초록

본 연구에서는 울산지역의 화력발전소 및 소각로에서 발생하는 비산재, 석탄계 비산재와 폐촉매를 이용하여 수열합성, 용융합성, 용융/수열합성법에 의해 제올라이트를 합성하였다. 석탄계 비산재(F-C1와 F-C2)와 폐촉매(F-W5)는 $SiO_2$$Al_2O_3$의 함량이 60.29~89.62 wt%이며, F-C1과 F-C2는 XRD 패턴 분석에서 quartz와 mullite를 포함하고 있었다. 석탄계 비산재와 폐촉매를 이용한 제올라이트 합성은 3가지 합성방법에서 모두 가능하였다. 석탄계 비산재와 폐촉매는 용융합성법에 의해 주로 Na-A형 제올라이트(Z-C1, Z-C2와 Z-W5)로 합성되었으며, 합성된 제올라이트(Z-C1 and Z-C2)는 비산재의 CaO 성분과 합성과정에서 첨가된 Na2CO3에 의해 불순물인 calcite 피크를 형성하였다.
