## NMR spectroscopy. Structural characterization by elemental analysis, FTIR, and NMR spectroscopy on both vacuum-distilled and air-blown pitches showed that distillation of lighter fractions, reduction of atomic H/C ratio, and dehydrogenation raised their softening points. Structural analysis by N
The dynamic behaviour of the continuous phase in liquid solid fluidized bed is characterized through velocity measurements by laser anemometry at the top of the bed. The experiments were conducted using glass particles of 2, 4 and 8 mm diameter fluidized by water. The root mean square (RMS) of axial
