Based on theoretical analysis and experimental results, a new attempt has b
een made to characterize the dynamics of the fluid flowing under conditions
of pulsing flow in a trickle-bed reactor (TBR). Two kinds of correlation a
re proposed for the dynamic liquid holdup under pulsing flow, which can pre
dict the dynamic liquid holdup for a given packing type and given operating
conditions. (C) 2000 Elsevier Science S.A. All rights reserved.
