Numerical Simulation of Hydrodynamics and Heat Transfer in a Reactor with a Fluidized Bed of Catalyst Particles in a Three-Dimensional Formulation

Applied Sciences
The hydrodynamics and heat transfer in a reactor with a fluidized bed of catalyst particles and an inert material were simulated. The particle bed (the particle density was 2350 kg/m3, and the particle diameter was 1.5 to 4 mm) was located in a ...

Minimum Fluidization Velocity of Palm Kernel Cake Particles in Fluidized Bed Fermenter

Journal of Applied Sciences, 2007
This study measured the minimum fluidization velocity of Palm Kernel Cake (PKC) particles. PKC was used as it is a potential substrate in solid state fermentation. A laboratory scale fluidized bed reactor has been fabricated for this investigation. Minimum fluidization velocity (Umf) for sand particles was initially tested to ensure the workability of ...

FLUIDIZATION BEHAVIOR OF WOOD/SAND MIXTURES

Maderas: Ciencia y Tecnología, 2004
In conversion of biomass to secondary energy carriers, several routes are possible, such as gasification, combustion and pyrolysis. In many of these processes it is necessary or advantageous to dry the biomass before further processing.
