Effect of Temperature, Syngas Space Velocity and Catalyst Stability of Co-Mn/CNT Bimetallic Catalyst on Fischer Tropsch Synthesis Performance

The effect of reaction temperature, syngas space velocity, and catalyst stability on Fischer-Tropsch was investigated using a fixed-bed microreactor. Cobalt Manganese bimetallic catalysts carbon nanotubes (CNT) support (Co-Mn/CNT) were synthesized via the strong electrostatic adsorption (SEA) method. For testing performance catalyst, Co-Mn/CNT with four different manganese percentages (0, 5, 10, 15, 20%) synthesized. Synthesized then analyzed by TEM, FESEM, atomic absorption spectrometry (AAS), zeta potential sizer. In this study, temperature varied from 200 to 280 °C velocity 0.5 4.5 L/g.h. Results showed an increasing pressure 20 atm, Space 2.5 L/h.g H2/CO ratio 2, lead rise CO % conversion 59.5% 88.2% increase for C5+ selectivity 83.2% 85.8%. When compared other formulation, sample 95% cobalt 5% CNT (95Co5Mn/CNT) performed more stable 48 h stream.
