| Abstract: | The principal areas being looked at currently are using the fluidized bed for large particles and thermo-gravimetric analyzer (TA) for soot reactions. The fluidized bed will be used to work on the large particles. Early on, it was decided that only one particle would be examined, that it should be removable at any point in the reaction, and that a continuous CO[sub 2] analyzer be used to give better resolution in the bed. The soot particles needed to test the TA are being examined and modified to meet our needs. Since we wish to examine the evolution of the distance between graphite planes as the soot reacts, we felt that slight graphitization needed to take place in order to give good X-ray diffraction results. The corresponding TEM pictures of the soots at for the base soot and after 1500[degrees]C graphitization are shown in Figures 1 and 2. As can be seen, there as a fairly substantial amount of graphitization by 1500[degrees]C, as expected from Busek's work. |
