A CFD study on H2-permeable membrane reactor for methane CO2 reforming: Effect of catalyst bed volume

International journal of hydrogen energy, 2021
A 2D axisymmetric model is developed for a H2-permeable membrane reactor for methane CO2 reforming. The effect of catalyst bed volume on CH4 conversion and H2 permeation rate is investigated.

Influence of the order of the catalysts in the stacked bed of VGO hydrotreating catalysts

Fuel, 2021
Abstract The influence of the order of catalysts and their ratio in the bed for FCC feedstock hydrotreatment was investigated. CoMo/Al2O3 and NiMo/Al2O3 catalysts were prepared in the laboratory and studied by nitrogen adsorption–desorption, XPS and HRTEM methods. The catalysts were tested in hydrotreatment of model feedstocks. It was found that NiMo/

Catalyst bed dilution for improving catalyst wetting in laboratory trickle‐bed reactors

AIChE Journal, 1996
AbstractThe catalyst bed dilution technique has found rather widespread applications as a means of producing reliable and reproducible results for successful scale‐up and scale‐down when testing commercially used catalyst particle sizes and alternative feedstocks in small‐scale laboratory trickle‐bed reactors.

Laboratory Evaluation of Cracking Catalysts in a Fluid Bed:  Effects of Bed Dynamics and Catalyst Deactivation

Industrial & Engineering Chemistry Research, 2003
Testing of fluid cracking catalysts in laboratory microactivity units is carried out in either fixed- or fluid-bed reactors. The latter are becoming increasingly popular because of the automation they provide. This paper focuses on understanding the effects of testing protocols on product selectivities in such reactors and explains the cause of ...
