Laboratory Scale Fluidized Bed Reactor

A bed section.

Laboratory scale fluidized bed reactor.

Several relatively large laboratory scale high pressure fluidized beds designed for pyrolysis and gasification experiments have been reported in the literature. The design parameters which affect the performances are identified and discussed. A bed section b freeboard section and c conical closure section with inlet cone. The reactor consists of three sections.

The interstitial fluid velocities obtainable in laboratory scale fixed bed reactors determine that portion of the relationship dominated by stagnant film diffusion resistance. 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 size of the laboratory scale fluidized bed reactor is 5 kw which corresponds to a fuel feeding rate of approximately 1 kg h. A bed section a.

The design of this reactor is thoroughly described. However the design and operation of industrial scale fluidized bed reactors for the conversion of stc to tcs is currently based on ad hoc rules of thumb and operator experience rather than on reaction engineering principles. A laboratory scale fluidized bed reactor was designed and fabricated successfully. 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 reactor system consists of four parts. 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. Morris and keairns 1979 have described a reactor made of inconel 600 35 mm i d 330 mm long placed inside a.

4 3 1 a survey of small scale high pressure fluidized bed reactors. 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. The reactor system consists of four parts. Catalyst particles were attrited at room temperature in the laboratory scale fluidized bed.
