Abstract

This study focuses on developing catalysts for the removal of toluene produced from paint booth. Toluene is one of the major VOC in painting, coating process. Pd catalysts have been used in hydrogenation oxidation and low temperature combustion reaction for toluene removal. Pd catalysts, even though it is very precious and expensive. Therefore, the prepared catalysts from minimizing the amount of Pd ratio (0.1~1.0wt%) were measured. As a result, 1.0wt% Pd(R) catalyst under all conditions showed the highest activity. These results may suggest that the catalytic activity is related to Pd dispersion according sintering atmosphere and Pd ratio in the manufacturing process through the analysis of SEM, XRD.

본 연구는 VOC 배출원 중 도장, 인쇄 공정에서 주요 발생물질인 톨루엔을 저온 분해할 수 있는 귀금속 팔라듐촉매 개발에 목적을 두고 있다. 팔라듐은 톨루엔 제거에서 활성이 우수하지만 비용이 높다. 따라서 실용성의 방안으로 Pd 담지량의 최소화 비율(0.1~1.0wt%)로 제조한 촉매의 활성을 측정하였다. 그 결과 1.0wt% Pd(R) 촉매가 모든 조건에서 가장 높은 활성을 나타내었다. 이는 SEM 촬영과 XRD 분석을 통해 촉매 제조과정에서 Pd의 담지량 및 소성 분위기에 따른 분산 형태와 연관이 있는 것으로 사료된다.
