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 reaction was investigated using a fixed-bed microreactor. Cobalt and Manganese bimetallic catalysts on carbon nanotubes (CNT) support (Co-Mn/CNT) were synthesized via the strong electrostatic adsorpt...
