Abstract

Considerable attention has been given to developing methodologies to reduce the emission of carbon dioxide from industry to meet strengthened environmental regulations. In this article, recent research trends on dry reforming of methane as an alternative method to reduce $CO_2$ emission from large scale industrial processes are addressed. To efficiently provide the energy needed in this strong endothermic reaction without additional $CO_2$ emission, it seems to be desirable to adopt autothermal reaction mode. The produced synthesis gas could be used as a reducing gas, or a feedstock for synthesis of chemicals and fuels.

온실가스 배출 규제에 따라 이산화탄소 배출 감축은 산업계에서 해결해야 할 가장 중요한 과제 중 하나가 되었다. 이산화탄소는 온실가스 발생원 중 대부분을 차지하며 본 논문에서는 실제 대규모 산업 현장에서의 이산화탄소 배출을 저감하는 직접적인 방안으로 메탄의 이산화탄소 개질 반응을 이용하는 방법을 고찰해 보았다. 강한 흡열 반응 형태인 이 반응에 대해 추가적인 이산화탄소 발생을 피하며 효율적으로 에너지를 공급하기 위해서는 자열 개질 반응을 이용하는 것이 적합한 방법으로 판단된다. 생산된 합성가스는 환원가스로 재활용하거나 화학제품 및 연료의 합성에 활용할 수 있다.
