When carbon deposition occurs in the catalyst, the oxygen content in the flue gas drops rapidly or reaches zero.
D: drops rapidly or returns to zero. －－－－－－－－－－－－－－
If carbon accumulates, oxygen consumption increases and the oxygen content in the flue gas decreases; choose C
When carbon deposition occurs in the catalyst, the oxygen content in the flue gas ( D ). A、Rising B、Unchanged C、Slowly declining D、Rapidly declining or returning to zero
