Zusammenfassung:	The present invention relates to a dissimilar metal-supported catalyst for preparing aromatic compounds by dehydroaromatization of methane and a method for preparing aromatic compounds using the same. The dissimilar metal-supported catalyst according to the present invention additionally introduces noble metals such as gold (Au), silver (Ag), platinum (Pt), and rhodium (Rh) to a catalyst in which iron (Fe) is supported on a zeolite carrier to accelerate formation of iron carbide (Fe_3C), which is an active species in dehydrogenation reaction and dehydroaromatization reaction, thereby improving production yield of aromatic compounds. 본 발명은 메탄의 탈수소방향족화 반응에 의한 방향족 화합물 제조용 이종금속 담지 촉매 및 이를 이용한 방향족 화합물의 제조방법에 관한 것이다. 본 발명에 따른 이종금속 담지 촉매는 제올라이트 담지체에 철(Fe)이 담지된 촉매에 금(Au), 은(Ag), 백금(Pt) 및 로듐(Rh) 등의 귀금속을 추가 도입함으로써 탈수소화 반응 및 탈수소방향족화 반응의 활성종인 탄화 철(Fe3C)의 형성을 촉진함으로써 방향족 화합물의 생산 수율을 크게 향상시킬 수 있다.
