Performance and industrial application on catalytic oxidation catalyst for volatile organic compounds
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.
