    Carbon-Supported KCoMoS2 for Alcohol Synthesis from Synthesis Gas
    (Multidisciplinary Digital Publishing Institute, 2021-10-30) Osman, Mohamed E; Maximov, Vladimir V; Dorokhov, Viktor S; Mukhin, Viktor M; Sheshko, Tatiana F; Kooyman, Patricia J; Kogan, Viktor M
    KCoMoS2 was supported on various carbon support materials to study the support effect on synthesis gas conversion. Next to two activated carbons with high micropore volume, a traditional alumina (γ-Al2O3) support and its carbon coated form (CCA) were studied for comparison. Coating alumina with carbon increases the selectivity to alcohols, but the AC-supported catalysts show even higher alcohol selectivities and yields, especially at higher temperatures where the conversions over the AC-supported catalysts increase more than those over the γ-Al2O3-based catalysts. Increasing acidity leads to decreased CO conversion yield of alcohols. The two activated-carbon-supported catalysts give the highest yield of ethanol at the highest conversion studied, which seems to be due to increased KCoMoS2 stacking and possibly to the presence of micropores and low amount of mesopores.
