The VOCPlus type catalytic oxidation catalyst developed independently by Shanghai Donghua Environmental Engineering Co Ltd was used to evaluate the catalytic performance and in-vestigate the actual application effect,taking the tail gas treatment system of styrene-butadiene-styrene block copolymer unit of 100 kt/a as the research ob-ject.The results showed that the VOCPlus type catalytic oxidation catalyst had the characteristics of low ignition temperature,good high-temperature sta-bility and strong hydrothermal stability.The mass concentration of non-methane total hydrocarbons at the reactor outlet was 6.2 mg/m3 and the removal rate of non-methane hydrocarbons remained above 99%under the conditions of catalyst inlet temperature of about 372 ℃,reaction temperature of 428 ℃ and a mass concentration of non-methane hydrocarbons of 1 500 mg/m3.The system had been in stable opera-tion for more than 1.5 a,meeting the requirements for long-term operation of the exhaust gas treatment system.
