Abstract

본 발명은 고정원으로부터 배출되는 배연가스중에 함유된 유해가스중 아황산가스와 질소산화물을 제거하는데 유용한 갈탄챠르 제조방법에 관한 것이다.
본 발명의 갈탄챠르 제조방법은, 원료갈탄을 유동층 반응기에 장입하고 질소, 산소 및 수중기로 이루어진 유동화가스를 공급하여 유동화시키는 한편 유동화 반응기 내부온도를 500∼800℃로 가열하여 갈탄의 열분해가 일어나도록 하여 열분해의 결과 생성된 갈탄챠르를 포집하는 공정으로 이루어진다.
본 발명의 방법에 의해 얻어진 갈탄챠르는 탈황 및 탈징성능 모두 종래의 탄소제품에 비해 우수하고 제조비용면에서도 경제적이라는 이점이 있다.
