Comparative 2D and 3D analysis on the hydrodynamics behaviour during biomass gasification in a pilot-scale fluidized bed reactor
(2019-02-01)
2D and 3D simulations were carried out to predict the whole gasification process behaviour in a pilot-scale bubbling fluidized bed reactor. Special concern for the complex hydrodynamics phenomena within the fluidized bed ...
Fluidization of forest biomass-sand mixtures: experimental evaluation of minimum fluidization velocity and CFD modeling
(Taylor & Francis, 2020-07-03)
An experimental fluid-dynamic study of sand-forest biomass mixture fluidization was conducted. Different proportions of biomass/sand were tested. Sawdust from the Abra Ancha sawmill, located in the town of Aluminé, Argentina, ...
Análise fluidodinâmica da variação da razão de aspecto de partículas cilíndricas em leito fluidizado
(Universidade do Vale do Rio dos Sinos, 2018-10-26)
The environmental impact caused by the combustion of mineral coal in thermal plants stimulates researches for sustainable alternatives. One of the alternatives may be the replacement of coal by biomass in fluidized bed ...

Three-phase model of a fluidized-bed catalytic reactor for polyethylene synthesis
(De Gruyter, 2016-01)
A mathematical model of a bubbling fluidizedbed reactor for the production of polyolefins is presented. The model is employed to simulate a typical, commercialscale reactor where the synthesis of polyethylene using supported ...
Solar and artificial UV inactivation of bacterial microbes by Ca-alginate immobilized TiO2 assisted by H2O2 using fluidized bed photoreactors
(SCIENCE & TECHNOLOGY NETWORK INC, 2014-07-01)
In this work, TiO2 (Degussa, P-25) supported on calcium alginate pearls was evaluated as catalyst for the photocatalytic inhibition of pathogenic microorganisms. Considering that water samples were taken directly from a ...
Electrocoagulation/flotation followed by fluidized bed anaerobic reactor applied to tannery effluent treatment
(Desalination Publ, 2012-01-01)
A series operation of electrocoagulation/flotation (ECF) and fluidized bed anaerobic reactor (FBR) was conducted to treat tannery wastewater. Although both reactors were operated in fill-and-draw (batch) mode, effluent ...
