Abstract

In this study, plasma reformer technology with a LPG injector was investigated. It was developed with injection of LPG fuel and air in a region where the plasma discharge to make the thermal decomposition carbon fuel and to generate additional hydrogen. As a result of reforming test, when power is 70~100W supply, about HC 0.7% of the full reformed gas and hydrogen was generated from 1.2 to 1.5 %.

본 연구에서는 LPG자동차용 LPG 액상분사 인젝터의 분사구 앞에 장착할 수 있는 플라즈마 개질기의 개발을 진행하였다. 이 개질기는 플라즈마 방전이 발생하는 영역에 공기와 LPG 연료를 분사시켜 고분자 탄소연료를 열해리시키고 추가로 수소를 발생시키기 위한 목적으로 개발되었다. 인젝터와 플라즈마 발생부와의 거리와 기하학적인 방전길을 최적화하여 개질 반응이 일어나는 인젝터 개질기를 완성하였으며, 개질 결과 공급 전력 70~100W 일 때 HC은 전체 개질가스의 약 0.7% 이며, 수소는 1.2~1.5% 발생하였다.
