the fluidized bed. Due to the opaque nature of a fluidized bed system, noninvasive X-ray techniques are often used to visualize and obtain valuable data regarding the internal flow structures of the fluidized material. This research determines how fluidized bed hydrodynamics are influenced by different experimental conditions. reactor design, optimization and experimental data interpretation in a cost-effective fashion. In this work, a fluidized bed reactor model for biomass fast pyrolysis was developed and applied to the Bell’s Corners Complex (BCC) fluidized bed fast pyrolysis unit located at NRCan CanmetENERGY (Ottawa, Canada) for testing and validation.

Gas-solid fluidized bed dryers are used in a wide range of industrial applications. With applying computational fluid dynamic (CFD) techniques, hydrodynamics of a two-dimensional nonreactive gas-solid fluidized bed dryer was investigated. A multifluid Eulerian model incorporating the kinetic theory for solid particles was applied to simulate the unsteady state behavior of this dryer and ... with the fuel [7]. In addition, the reactor configurations, such as packed or moving bed, bubbling bed, and fast fluidized bed, also have an influence on the system behavior. These fluidized bed configurations are determined by the particle size and velocity of the injection gas. Based on

experimental data for realistic gas -solid fluidization in a full- loop circulating fluidized bed system. The comparison reveals good agreement with respect to pressure drop and system component inventory height in the standpipe. In addition, the effect of different drag laws applied within the hydrodesulfurization reaction in fixed bed reactor and the results indicate that the reaction kinetics are not affected by pore and film diffusion limitations. The results of the comparison between the two reactors indicate that a low conversion was obtained in a fluidized bed than in fixed bed over the range of conditions studied.
