A packed-bed basket containing corn cob powder was used for the adaptation of a concentric-tube airlift reactor for enzymatic reactions. The bed was inserted in the downcomer region of the bioreactor generating a decrease ...

Because shape is an assessment of the three-dimensional form of a particle, it may be described in terms of sphericity (Psi), which is a measure of how closely a particle approaches a spherical configuration. In this study, ...

The permeability of material is a relevant characteristic of porous media that can be applied on several science and engineering fields. Polymers are chemical compounds of high molecular weight and those which are water ...

The drying process of particulate biological materials in fixed bed is influenced by several factors associated with the particles and the bed packing. The main objective of this research was to evaluate the drying of ...

Convective drying of leaves involves heat and mass transfer in packed-beds of deformable material, since the leaves shrink significantly when the moisture is removed. Therefore, the packing structure changes over time, and ...

In this work were determined the main physicochemical properties of seeds of millet (Setaria italica) and their dependence on the moisture content. The drying of seeds under different conditions was also evaluated in order ...

Baffle mitigation structures can be built from permeable obstacles with non-fixed bases, leaving the question of how easy it is for these structures to slide. In this master thesis, we study the stability of permeable ...

One of the main steps in the manufacture of robust and efficient packed capillary microcolumns for electro- and capillary chromatography is the generation of porous devices to retain the packed beds. Frits based on sintered ...

The hardening furnace of raw pellets from Samarco SA, type the traveling grate also called Straight Grate, is used in the firing iron ore pellets inserted into the grate cars moving with a certain speed through heating ...
