Modeling a Fluidized-Bed Reactor for the Catalytic Polymerization ff Ethylene: Particle Size Distribution Effects
(Planta Piloto de Ingeniería Química, 2005-12)
Particle size distributions in the output stream of commercial, fluidized-bed reactors for ethylene polymerization are analyzed using a mathematical model. The impact on the overall reactor performance of the universe of ...
Prediction of the combustion process in fluidized bed based on physical-chemical properties of biomass particles and their hydrodynamic behaviors
(Elsevier B.V., 2014-08-01)
The utilization of biomass in fluidized bed reactors is due to alternatives created by the carbon credit market and to environmental concerns. This fact calls for an accurate determination of physical-chemical properties ...
Anaerobic degradation of linear alkylbenzene sulfonate (LAS) in fluidized bed reactor by microbial consortia in different support materials
(ELSEVIER SCI LTD, 2010)
Four anaerobic fluidized bed reactors filled with activated carbon (R1), expanded clay (R2), glass beads (R3) and sand (R4) were tested for anaerobic degradation of LAS. All reactors were inoculated with sludge from a UASB ...
Photocatalytic oxidation of oxalic acid in dilute aqueous solution, in a fully illuminated fluidized bed reactor
(Pergamon-Elsevier Science Ltd, 2010-12)
A comprehensive kinetic model for the photooxidation of oxalic acid (C2O4H4) in a fluidized bed (FB) of a TiO2/quartz sand composite, in a UV-fully illuminated photoreactor, was developed and correlated with experimental ...
Real evidence about zeolite as microorganisms immobilizer in anaerobic fluidized bed reactors
(Elsevier, 2007)
Using the scanning electronic microscopy, it was observed that natural zeolite possesses excellent physical characteristics as a support medium
in anaerobic fluidized bed reactors (AFBR). Samples for biomass analysis were ...
Modeling of a fluidized-bed photocatalytic reactor for water pollution abatement
(Pergamon-Elsevier Science Ltd., 2001-12)
A system consisting of a fluidized bed of quartz-support particles impregnated with titanium dioxide in a UV-irradiated annular arrangement is presented as an efficient reactor configuration for the photocatalytic oxidation ...
Effect of Substrate Concentration on Dark Fermentation Hydrogen Production Using an Anaerobic Fluidized Bed Reactor
(HUMANA PRESS INCTOTOWA, 2012)
The effect of substrate (glucose) concentration on the stability and yield of a continuous fermentative process that produces hydrogen was studied. Four anaerobic fluidized bed reactors (AFBRs) were operated with a hydraulic ...
Experimental and theoretical investigation of anaerobic fluidized bed biofilm reactors
(Brazilian Society of Chemical Engineering, 2009-07)
This work presents an experimental and theoretical investigation of anaerobic fluidized bed reactors (AFBRs). The bioreactors are modeled as dynamic three-phase systems. Biochemical transformations are assumed to occur ...
Performance evaluation and phylogenetic characterization of anaerobic fluidized bed reactors using ground tire and pet as support materials for biohydrogen production
(ELSEVIER SCI LTD, 2011)
This study evaluated two different support materials (ground tire and polyethylene terephthalate [PET]) for biohydrogen production in an anaerobic fluidized bed reactor (AFBR) treating synthetic wastewater containing glucose ...
