Question

What is the advantage of fluid bed catalyst in methanation?

(a) Fast reaction

(b) High temperature

(c) Remove heat

(d) Supplies heat

This question was posed to me in an online interview.

I'm obligated to ask this question of Processes of Fischer Synthesis topic in section Hydrocarbon Synthesis and Hydroformylation of Unit Processes

Answer 1

Right choice is (c) Remove heat

To explain: The advantage of this technique is that only small amounts of end gas need be recycled to remove the heat of reaction because of the relatively high heat transfer obtained in the fluid bed.
