Summary: | [Display omitted]
•Co and Co/Ru-based catalysts with 5%wt. Co, 10%wt. Co and 0.4%wt. Ru supported on SiO2 for the Fischer-Tropsch process have been synthesized by Flame Spray Pyrolysis (FSP).•5wt% of Co sample did not show any activity toward the FT synthesis while 10%wt of Co and 10%wt of Co − 0.4%wt of Ru samples are suitable catalysts for GTL process.•10%wt sample showed a great stability in function of TOS at T=250°C in terms of reactants conversion and products selectivity.•Products selectivity to CO2, CH4, light hydrocarbons (<C7) and heavy hydrocarbons (>C7) remains essentially unchanged at different temperatures.
Flame spray pyrolysis (FSP) is an innovative and scalable technique, used to synthesize monometallic and bimetallic Co-Ru catalysts with 5%wt. Co, 10%wt. Co and 0.4%wt. Ru supported on SiO2 active in the Gas-to-Liquids (GTL)-Fischer-Tropsch (FT) process, which converts syngas to hydrocarbons. The catalysts were characterized by TEM, FE-SEM-EDX, TPR, XRD and N2 adsorption/desorption. All the three samples have been tested in a fixed bed FT-bench scale plant. Results demonstrated that the 5%wt. Co catalyst was not active toward FT synthesis, while samples containing 10% wt. Co and 10% wt. Co - 0.4% wt. Ru were suitable candidates for the GTL-FT process. With an increase in temperature, the CO conversion increased, the product selectivity remained unchanged, and the 10%wt. Co catalyst showed higher stability as a function of time-on-stream (TOS) with respect to traditionally prepared materials. The addition of 0.4%wt. of Ru improved the performance in terms of CO conversion and C2+ yield. |
