advantages of fluidized bed reactor

Fluidized Bed Reactor: Heterogeneous reactions; like a CSTR in that the reactants are well mixed . Fluidized Bed Reactors Parr Fluidized Bed Reactors are used extensively in the chemical process industries. They find broad use in the petroleum and petrochemical industries, as well as numerous chemical industries. 1. Applying a coating to small particles can be done in a fluidized bed reactor [1]. A high conversion with a Compared to packed bed, a fluidized bed has notable large throughput is possible with this type of reactor. the main distinction is that the gas rate.If the gas rate of a bubbling fluidized bed will increase, at some Location the force exerted on the particle are enough to move it upwards, carrying it outside of the bed. Introduction The earliest fluidized bed reactors used for the catalytic cracking of hydrocarbons dating from the early 1940's operated at high superficial gas velocities now associated with the regime of fast fluidization. Fluidized bed reactor 17. Thus the fluidized bed reactor provides a close idealization in gas-solid contactors for high heat transfer rates, which is needed to ensure isothermal operation in a reactor . 2. The advantages and disadvantages of fluidized bed reactors are given by Kunii and Levenspiel [1] with themain advantages being: • Easily controlled operating due to liquid like behavior of particles. Good mixing. Current Applications for Fluidized Bed Reactors FBRs are everywhere in the Process Industries. Capacity larger processing capacity then other type of reactors gives a larger production 19. Good uniformity of temperature. A circulating fluidized-bed (CFB) reactor is extremely the same as a bubbling fluidized-bed reactor. The advantages of fluidized bed have been embodied in many heterogeneous catalytic reactions [21–25]. Kinds of Phases Present: Usage: Advantages: Disadvantages: 1. This is advantageous when the solids […] (a) Packed or Fixed Bed: It consists of a bed of stationary particles on a perforated grid or distributor plate, through which gas is flowing. Fluidized Bed Reactor - Basic Mechanism, Mass Transfer in Fluidized Beds, Reaction Behaviour in a Fluidized Bed, Mole Balance on the Bubble, the Cloud, and the Emulsion, Advantages & Disadvantages, Current Applications of FBR. 2.1.Some Advantages of Fluidized Bed Reactor One advantage of using fluidized bed reactor as a dryer is the close control of conditions so that predetermined amount of free moisture may be left with the solids and to prevent dusting of the product during subsequent … The advantages and disadvantages of fluidized bed reactors are given by Kunii and Levenspiel [1] with themain advantages being: • Easily controlled operating due to liquid like behavior of particles. Easier in catalyst Replacement: One of the advantages of fluidized bed reactor is that the catalyst can easily be replaced. Applying a coating to small particles can be done in a fluidized bed reactor [1]. Advantages 18. The distinguishing feature of a fluidized bed reactor is that the bed of solid particles or catalyst is supported by an up flow of gas. This reactor provides easy loading and removal of catalyst. (c) Fast or Circulating Fluidized Bed. this case is named elutriation. … Such advantages such as better control of temperature, no hot reactors inherently possess excellent heat transfer and spot in the bed, uniform catalyst distribution and longer life mixing characteristics.
