Estimation of the radial distribution of axial velocities in fixed beds of spherical packing
(Institution of Chemical Engineers, 2019-07-24)
The vessel wall of densely packed beds exert a strong influence on particle distribution that generates a radial porosity profile and, in turn, a radial profile of axial velocity. A direct consequence is the appearance of ...
Prediction of breakthrough curves in packed-bed column as tool for lysozyme isolation using a green bed
(Springer, 2019-11)
The adsorption of lysozyme onto alginate–guar gum bed cross-linked with epichlorohydrin has been studied in packed-bed column. Adsorption performance was evaluated with different bed heights, flow rates and initial protein ...
Removal of ammonium via simultaneous nitrification-denitrification nitrite-shortcut in a single packed-bed batch reactor
(ELSEVIER SCI LTD, 2009)
A polyurethane packed-bed-biofilm sequential batch reactor was fed with synthetic substrate simulating the composition of UASB reactor effluents. Two distinct ammonia nitrogen concentrations (125 and 250 mg l(-1)) were ...
Experimental and numerical investigation of dynamic heat transfer parameters in packed bed
(SPRINGER, 2010)
Dynamic experiments in a nonadiabatic packed bed were carried out to evaluate the response to disturbances in wall temperature and inlet airflow rate and temperature. A two-dimensional, pseudo-homogeneous, axially dispersed ...
Modeling for Taxol (R) Separation in a Simulated Moving Bed
(Inst Tecnologia ParanaCuritiba-paranaBrasil, 2010)
The effect of biomass immobilization support material and bed porosity on hydrogen production in an upflow anaerobic packed-bed bioreactor
(2013)
The aim of this study was to investigate the effect of the support material used for biomass attachment and bed porosity on the potential generation of hydrogen gas in an anaerobic bioreactor treating low-strength wastewater. ...
Heat transfer in fixed bed: a model non-linearity approach
(Elsevier B.V., 2000-06-01)
Studies have been carried out on the heat transfer in a packed bed of glass beads percolated by air at moderate flow rates. Rigorous statistic analysis of the experimental data was carried out and the traditional two ...
