Apparatus for manufacturing molten iron and method for manufacturing syngas using the same

The present invention relates to an apparatus for manufacturing molten iron, capable of manufacturing synthetic gas by using exhaust gas generated during operation, and a synthetic gas manufacturing method using the same. According to the present invention, the method comprises: a process of charging iron ore in a reduction furnace and supplying reduction gas to manufacture reduced iron; a process of charging at least a part of the reduced iron in a reaction furnace; a process of supplying exhaust gas generated in a process to manufacture the reduced iron and methane-containing gas to the reaction furnace; and a process of using the reduced iron as a catalyst to react the exhaust gas with the methane-containing gas to manufacture a synthetic gas containing carbon monoxide and hydrogen. The reduced iron manufactured in a melting reduction steelmaking process is charged in the reaction furnace, and the exhaust gas generated in the process to manufacture the reduced iron and the methane-containing gas, which is modified gas, are charged in the reaction furnace, thereby being able to manufacture the synthetic gas. 본 발명은 용선 제조 장치 및 이를 이용한 합성가스 제조방법에 관한 것으로, 환원로에 철광석을 장입하고 환원가스를 공급하여 환원철을 제조하는 과정; 반응로에 상기 환원철 중 적어도 일부를 장입하는 과정; 상기 반응로에 상기 환원철을 제조하는 과정에서 발생하는 배가스와 메탄 함유 가스를 공급하는 과정; 상기 환원철을 촉매로 이용하여 상기 배가스와 메탄 함유 가스를 반응시켜 일산화탄소와 수소를 함유하는 합성가스를 제조하는 과정;을 포함하고, 용융 환원 제철공정에서 생산되는 환원철을 반응로에 장입하고, 반응로에 환원철을 제조하는 과정에서 발생하는 배가스와 개질가스인 메탄함유 가스를 반응시켜 합성가스를 제조할 수 있다.
