Abstract
The removal of polychlorinated dibenzo-p-dioxins and dibenzo-furans (PCDD/Fs) and dust from municipal solid waste incineration flue gas within a single device can improve operational efficiency and reduce costs. In this study, a catalytic filter was developed using ultrasonic immersion and polytetrafluoroethylene (PTFE) membrane fixation, combining a blank PTFE and VOx/TiO2 catalyst. Chlorobenzene (CB) and furan were selected as model molecules for PCDD/Fs. A series of VOx/TiO2 catalysts were synthesized through a mechanochemical method, with different types and ratios of components tested. Among these catalysts, the VWMoTi catalyst demonstrated the highest CB removal efficiency (RE), reaching over 85% at temperatures below 200 °C. The VWMoTi catalyst was impregnated into a PTFE filter for the catalytic combustion of CB and furan. The process parameters, including the catalyst loading and catalyst particle size, were analyzed. The physicochemical properties of the catalytic filter were extensively characterized. The catalytic activity of CB, furan, and dust removal performance of the catalytic filters was investigated. At 240 °C, the RE values of CB and furan were 70.82% and 100%, respectively, whereas the RE of dust reached 99.99%.
