Use of stirred batch reactors for the assessment of adsorption constants in porous solid catalysts with simultaneous diffusion and reaction. Theoretical analysis
(Pergamon-Elsevier Science Ltd, 2006-03)
A simple, pseudo-equilibrium model was derived for a catalytic system with a first order chemical reaction and simultaneous diffusive and adsorptive processes, in order to assess the corresponding kinetics and Henry ...
Mass Transfer Limitations in Slurry Photocatalytic Reactors: Experimental Validation
(Elsevier, 2010-04)
In the present work the existente of mass transfer limitations in slurry, photocatalytic reactors is studied. Experimental validation is made in a flat plate reactor that is part of a recycling system. The reactor is ...
Simultaneous Biodegradation and Detoxification of the Herbicides 2,4-Dichlorophenoxyacetic Acid and 4-Chloro-2-Methylphenoxyacetic Acid in a Continuous Biofilm Reactor
(Springer, 2017-07)
The herbicides 2,4-diclorophenoxiacetic and 4-chloro-2-methylphenoxyacetic acids (2,4-D and MCPA) are widely used in agricultural practices worldwide. Not only are these practices responsible of surface waters contamination, ...
DECOLORACIÓN SONOQUÍMICA SINÉRGICA DEL ANARANJADO DE METILO UTILIZANDO TRICLOROMETANO EN DOS REACTORES ULTRASÓNICOS
(Universidad Nacional Autónoma de México. Centro Ciencias de la Atmósfera, 2020-01)
The discoloration of methyl orange (AM), an azo dyer with mutagenic properties, is studied. The action of trichloromethane (HCCl3) (TM) is analyzed as a synergistic agent, using batch and continuous ultrasonic reactors. ...
Production of protein nanovehicles by heat treatment of industrial egg white in a batch reactor
(Elsevier, 2020-03)
A process to obtain protein nanovehicles to carry lipophilic bioactive compounds (LBC) was developed by heat treatment of industrial liquid egg white (EW) in a batch reactor (1.0 L). It was noted an increase in particle ...
Solketal synthesis from ketalization of glycerol with acetone: A kinetic study over a sulfated zirconia catalyst
(Elsevier Science, 2021-07-15)
In this work, a series of acid catalysts were synthetized from a commercial zirconium oxide sulfated with a 0.5 M H2SO4 solution by wet impregnation. The characterization results show a correlation between the calcination ...
Strategies for oxidation of PAHs in aged contaminated soil by batch reactors
(Academic Press Inc Elsevier Science, 2018-04)
Polycyclic aromatic hydrocarbons (PAH) are neutral, nonpolar and hydrophobic molecules that tend to sorb onto soil organic matter. Chemical oxidation is a good choice to avoid the limitations of bioremediation. To evaluate ...
Modeling a Silicon CVD Spouted Bed Pilot Plant Reactor
(Berkeley Electronic Press, 2006-01-17)
This study reports a comprehensive multiphase gas-solid dynamic mathematical model that successfully describes the batch growth of silicon particles in a CVD submerged spouted bed reactor. This multiphase reactor model ...
Biodiesel production using supercritical alcohols with a non-edible vegetable oil in a batch reactor
(Elsevier Science, 2010-07)
In the present work, the transesterification of non-edible oil with methanol and ethanol is studied. The reactor phase transitions are directly observed in a double windowed cylindrical reactor and the conversion to fatty ...
Continuous production of cyclodextrins in an ultrafiltration membrane reactor, catalyzed by Cyclodextrin glycosyltransferase from Bacillus circulans DF 9R
(American Chemical Society, 2015-01)
Cyclodextrins (CDs) are cyclic oligosaccharides of wide industrial application, whose synthesis is catalyzed by Cyclodextrin glycosyltransferase (CGTase) from starch. Here, CDs were produced using CGTase from Bacillus ...
