A preliminary process for developing a natural gas autothermal reforming (ATR) reactor for fuel cells is presented in this paper. A experimental reactor for methane ATR was constructed and used for characterization of ATR reactor. Temperature profiles of the reactor were observed, and reformed gas compositions were analyzed to evaluate efficiency, conversion and reaction heat with varying amounts of O2/CH4 at selected furnace temperature and H2O/CH4. The amount of O2/CH4 showed strong effects on reactor temperature, efficiency and conversion indicating that O2/CH4 is a crucial operation condition. Operation conditions which result in thermal neutrality of ATR reactor system were determined for two cases of an ATR system based on the estimation of enthalpy difference between reactants of assumed inlet temperatures and the products from experimental results. The determined conditions for thermally neutral operations could be used for guidelines to design reformers and for determining the operation parameters of a self-sustaining ATR reactor. 대한기계학회 연료전지용 천연가스 자열개질기의 기초특성연구 Study on Basic Characteristics of Natural Gas Autothermal Reformer for Fuel Cell Applications Article 2 대한기계학회논문집 B, v.30, no.9, pp.850 - 857 대한기계학회논문집 B 30 9 850 857 kci ART001094554 Key Words : Autothermal Reforming(자열개질) Fuel Cell(연료전지) Natural Gas(천연가스)
