Improvement in fluidization quality and mass transfer rate was made to the pulsed fluidized bed for the fluidization of biomass particles without the need of inert bed materials by modifying the rectangular cross-section to a tapered bottom section to eliminate the dead-zones.
Nonideal mixing behavior of solid particles in a fluidized bed for catalytic polymerization is examined for its effects on the particle size distribution (PSD).
Such a rotating drum can be regarded as a new gasless fluidized bed for fine powders in contrast to a traditional fluidized bed, possibly leading to a considerable amount of energy savings.
The settling velocities of permeable bodies are of interest in fluid solid reactors, including gas fluidized beds, for example.
This work deals with the numerical simulation using CFD of a gasifier bubbling fluidized bed for the system composed of gas - biomass – sand.
This paper analyzes the relationship between flow structure and mass transfer in fast fluidized beds for Geldart A and B particles.
It is proven to agree well with experimental data available up to date from bubbling fluidized beds for Geldart B and D particles.
The model is applied to simulate liquid injection into the fluidized bed for conditions that were previously experimentally studied and published.
However, their hydrodynamic behaviors are quite different in the sense that the fluidized bed for MTO reactions operates in different flow regime from that of FCC, calling for new modeling for scale-up.
Spray coating of polymer latex onto fertilizer particles in a fluidized bed for producing controlled-release urea is an environment friendly technology as it does not need any toxic organic solvent.
