  • Dissimilar metal-supported catalyst for the production of aromatics by methane dehydroaromatization and method for producing aromatics using the same
    Patent number: 11919832
    Abstract: Disclosed is a dissimilar metal-supported catalyst for the production of aromatics by methane dehydroaromatization. In the dissimilar metal-supported catalyst, a noble metal such as gold (Au), silver (Ag), platinum (Pt), and/or rhodium (Rh) is introduced into a catalyst supported with iron (Fe) on a zeolite support to promote the dehydrogenation of methane and the formation of iron carbide (Fe3C) as an active species for dehydroaromatization, achieving a greatly improved yield of aromatics. Also disclosed is a method for producing aromatics using the dissimilar metal-supported catalyst.
