Analysis of catalyst effectiveness in trickle-bed reactors processing volatile or nonvolatile reactants
TLDR
In this paper, the problem of evaluating catalyst effectiveness for a slab, cylindrical, or spherical shape results in a general dual-series equation which for a given geometry may be reduced to a variety of cases of interest by proper assignment of Biot numbers for dry and wetted surfaces.About:

Comparison of trickle-bed and upflow reactor performance at high pressure: Model predictions and experimental observations
TL;DR: In this article, a comparison of laboratory trickle-bed and up-flow reactors over a range of operating conditions, which cover both gas and liquid reactant limitations, has been investigated using hydrogenation of alpha-methylstyrene to cumene in a hexane solvent over 2.5% Pd on alumina extrudate catalyst as a test reaction.

A trickle-bed reactor model for hydrogenation of 2,4 dinitrotoluene: experimental verification
TL;DR: In this article, a trickle-bed reactor model has been developed for hydrogenation of 2,4 dinitrotoluene (DNT), which incorporates the contributions of partial wetting and stagnant liquid hold-up effects in addition to external and intraparticle mass transfer resistances for a complex consecutive/parallel reaction scheme represented by L-H-type kinetics.

Liquid-induced pulsing flow in trickle-bed reactors
TL;DR: In this article, the authors describe the experiments on pulse induction by cycling the liquid feed in a column of 3.2 m height and two feed strategies are developed that involve the artificial induction of natural pulses and a separation of the wetting efficiency in time.

Comparison of Upflow and Downflow Two-Phase Flow Packed-Bed Reactors with and without Fines: Experimental Observations
TL;DR: In this article, the performance of laboratory trickle-bed and upflow reactors over a range of operating conditions was compared using the hydrogenation of α-methylstyrene to cumene in hexane solvent.

Trickle-bed reactors: Liquid diffusional effects in a gas-limited reaction
TL;DR: In this paper, a model was developed for predicting the performance of a partially wetted trickle-bed reactor for a gas-limiting reaction of order less than or equal to one.

Partial wetting in trickle bed reactors — the reduction of crotonaldehyde over a palladium catalyst
W. Sedriks,C.N. Kenney +1 more
TL;DR: In this paper, the behavior of a trickle bed in which the catalytic packing was incompletely wetted was investigated using the selective hydrogenation of crotonaldehyde to n -butyraldehyde as a model reaction.
