| 中文摘要 | The fluidization characteristics of anthraquinone hydrogenation catalysts were investigated in a liquid-solid fluidized bed. The effects of the initial bed conditions such as particle size, bed depth-to-column diameter ratio and liquid density and viscosity on the fluidization behaviour, bed expansion and applicability of the Richardson - Zaki equation were studied. The results reveal a strong particle size effect on the Richardson - Zaki (R-Z) expansion index which in general decreased as the particle diameter increased. One type of particles exhibited two distinct bed expansion behaviours, depending mainly on the bed depth-to-column diameter ratio, with an experimentally established boundary at h(b0)/D approximate to 1.75. This behaviour could be attributed to increasing wall friction and a tendency to exhibit slugging. The dependence of the Richardson - Zaki exponent on the liquid dynamic viscosity confirms the classic result n(a) = f(1/Re(t)). |
