Design of fluidized bed reactor
WebTwo types of fluidized-bed reactors have been developed and are currently used mainly by SASOL: the circulating fluidized bed (CFB) and the fixed fluidized bed (FFB). In the CFB reactor, the fine catalyst particles are entrained by a high-velocity gas stream through a … Recent trends in the pyrolysis and gasification of lignocellulosic biomass. … WebIt was shown that modeling of a fluidized bed reactor through minimization of the Gibbs free energy will lead to an overestimation of species conversion because effects like gas …

WebA fluidized-bed reactor (FBR) is a combination of the two most common configurations, stirred tank and packed bed continuous flow reactors. It has excellent heat- and mass-transfer characteristics. In FBR, cells are attached to solids in the form of biofilm or granules.

WebThe reservoir can also be operated as a fluidized bed reactor like in a dual-fluidized bed system. The first experimental results are reported using a Geldart B sand as bed inventory. A hydrodynamic study has been carried out to verify proper control of the system. Solid circulation rates have been determined and match the design target of 1.4 g/s.
WebJun 30, 2024 · In this study, the multi-phase Eulerian–Eulerian two-fluid method (TFM) coupled with the kinetic theory of granular flow (KTGF) was used to investigate the hydrodynamics of particle flows (Geldart Group B) in a lab-scale bubbling fluidized bed.
