Fluidized bed membrane reactors
2014Fluidized bed membrane reactors are an extension or an improvement of a packed bed membrane reactor. The fluidized bed configuration allows a more uniform temperature due to the movement of particles even for very exothermic reactions and decreased concentration polarization.

Stability in a Denitrifying Fluidized Bed Reactor
Microbial Ecology, 2006This study evaluates changes in the microbial community structure and function of a pilot-scale denitrifying fluidized bed reactor during periods of constant operating conditions and periods of perturbation. The perturbations consisted of a shutdown period without feed, two disturbances in which biofilms were mechanically sheared from carrier particles,

Fluidized bed nuclear fission reactor
Chemical Engineering Science, 1996Abstract For the further development of nuclear fission reactors, the feasibility of a new concept is evaluated. It concerns a fluidized bed reactor in which carbon particles with a uranium core are fluidized and cooled by a high velocity pressurized helium flow.

Modeling Fluidized Bed Reactors
Catalysis Reviews, 1978Abstract Xodeling fluidized bed reactors may be described on the one hand as a never-endizrg study aesigaed to keep minds busy and revoluriona n aavtUes at a Low ebb o r on the orher hand as a task to make stmng men weep. Be thac as lt may, we are now very near solutions of reasonable finality.

Modelling of Fluidized Bed Reactors
International Journal of Chemical Reactor Engineering, 2003The fluidized bed reactor has a lot of advantages: excellent gas-solid contacting, no hot spots even with highly exothermal reactions, good gas-to-particle and bed-to-wall heat transfer and the ease of solids handling which is particularly important if the catalyst is quickly ageing.

In this chapter the characteristics of fluidized gas–solid suspensions are described, and the basic designs of fluidized bed reactors are sketched. Several modeling approaches that have been applied to described these units are outlined.

The name “fluidized bed reactors” (FBR) is a generic term and encompasses a variety of engineering systems including chemical reactors, combustors, gasifiers, calcifiers, driers, etc. The common characteristic of the FBR class of engineering systems is the presence of the solid particles that are carried by the fluid and exist in a fluidized state. The

Three-Phase Fluidized Bed Reactors
1986The particular characteristics of three-phase fluidized bed reactors have been covered in several recent reviews by Ostergaard [1], Wild [2], Epstein [3], Baker [4] and Muroyama and Fan [5]. Epstein [3] distinguished in particular the difference between three-phase fluidized beds and slurry reactors.

High-velocity fluidized bed reactors
Chemical Engineering Science, 1990Abstract There is increasing interest in high-velocity fluidized bed reactors operated in the turbulent and fast fluidization regimes. Understanding of the hydrodynamics of these fluidization regimes has improved greatly in recent years, and there are prospects for applications beyond those practiced in industry at this time.
