Coarse-grained CFD-DEM simulation of biomass gasification in a fluidized bed reactor

Fuel, 2019
Gas-solid fluidized beds play an important role in many industrial operations. However, there still is a lack of knowledge concerning the processes inside the bed, which impedes proper designing and upscaling of fluidized bed reactors.

Circulating fluidized-bed reactors

Chemical Engineering Science, 1997
Abstract This paper develops a flow and contacting model to represent a CFB. Best estimates of contacting efficiencies are presented for the turbulent, fast fluidized, and pneumatic transport regimes of the CFB. Material balances are presented, ending up with conversion equations for first-order solid-catalyzed gas-phase reactions. Four examples show
