Thus, the benefits of using fluidized-bed technology can easily outweigh the disadvantages, especially for processes requiring catalyst circulation or superior heat transfer orTHE PERFORMANCE OF A THREE-PHASE FLUIDIZED BED REACTOR,The Performance of a Three-Phase Fluidized Bed Reactor 221 fed in during a period of three days until reaching 18 L/h Two different recycling and aeration flow ratesFluidization - SlideShare,Theory of Fluidized bed system – Concept Fluidization is a condition in which the solid particles are supported by drag forces caused by the gas phase passing through the interstices among the particles at some critical velocity It is an unstable condition in that the superficial gas velocity upward is less than the terminal settling velocity of the solid particles The gas velocity is not

Fluidized bed reactor - Wikipedia

Basic principles The solid substrate (the catalytic material upon which chemical species react) material in the fluidized bed reactor is typically supported by a porous plate, known as a distributor The fluid is then forced through the distributor up through the solid materialFluidized bed reactorppt | Fluidization | Nature,Scribd is the world's largest social reading and publishing siteFLUIDIZATION - slidesharenet,Beds under these conditions are called turbulent beds(05) With further increases of gas velocity, eventually the fluidized bed becomes an entrained bed in which we have disperse, dilute or lean phase fluidized bed, which amounts to pneumatic transport of solids (06)
