The search for alternative energy sources that can replace oil is gaining prominence in the world energy scenary. In this regard, recent studies show that synthetic liquid fuels derived from syngas present themselves as potential candidates for partially or totally replace conventional fuels derived from petroleum. Furthermore, important environmental aspects may be contemplated when the synthesis gas is obtained from non-fossil methane, resulting from the anaerobic fermentation of biomass contained in domestic and industrial waste in the form of biogas. The transformation process of the synthesis gas to liquid compounds is called GTL (Gas to Liquid) and is carried out at moderate temperatures, high pressures and in the presence of a catalyst. It is proposed the study of two different catalytic systems characterized by nanometric dimensions, which will be evaluated by the Fischer-Tropsch process. The first system will consist of CoFe/ZrO2 catalysts with core-shell morphology. The second system will be composed by CoPt/FAU catalysts prepared from ion exchange in nanocrystalline faujasite zeolite. The choice of catalytic systems was performed by searching in literature sources which point the potential of these materials in reactions similar to the proposed one. Studies comprove that nanocrystalline solids have relevant features that improve its performance in several catalytic reactions. Furthermore, bimetallic type core-shell catalysts have great flexibility in the improvement of various catalytic properties when compared to monometallic catalysts. From the above, it is clear that the physico-chemical characteristics as well as the metal-support interactions, the particle size and reaction conditions are the main points to be approached for better understanding and improvement of the Fischer-Tropsch process and with this, we have the projection of a job with scientific, technological and environmental relevancies.
