State whether the following is true or false.
Catalyst deactivation is usually allowed for by raising the temperature over the run.

  • A.True
  • B.False
  • C.True only at large scales
  • D.False only at small scales

Answer: A

The extra rate compensates for the lost activity and holds conversion steady, and the end of run temperature is what limits the cycle. Raising it too far accelerates sintering and coking further. End of run temperature limits the cycle.
