Fischer â Tropsch synthesis has long been a well-recognized process for the conversion of syngas (H2 and CO) to commodity and fuel compounds such as methanol and long chain hydrocarbons. In this work, a series of Fischer - Tropsch Molybdenum-Sulfide catalysts have been prepared for the purpose of producing medium chain (C6 â C8) alcohols. Using a hydrothermal synthesis technique, alkali-promoted MoS2 catalysts were developed with the addition of cobalt. Catalysts were characterized using SEM, TEM, XRD, and BET to identify possible structural and chemical characteristics leading to their influence on activity and selectivity. Furthermore, the catalyst materials were evaluated for their formation of higher alcohol compounds. Reaction results indicated that cesium alkali and cobalt promoters were the most stable, active, and selective for the formation of medium chain alcohols. The Cs0.3Co0.5MoS2 catalyst (reacted at 3.2 MPa, 300 °C, and H2/CO = 0.8) favored C6 â C8 alcohols (93 wt % total mass of products). Complete details on catalyst synthesis, characterization, and reactions will be presented.
