Question

What is the role of cone shaped structure in the Du pont catalytic reactor?

(a) Gas distribution

(b) To occupy empty space

(c) To prevent attrition

(d) For better fluidization

The question was asked during a job interview.

My enquiry is from Synthesis Reactions-2 in chapter Particles and Fluidization of Fluidization Engineering

Answer 1

Correct answer is (a) Gas distribution

For explanation I would say: Cone helps in gas distribution for better gas-solid contact and eliminate gas bypassing.
