Question

Which of the following is true for fluidized catalytic beds?

(a) They cannot be used for multi-phase chemical reactions

(b) The bulk density is a function of the flow rate through the bed

(c) They come under the category of batch reactors

(d) There is no pressure drop

The question was asked in exam.

I need to ask this question from Non topic in portion Rate Laws and Stoichiometry of Chemical Reaction Engineering

Answer 1

The correct answer is (b) The bulk density is a function of the flow rate through the bed

To explain: Fluidized catalytic beds are mostly used for multi-phase reactions, for example, cumene decomposition. They come under flow reactors. The inclusion of fluidized bed offers more resistance to flow and hence results in a pressure drop.
