摘　　要：在装有金属烧结丝网作为过滤介质的内部过滤元件的浆态鼓泡反应器中,考察了颗粒粒径40—70μm和60—90μm、固相质量分数0—30%、气体流速2—6cm/s、操作温度25—150℃、过滤压降0.1—0.3MPa和反冲洗压差0.4—1.0MPa等操作因素对过滤速率的影响。实验结果表明过滤速率随着颗粒粒径、温度的提高及固相质量分数的降低而增大,并对不同过滤方式进行了考察。In the slurry bubble column reactor of Fischer-Tropsch synthesis equipped with the internal filtering element made of sintered metal wire-mesh as filtering medium, effects of operating temperature 60—150 ℃, pressure drop 0.1—0.3 MPa, particle diameter 40—70 μm, 60—90 μm, solid mass fraction 0—30%, superficial gas velocity 2—6 cm/s and gas back-flushing pressure differential 0.4—1.0 MPa on filtering rate of the filter element were investigated. The experimental results show that filtering rate increases with the increase of particle diameter,temperature and the decrease of solid mass fraction. The mode of filtration on filtering rate was examined.
