Semibatch reactor is preferred, when a/an__________________?
Correct answer: B. All A., B., and C.
- A. A highly exothermic reaction is to be controlled
- B. All A., B., and C.
- C. A gas is to be reacted with liquid (e.g. hydrogenation of fat)
- D. Undesirable side reaction (at high concentration of one of the reactants) is to be avoided
Explanation
Semibatch operation permits gradual addition of a reactant, helping control heat release and preventing high reactant concentrations that promote side reactions. It is also useful for gas-liquid reactions such as hydrogenation, so all three statements apply.
