Abstract:
1. A process for treating a contaminated gas, comprising the following steps: continuously introducing a contaminated gas containing volatile organic compounds into a reactor; treating the contaminated gas by allowing the contaminated gas into the reactor to contact a metal oxide catalyst and an oxidant for a period of time to decrease the concentration of the volatile organic compounds; continuously emitting the treated gas from the reactor; continuously monitoring a value selected from the group consisting of the concentration of the organic compounds of the emitted gas, the concentration of the oxidant of the emitted gas, and a combination thereof; and controlling the oxidant feeding amount according to the monitored value, wherein the contaminated gas to be introduced has a humidity between 20% and 100% and a temperature of T° C., and the contaminated gas is heated to a temperature between (T+5)° C. and (T+70)° C. in the treating step.
