Abstract: A serious of Magnesia-carbon nanotubes (abbreviated as MgO-CNTs) nanocomposites with different weight ratio were prepared by impregnation of CNTs and used for Fischer–Tropsch synthesis. The results indicated that most of the MgO-CNTs supported catalysts showed high CO conversion and the olefin selectivity was higher than the others when the MgO/CNTs ratio was 2:1 under 2 MPa at 350 oC. The catalysts were characterized by scanning electron microscope (SEM), temperature programmed reduction (TPR) of H2, X-ray diffraction (XRD) and N2 desorption.
Key words: Fischer–Tropsch synthesis; CO conversion; MgO-CNTs
