Abstract

Biogas is a byproduct after anaerobic digestion of organic materials and has been used as an energy source for heating and generating electricity. Demands of methanol for fuel mixed with gasoline and reactant in biodiesel production are steadily being increased. In this review, we summarized recent advancements in direct partial oxidation of methane to methanol with the brief history of methanol synthesis. The steam reforming and the catalytic oxidation of methane to methanol were compared, the former of which are mainly used in industrial scale and the latter in a stage of research and development. On the basis of this review, the possibility of methanol conversion from biogas was proposed in the aspects of the technological feasibility and the economical practicability.

바이오가스는 유기물의 혐기소화과정에서 생기는 부산물로 열에너지와 전기에너지로 사용되어왔다. 바이오디젤생산의 반응물과 연료로 사용되고 있는 메탄올의 수요는 꾸준히 증가하고 있다. 본 총설에서는 메탄올을 메탄올로 전환하는 직접부분산화법의 최근 발전 동향을 간략한 메탄올합성의 역사와 함께 다루었으며, 산업 규모에서 주로 사용되고 있는 증기개질반응과 현재 연구단계에서 발전하고 있는 촉매산화법을 비교하였다. 이 총설에서는 바이오가스로부터 메탄올전환의 가능성이 기술적인 측면과 경제적 실용성 면에서 제시되었다.
