| 英文摘要 | Five different internals were designed, and their effects on phase holdup and backmixing were investigated in a gas–liquid concurrent upflow reactor where the spherical alumina packing particles of three diameters (3.0, 4.5 and 6.0?mm) were slightly expanded under the conditions of varied superficial gas velocities (6.77?×?10 ?2 - 3.61?×?10 ?1 ?m·s ?1 ) and superficial liquid velocities (9.47?×?10 ?4 - 2.17?×?10 ?3 ?m·s ?1 ). The experimental results show that the gas holdup increases with the superficial gas velocity and particle size, opposite to the variational trend of liquid holdup. When an internal component is installed amid the upflow reactor, a higher gas holdup, a less liquid holdup and a larger Peclet number characterizing the weaker backmixing are obtained compared to those in the bed without internals under the same operating conditions. Additionally, the minimal backmixing is observed in the reactor equipped with the internals with a novel multi-step design. Finally, empirical correlations were proposed for estimating gas holdup, liquid holdup and Peclet number with the relative deviations within 11%, 12% and 25%, respectively. |
