고분자 담지제에 의한 청주공단내 공장배기가스의 효율적 처리기술에 관한 연구(Ⅱ) : 고분자 담지제의 흡착실험을 중심으로 = Study on Effective Treatment of Waste Gases in Chung - Ju Industrial Complex with Polymeric Absorbent ( Ⅱ )

다국어 초록 (Multilingual Abstract)

Two major hazardous gases. SO_x and NO_x are emissioned from fossile fuels SO_x has been removed when oil is refined but NO_x hasn't. So NO_x is very serious problem in air pollution now. There are several technologies to remove NO_x e.g. cooling method, scrubbers method, combustion method, polymer membrane method and adsorbent methods. Polymer membrane and adsorbent methods have good economic merit in removal systems of low content hazard gases. Traditional absorbents are prous silicas aluminas, active carbon and zeolites. But these absorbents act only physisorption which has less removal performance than chemisorption. In this study, polymeric absorbent which has chemisorption as well as physisorption was analyzed about chemical structure and experimented about optimum operation conditions. The results showed that the chemical structure of the polymeric absorbent was expected as polystyrene having -N-CH₂COOH absorpent was revealed about 310㎡/g. The molar ratio of absored NO to charged NO in absorption experiments was shown 60% of the polymeric absorbent and 45% of zeolite absorbent at 30℃.
