The performance of catalytic oxidation catalyst for volatile organic compounds developed by Petrochemical Research Institute of PetroChina was evaluated,and its industrial application was investi-gated in a wastewater treatment plant of a petro-chemical company.The results showed that the coat-ing detachment rate of the active component of the self-developed catalyst was only 0.19%.When the reaction temperature was below 200℃,the reaction temperatures for the self-developed catalyst with 50%and 90%conversion rates of C6H6 were 155,176℃respectively,which were higher than that of the imported catalyst.Under the conditions of reaction temperature of 252-451℃,volume space velocity of 9 000-13 000 h-1,mass concentration of non methane total hydrocarbons(NMHC)in the in-let exhaust gas of the catalytic oxidation device of 27-1 300 mg/m3,and mass concentration of C6H6 of 10-1 000 mg/m3,the NMHC removal rate remained stable at over 97%and C6H6 removal rate remained stable at over 99%during a 100 d long cycle indus-trial operation.
