As shown in Figure 1,there are liquid phase and solid phase in the reactor,because they are mixed so well that they could be considered as one slurry phase.The gas phase goes into the riser in the form of bubbles through a distributor and then most of them could remain in the gas/slurry separator.There are nearly no bubbles existing in the downcomer,so the slurry could circulate in the reactor because of density difference between the riser and the downcomer.When the slurry enters the downcomer,the liquid/solid mixture could be separated in the filter by transmembrane pressure.The permeate would return to the reactor and the condensed slurry could return to the riser.The permeate flux was measured by the gravimetric method and the cumulative mass distribution of solid particles was measured by a laser particle size analyzer(Mastersizer)as shown in Figure 2.Air,water and FCC equilibrium catalysts represent the gas phase,the liquid phase,and the solid phase,respectively.Materials properties are listed in Table 1.
