초록

본 연구에서는 바이오매스의 탄화공정 시 발생되는 목초액을 응축성 가스물질의 전구물질로 이용하여 발생되는 응축성 가스상 오염물질을 제거하기 위하여 액체상 흡착제중 실리카 전구물질인 HMDS의 주입조건에 따른 응축성물질의 입경분포 변화특성을 명확히 파악하고자 하였다. 응축성 가스상 물질을 입자화시켜 제거하기 위하여 액체상 흡착제인 HMDS를 이용할 경우, 흡착제의 주입량, 체류시간 및 가열온도, MFC 유량 등의 적절한 조절로써 입자화 크기를 조절할 수 있었다. 특히 실리카 전구물질을 도입시 끓는점, 밀도(비중), 분자량 등의 물리화학적 특성을 고려하면, 발생되는 응축성 물질을 효과적으로 입자화시켜 제어 가능할 것으로 판단된다.

In this study, we were clearly identify the behaviour characteristics on particle size distribution of a condensing species by injection condition of HMDS (Hexa Methyl Di-Silazane, silica precursor that is one of liquid adsorbents) to remove condensing gaseous species as using pyroligneous liquor generated during carbonization process of biomass as precursor of condensing gaseous species. When using HMDS to remove the condensing gaseous species by growth machanism of particles, we could be controlled properly particles size such as amount of adsorbent injection, residence time, heating temperature and MFC flux. Especially, in case of using the silica precursor, in consideration of the physical and chemical properties of the boiling point, the specific gravity and the molecular weight, we found that the condensing species could be effectively controlled by particles granulation.
