In order to provide for increasing global energy demand, alternative sources of energy need to be developed. Fischer Tropsch Synthesis is one such technology that can produce a wide variety of hydrocarbon products from gasified biomass feedstock. However, Fischer Tropsch Synthesis faces a several significant hurdles before it can be considered a reliable alternative source of liquid fuels. Mainly, the selectivity of Fischer Tropsch Synthesis to a narrow range of liquid hydrocarbons is difficult to achieve on a large scale, thus leading to expensive cracking and separation steps to purify the final product. As a result, catalysts with unique structures and chemical properties have been studied extensively to develop a catalyst with higher selectivity or conversion to a narrower range of hydrocarbon products. Due to the unique properties of graphene, including high surface area (>2600m2/g theoretical), high thermal conductivity (2000-4000W/m-K), and high electrical conductivity, it is hypothesized that a graphene support will facilitate heat transfer and electron mobility along the catalyst surface, thus improving the catalyst effectiveness in overall yield. As a result, graphene supported iron-oxide nanocatalyst was developed and tested to determine the graphene supportâ??s effect on liquid fuel production through Fischer Tropsch Synthesis.
