Abstract

본 발명은 촉매의 조기 성능열화를 방지할 수 있는 공기분리방법 및 그에 사용되는 장치에 관한 것으로서, 압축공기를 제2흡착탑(5)에 도입하여 공기중의 탄산가스와 물을 흡착제거하고, 상기 제2흡착탑(5)을 경유한 공기를 심랭액화분리하여 질소와 산소로 나누는 공기분리방법은 상기 압축공기를 제2흡착탑(5)에 도입함에 앞서 공기압축시의 압축열에 의해 승온한 압축공기를 냉각하여 강온시킨 후 제1흡착탑(4)에 도입하여 압축공기중의 수분을 흡착제거하고, 이어서 상기 제1흡착탑(4)을 경유한 공기를 촉매탑(9)에 통하여 공기중의 일산화탄소 및 수소를 산화하는 것이며, 촉매탑에 내장된 촉매가 조기에 성능열화하는 일이 없고, 또 장기적인 유지보수가 불필요하고 싼 가격으로 제공되는 것을 특징으로 한다.
