Summary
-
1.
It has been shown that there are five zones in a model reactor having a fluidized bed and a separating heat-transfer agent; these zones differ in composition, structure of the fluidized bed, and the mechanism of the processes occurring in them.
-
2.
The concentration variations in the model studied depend on the filtration rate and the height of the mobile heat-transfer agent layer. These relationships are different for different heat-transfer agent fluidization numbers.
-
3.
The separation efficiency is determined to a considerable extent by the degree of removal (blow out) of catalyst particles from the heat-transfer agent layer by the gas flow.
-
4.
A more complete separation of the catalyst (less than 0.001%) can be obtained by using the blow-off zone.
