Conventional and emerging processes that require the application of multiphase reactors
are reviewed with an emphasis on catalytic processes. In the past, catalyst discovery and …

Trickle-bed reactors (TBRs) are extensively used in industry. There have been great
progresses in design and control of the TBRs. However, more improvements are required in …

Studies on micro-packed beds were reviewed pointing out major contributions with their key
findings. Negligible mass transfer resistance and temperature gradients in micro-packed …

The state-of-the-art of the gas-liquid mass transfer characteristics in trickle-bed reactors was
summarized and its quantification methods were reevaluated based on a wide-ranging data …

This paper presents the results of a study carried out to examine liquid hold-up and flow
distribution in a 0.1 m internal diameter column filled with catalytic structured packing …

Bubble size distributions in a two-dimensional packed bed are investigated as a function of
axial direction by using image processing techniques with a large number of bubble …

Gas–liquid concurrent downward flow through a new structured packing was investigated by
experiment systematically. The experimental packing consisted of 21 sieve plates. Each …

In order to predict the pressure drop and the mean void fraction for bubbly flows in packed
beds, a new one‐dimensional (1‐D) model is proposed. The balance equations for both …

A simple hydrodynamic model for cocurrent gas–liquid bubbly flow through a packed-bed
reactor is developed. The model involves the momentum balance equations for the …

The mechanisms of bubble motion in concurrent gas–liquid down flow through trickle beds
are investigated. The laboratory reactor is a structured quasi-two-dimensional porous …
