Abstract

This study is experimentally investigated brown gas generative properties with the changes of cell areas, a electrolyte concentration and ampere current for the developments of small brown gas generation equipments usable in diesel cars. Electrolysis reactors have been manufactured as SMT30, SMT50, SMT50-1, SMT70, SMT90, respectively on various surface areas and different positions anode and cathode. Thus, the brown gas generative properties on reactors tended to increase as surface area increase, and show differences in different electrode positions. However, the effect on electrolyte concentration had increased with a decreasing electrolyte concentration of NAOH 3~1‰, and the brown gas generative properties on ampere of SMT30, SMT50, SMT50-1, SMT70, SMT90 have shown to be $0.74{\ell}/10min$, $1.0{\ell}/10min$, $1.10,{\ell}/10min$, $0.97{\ell}/10min$, $1.13{\ell}/10min$.

디젤자동차용 소형브라운가스 생성 장치의 개발을 위하여 전극 셀의 재료로서 SuS와 Ni 및 Ag기반 셀을 제조하고 셀의 면적과 전해질의 농도 및 전류의 세기를 변화시켜 브라운가스 생성특성을 실험적으로 분석하였다. 전기분해 반응기는 셀의 표면적 및 전극 -극과 +극 배치를 다르게 하여 SMT30, SMT50, SMT50-1, SMT70, SMT90로 제조하였다. 이 때 각 반응기의 따른 브라운가스 생성특성은 셀의 접촉 면적이 클수록 생성특성이 증가하는 경향을 보였으며 전극배치의 경우는 같은 전극면적에서도 극의 배치 따라 차이가 있는 것을 보였다. 또한 전해질의 농도에 대한 영향은 NaOH를 1~3‰로 변화시켰을 때 농도가 적을수록 생성특성이 증가하였고, 전류의 세기의 따른 생성특성은 SMT30, SMT50, SMT50-1, SMT70, SMT90에서 각각 $0.74{\ell}/10min$, $1.0{\ell}/10min$, $1.10{\ell}/10min$, $0.97{\ell}/10min$, $1.13{\ell}/10min$가 얻어졌다.
