Numerical Study of Dry Reforming of Methane in Packed and Fluidized Beds: Effects of Key Operating Parameters

open access: yesChemEngineering, 2023
Replacing the conventionally used steam reforming of methane (SRM) with a process that has a smaller carbon footprint, such as dry reforming of methane (DRM), has been found to greatly improve the industry’s utilization of greenhouse gases (GHGs).

Compaction and dilation rate dependence of stresses in gas-fluidized beds

open access: yes, 2006
A particle dynamics-based hybrid model, consisting of monodisperse spherical solid particles and volume-averaged gas hydrodynamics, is used to study traveling planar waves (one-dimensional traveling waves) of voids formed in gas-fluidized beds of narrow ...

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Fluidization Quality of Fluidized Bed

open access: yesChemical engineering, 1957
This paper deals with the influence of the structure and shape of the vcssel and pipe line on the fluidization quality of fluidized bed as it is investigated by the author.The quality of fluidized bed was measured by means of non-uniformity index (fluidization index) proposed by W.W. Shuster. As the result, it was found out that the arrangements of the
