The influence of the degree of back-mixing on hydrogen production in an anaerobic fixed-bed reactor
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
This paper reports on results obtained from experiments carried out in an acidogenic anaerobic reactor aiming at the optimization of hydrogen production by altering the degree of back-mixing. It was hypothesized that there ...
Prediction of the fixed-bed reactor behaviour using dispersion and plug-flow models with different kinetics for immobilised enzyme
(Elsevier Science Sa, 2003-05)
The behaviour of fixed-bed reactors, which have an immobilised enzyme on the packing surface, was studied considering steady-state conditions and external mass transfer resistance in the fluid around catalyst spherical ...
Photocatalytic Inactivation of Escherichia Coli Aqueous Suspensions in a Fixed-Bed Reactor
(Elsevier Science, 2014-09)
A fixed-bed, annular photoreactor is studied for the photocatalytic disinfection of Escherichia coli aqueous suspensions. Experiments were carried out under UV radiation employing P25 titanium dioxide immobilized onto glass ...
Simultaneous degradation of pharmaceuticals in fixed and fluidized bed reactors using iron-modified diatomite as heterogeneous Fenton catalyst
(2021)
The aim of this study was to evaluate the use of pelletized iron-modified diatomite as heterogeneous Fenton catalyst for the removal of carbamazepine, clindamycin, gemfibrozil, ketoprofen, florfenicol, and sulfamethazine, ...
Photocatalytic Reactor Modeling: Application to Advanced Oxidation Processes for Chemical Pollution Abatement
(Springer International Publishing, 2019-10)
A methodology for photocatalytic reactor modeling applied to advanced oxidation processes for chemical pollution abatement is presented herein. Three distinct reactor configurations typically employed in the field of air ...
Alternative Designs for Fixed Bed Catalytic Reactors
(Walter De Gruyter & CoBerlinAlemanha, 2004)
Predicting the packed-bed reactor performance with immobilized microbial lactase
(Elsevier, 2006-12)
A mathematical model for several working conditions was numerically solved to study a fixed bed reactor with a biocatalyst. The effect of bed swelling, mass transfer limitations, axial dispersion, residence times and inlet ...
Photocatalytic inactivation of bioaerosols in a fixed-bed reactor with TiO 2 -coated glass rings
(Royal Society of Chemistry, 2019-01)
The photocatalytic inactivation of Bacillus subtilis spores in air was evaluated employing a fixed-bed reactor with TiO 2 -coated glass rings, under artificial UV-A radiation. Calculations of the radiation effectively ...
An upflow fixed-bed anaerobic-aerobic reactor for removal of organic matter and nitrogen from L-lysine plant wastewater
(NATL RESEARCH COUNCIL CANADA-N R C RESEARCH PRESS, 2009)
This paper reports on the design of a new reactor configuration - an upflow fixed-bed combined anaerobic-aerobic reactor - can operate as a single treatment unit for the removal of nitrogen (approximate to 150 mg N/L) and ...
