Abstract The potential silica nanospring (NS) supported cobalt catalyst (Co/SiO2-NS) for Fischer-Tropsch synthesis (FTS) was investigated, and the results were compared with those of a conventional silica gel supported cobalt catalyst (Co/SiO2-gel). Co/SiO2-gel and Co/SiO2-NS catalysts were prepared using the incipient wetness impregnation method and a thermal assisted reduction process, respectively, and characterized by scanning electron microscopy/ energy dispersive spectroscopy (SEM/EDS), transmission electron microscopy (TEM), N2 physisorption, X-ray powder diffraction (XRD), and H2-temperature programed reduction (H2-TPR). The catalysts were evaluated for their conversion of syngas to products in a quartz fix-bed micro-reactor (230 DGC, atm pressure). The FTS products were trapped and characterized by GC-MS to determine conversion efficiency. The products (alkanes) for both catalysts ranged from C1 to C21 and would be a suitable substrate for diesel. The results show that the NS approach for a FTS catalyst support shows promise for generating fuels from syngas. Future work will focus on optimizing Co/SiO2-NS catalyst for improved conversion efficiencies.
