A review of the available information about the packed bed reactors with cocurrent upflow of
gas and liquid (UFRs), particularly focused on heat transfer with an external medium through …

Phenol hydrogenation is an environmentally friendly route to produce cyclohexanone, an
important intermediate for manufacturing nylon-6 and nylon-66. Herein, a gas–liquid …

Phenol is present as a highly toxic pollutant in wastewater, and it has a dangerous impact on
the environment. In the present research, the phenol removal from wastewater has been …

The controlling of residence time and gas–liquid interface distribution is critical issue in
operating packed bed reactors with gas–liquid concurrent upflow. Herein, gas–liquid …

A HiGee-aided fixed bed reactor (HFBR) has great potential for catalytic hydrogenation with
hydrogen microbubble swarm for gas–liquid mass transfer intensification. However, the flow …

Packing size effects on the fluid dynamics in an external‐loop packed bubble column with
Raschig rings of three different effective diameters (4.9, 14.1, and 40.7 mm) in the riser were …

Gas‐liquid flows through packed bed reactors (PBRs) are challenging to predict due to the
tortuous flow paths that fluid interfaces must traverse. Experiments at the International Space …

Significance: Gas–liquid up‐flow in a packed bed is studied experimentally in the limit of
zero flow rate. Two patterns of bubble behavior are detected based on the magnitude of the …

The work is devoted to the review and analysis of gas-lift and bubble equipment designs. In
particular, the paper presents the study, generalization, and critical appraisal of scientific …

The hydrodynamics of gas and liquid flow through a granular bed were proposed in this
work. By introducing optical principles, a high-speed camera was used to capture bubbles at …
