Laboratory Scale Fluidized Bed Reactor

A laboratory scale fluidized bed reactor was designed and fabricated successfully.

Laboratory scale fluidized bed reactor.

After 50 g of a dried catalyst was charged an air flow 200 220 or 240 l h was produced by air compressor and fed to the fluidized bed to fluidize the catalyst particles. The design of this reactor is thoroughly described. A bed section b freeboard section and c conical closure section with inlet cone. Developing a scalable model from the laboratory fluidized bed is particularly important because of the potential for.

The reactor system consists of four parts. Several relatively large laboratory scale high pressure fluidized beds designed for pyrolysis and gasification experiments have been reported in the literature. This latter process is widely used in laboratory scale systems by fluidizing the bed in a once through cycle with hcl in. Morris and keairns 1979 have described a reactor made of inconel 600 35 mm i d 330 mm long placed inside a.

The size of the laboratory scale fluidized bed reactor is 5 kw which corresponds to a fuel feeding rate of approximately 1 kg h. The size of the laboratory scale fluidized bed reactor is 5 kw which corresponds to a fuel feeding rate of approximately 1 kg h. Fluidized bed reactors fbrs are chemical reactors in which catalytic particles interact with a gas stream that is fed from the bottom such that the mixture emulsion phase behaves as a fluid. The aim of this project was to construct a laboratory scale fluidized bed reactor that simulates the behavior of full scale municipal solid waste combustors.

A bed section a. The interstitial fluid velocities obtainable in laboratory scale fixed bed reactors determine that portion of the relationship dominated by stagnant film diffusion resistance. A bed section. Catalyst particles were attrited at room temperature in the laboratory scale fluidized bed.

Thus it is important to have available fixed bed reactors capable of operating at intermediate interstitial fluid velocities to establish the relationship between 1 k. The 5 kw laboratory scale fluidized bed reactor de scribed in the article is the second generation of the reactor used by fängmark 20 21 there are several unique features about our 5 kw reactor. The design parameters which affect the performances are identified and discussed. The reactor consists of three sections.
