“…However, some controversy persists because one school thought asserts that both magnetite and metallic Fe are active for FTS, while the carbides are inactive. Yet another school of thought advances that WGS reaction occurs on magnetite sites, while FTS takes place on the carbide sites [41]. Other authors claim that the non-stoichiometric Fe-oxidecarbide complex is the active phase [42].…”

A short review of our results is presented on the use of high temperature plasma technology in producing catalysts for application in Fischer-Tropsch synthesis (FTS). Nanometric carbon-supported catalysts based primarily on Co and Fe with various metal formulations were synthesized using an induction suspension plasma-spray (SPS) system. The active catalytic species of the metals and the C-matrix support composing both graphitic (G) and amorphous (D; disordered) carbon were all simultaneously generated in situ within the plasma. The Co/C catalyst was the most active when tested for FTS with high selectivity towards the longer hydrocarbon chains. At 220 °C, 2MPa pressure; gas hourly specific velocity of over 3,600cm 3 .h -1 .g -1 of catalyst, it indicated ~40% CO conversion with the following selectivity expressed as % in the products: 30% gasoline (C 5 -C 12 ), 45% diesel (C 13 -C 20 ), and 21% waxes (C 21+ ), with less than 4% CH 4 and trace amounts of CO 2 . Other catalysts tested include Fe/C, bimetallic Co-Fe/C formulations and those promoted with Ni, Mo, and Au-Ni. It has been shown that particle size influences FTS when using plasma-synthesized catalysts: thus, particles in the mean size range of 9-11nm were more selective towards the diesel fraction and waxes, while larger particles of mean size of 14-21nm produced more gasoline. Since SPS technology is a relatively new approach in catalyst synthesis, being a one-step process potentially offers an overall higher efficiency and new prospects for the commercial production of synthetic fuels through FTS.
