For high conversion in a highly exothermic solid catalysed reaction, use a ______________ bed reactor?
Correct answer: B. Fluidised bed reactor followed by a fixed
- A. Fixed
- B. Fluidised bed reactor followed by a fixed
- C. Fixed bed reactor followed by a fluidised
- D. Fluidised
Explanation
A fluidised bed provides effective heat removal and limits temperature rise in a highly exothermic reaction, while the following fixed bed gives more plug-flow contact and higher final conversion. Thus, the usual arrangement is fluidised bed followed by fixed bed.
