Biosorption and desorption of lanthanum(III) and neodymium(III) in fixed-bed columns with Sargassum sp.: Perspectives for separation of rare earth metals
(Wiley-Blackwell, 2012-05-01)
Rare earth (RE) metals are essentials for the manufacturing of high-technology products. The separation of RE is complex and expensive; biosorption is an alternative to conventional processes. This work focuses on the ...
Modeling of syngas composition obtained from fixed bed gasifiers using Kuhn–Tucker multipliers
(2021-03-01)
This work consists of developing a predictive model (PM) for syngas composition obtained from biomass gasification in fixed bed gasifiers. The PM is composed of three correlations which are made for carbon conversion ...
Fluid dynamics of air in a packed bed: velocity profiles and the continuum model assumption
(Brazilian Society of Chemical Engineering, 1999-12-01)
Air flow through packed beds was analyzed experimentally under conditions ranging from those that reinforce the effect of the wall on the void fraction to those that minimize it. The packing was spherical particles, with ...

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 ...
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, ...
Prediction of the copper (II) ions dynamic removal from a medium by using mathematical models with analytical solution
