초록

본 총설에서는 최근 청정수소생산방법으로 큰 관심을 받고 있는 에탄올 수증기개질반응(ethanol steam reforming reaction)에 대해 소개하고자 한다. 다양한 촉매, 반응온도, 에탄올과 물의 몰비에 따른 에탄올 수증기개질반응의 반응특성 및 반응속도식(reaction rate equation)을 검토해 보고자 한다. 또한, 반응기와 분리기를 동시에 장착한 새로운 개념의 막반응기(membrane reactor)를 소개하며, 막반응기의 사용이 일반적인 충전층반응기(packed-bed reactor)에 비해 에탄올 전환율과 수소 수율에 어떠한 영향을 주는지에 대하여 고찰해 보고자 한다.

Ethanol steam reforming reaction considered as a clean hydrogen production method is introduced in this paper. Reactivity and reaction rate equation of ethanol steam reforming reaction using various catalysts, reaction temperature, and molar ratio of ethanol and water will be discussed. In addition to introducing a membrane reactor combining a reactor and a separator, the effect of the use of a membrane reactor on an ethanol conversion and hydrogen yield will be compared to those from a conventional packed-bed reactor.
