인쇄공정에서 배출되는 VOCs 종에 따른 촉매연소특성 조사

다국어 초록 (Multilingual Abstract)

In this study, the catalytic combustion characteristics according to the type of volatile organic compounds (VOCs) emitted from the printing process were investigated. The combustion characteristics were analyzed with the exothermic behavior on the catalyst bed during low-temperature combustion ignition using catalysts for methyl ethyl ketone (MEK), ethyl acetate (EA), and methanol(MeOH) among VOCs used in the gravure printing process. As a result of comparing and analyzing the temperature change in the inlet, middle, and outlet portions of the honeycomb catalyst packed in the reactor for each initial ignition temperature, it was confirmed that EA, MEK and MeOH were ignited above 250 °C, 270 °C, and 200 °C, respectively. It was confirmed that the differentiation of ignition and operating temperature is required depending on the type of VOCs in the catalytic combustion process in order to prevents to acting as a precursor of ultra-fine dust after discharged to the atmosphere of the solvent used in the printing process. It was concluded the deactivation of the combustion catalysts may be caused by the formation of carbon by incomplete combustion when MEK and EA were ignited at low-temperature.
