Membrane reactor - Wikipedia

Generally, membrane reactors can be classified based on the membrane position and reactor configuration. Usually there is a catalyst inside: if the catalyst is installed inside the membrane, the reactor is called catalytic membrane reactor (CMR); if the catalyst (and the support) are packed and fixed inside, the reactor is called packed bed membrane reactor; if the speed of the gas is high .

Fluidized bed reactor - Wikipedia

A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst possibly shaped as tiny spheres) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.

1.4 Continuous—Flow Reactors | Elements of Chemical .

Continuous-flow reactors are almost always operated at steady state. We will consider three types: the continuous-stirred tank reactor (CSTR), the plug-flow reactor (PFR), and the packed-bed reactor (PBR). Detailed physical descriptions of these reactors can be found in both the Professional Reference Shelf (PRS) for Chapter 1 and in the Visual Encyclopedia of Equipment, encyclopedia.che.engin .

Reactors - processdesign

Fixed Bed Reactors; In a fixed-bed reactor, the reagent flows over a stationary bed of packed catalyst (Towler and Sinnott, 2013). This is the most common type of reactor used for heterogeneous catalysis as long as the catalyst does not require continuous regeneration and the reaction mixture does not require high agitation (Towler, 2012).

Dynamic modelling and optimal control strategies for .

Packed bed reactors (PBR) have recently emerged as alternatives for the CLC reactor configuration. In this scheme, stationary OC particles inside a single reactor are alternately exposed to oxidation and reduction streams .An advantageous feature of the PBR scheme is the avoidance of the cyclone separator, which effectively circumvents the cumbersome task in IFBR of recovering the OC particles .

Packed-Bed Bioreactor and Its Application in Dairy, Food .

In classical chemical engineering, a common catalytic reactor is the fixed-bed or packed-bed reactor, which refers to two-phase systems in which the reaction mixture flows continuously through a stationary bed of catalyst particles or pellets. Packed-bed reactors are widely used in industrial applications,, .

Design of fixed bed catalytic reactors

which is important in the design procedure for any fixed-bed catalytic reactor. A bed of catalyst pellets is generally considered as if it were a continuous homogeneous media, and the physical properties of the packed bed or system are assigned values on the basis of a weighted average of each of the individual constituents making up the system.

Comparison between fluidised bed and packed bed reactors .

Mathematical modelling of both fluidised and packed bed reactors has been carried out. In the fluidised bed reactor, a two-phase bubbling bed model has been used in order to estimate the interaction between gas bubbles and the dense phase in the bed. Modelling in the packed bed reactor was carried out based on that used by Ranade and Evans.

packed bed bioreactor

For industrial applications, upward flow is generally preferred over downward flow because it does not compress the beds in enzyme columns as downward flow does. When gas is produced during an enzyme reaction, upward flow is preferred. A continuous packed bed reactor has the following advantages over a batch packed bed reactor: 1.
