Fluidized beds are commonly used in catalytic cracking processes of heavy oils. The limitations on the fluidized bed is that the particle size must be small (<300um), and be able to withstand the attrition of hitting other particles and the walls of the reactor.
Fluidized-bed reactors. Fluidized-bed reactors are theoretically an excellent reactor type choice for highly exothermic reactions, such as the FT reaction. Fluidized-bed reactors offer a much higher efficiency in heat exchange, compared to fixed beds, and better temperature control, due to the turbulent gas flow and rapid circulation.
simulation procedure of a bubbling fluidized bed reactor, where three different meshing approaches were applied. A 180° symmetric cylindrical reactor was used in all models and a special consideration has been given to the effect of the fluidization medium (air) velocity profile to the sand-bed …
gasoline and fluidized-bed reactors for making phthalic anhydride debuted in the 1940s. Today, about three-quarters of all polyolefins are made by a fluidized-bed process. The development of a specialized zeolite catalyst for cracking heavy oil into various fractions enabled the com-mercialization of the FCC circulating fluidized bed. In this
In a bench-scale, stainless steel reactor, experiments were carried out to investigate fluidized bed behavior by means of on-line process control. The non-catalytic thermal decomposition of sodium hydrogen carbonate to sodium carbonate, carbon dioxide and water was used a model reaction.
Fixed-bed Reactor Fixed-bed reactors have long been used in process industries. They contain catalyst, typically in pellet form, packed in a static bed. The syngas is then passed through the bed, where the reactions are induced as the gases contact the catalyst.
A fluidized bed gasifier is a back-mixed or well-stirred reactor in which there is a consistent mixture of new coal particles mixed in with older, partially gasified and fully gasified particles. The mixing also fosters uniform temperatures throughout the bed. The flow of gas into the reactor (oxidant, steam, recycled syngas) must
