Abstract：In view of the gas-soild separation at the top of Fischer-Tropsch reactors, the flow field simulation of cyclone separator was discussed and the gas-solid flow characteristics was checked. The results showed that the solid phase particles were enriched on the wall of the cyclone separator under centrifugal force. Under the pressure, the gas was moved towards the center of the separator and discharged from the ascending pipe. The solid particles were collided with the wall of cyclone separator and moved in a broken line which had poor following property with gas. The axial velocity of the gas was greater than zero at the outer edge of cyclone separator roof, straight cylinder section and cone section junction, which resulted a long residence time and enriched. In addition, the separation efficiency of cyclone separator was related to the size of particles. The simulation results showed that the separation efficiency could reach 99.9% when particle size was above 10 μm, which could meet the separation requirements.
