Application of VOCPlus catalyst in tail gas treatment of synthetic rubber

Abstract

The VOCPlus type catalytic oxidation catalyst developed independently by Shanghai Donghua Environmental Engineering Co Ltd was used to evaluate the catalytic performance and investigate the actual application effect, taking the tail gas treatment system of styrene-butadiene-styrene block copolymer unit of 100 kt/a as the research object. The results showed that the VOCPlus type catalytic oxidation catalyst had the characteristics of low ignition temperature, good high-temperature stability 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 operation for more than 1.5 a, meeting the requirements for long-term operation of the exhaust gas treatment system.
