Abstract

In this study, experimental studies were performed for the carbon nanomaterial(CNM) which is catching on as a material for eco-ship. The opposed-flow methane flame was used as a heat source for synthesis of CNM. Ferrocene was used as a catalyst for the synthesis of CNM. These major parameters were $H_2$ mixing rate and sampling positions that synthesize CNMs in opposed-flow diffusion flames. The propensities of CNMs were experimentally determined using SEM and TEM images. The experimental result showed that the amount of CNTs was increased with increasing $H_2$ concentration. It can also be found that the optimal temperature in opposed-flow methane flame for synthesis of CNT was about 1500 K.

이 연구에서는 친환경 선박용 재료로 각광받는 탄소나노물질에 대하여 실험적 연구를 수행하였다. 탄소나노물질의 합성을 위한 열원으로서는 대향류 메탄 화염을 이용하였다. 탄소나노물질 합성을 위한 촉매로서는 페로센을 사용하였다. 합성 특성을 파악하기 위한 주요 파라메타로는 대향류 메탄 화염에 수소의 혼합 비율과 샘플링 위치를 변화시켰다. 탄소나노물질의 성향은 SEM과 TEM 이미지를 이용하여 결정되었다. 실험 결과로서는 수소의 혼합 비율이 증가할수록 탄소나노물질의 생성이 잘 이루어졌다. 또한 대향류 메탄 확산화염 내 탄소나노튜브의 생성을 위한 적정 온도로는 1500 K 정도가 적당하다는 것을 알 수 있었다.
