high initial .

An extensive experimental study on the methanation reaction was carried out in a gas–solid fluidized bed reactor at 320 °C with a stoichiometric ratio of H 2 /CO=3. By means of spatially resolved measurements of the axial gas species concentration and temperatures along the fluid bed the effects of different catalyst loadings, gas velocities and dilution rates were observed and analyzed.


effluent. The sand media was added to the FBRs to yield a settled bed volume of approximately 1.1 L. The sand bed was fluidized to approximately 1.45 L using a peristaltic pump on the recycle line. The reactor pH was controlled by direct addition of caustic with a variable set point controller.
