Kinetics and Modeling of Fatty Alcohol Ethoxylation in an Industrial Spray Loop Reactor
The kinetics of the ethoxylation of fatty alcohols catalyzed by potassium hydroxide was studied to obtain the rate constants for modeling of the industrial process. Experimental data obtained in a lab-scale semibatch ...
Cure kinetics of diglycidylether of bisphenol A– ethylenediamine revisited using a mechanistic model
(John Wiley & Sons Inc, 2001-09-14)
The polymerization kinetics of the reaction between diglycidylether of bisphenol A (DGEBA) and ethylenediamine (EDA) was analyzed, using dynamic scanning calorimetry, in both isothermal and programmed heating-rate modes. ...
Model-free kinetics applied to sugarcane bagasse combustion
(Elsevier Science BvAmsterdamHolanda, 2006)
Non-isothermal kinetic of oxidation of tungsten carbide
Tungsten carbide, WC, has shown dissimilar thermal behavior when it is heated on changeable heating rate and flow of oxidant atmosphere. The oxidation of WC to WO3 tends to be in a single and slow kinetic step on slow ...
Classical Antiferromagnetism in Kinetically Frustrated Electronic Models
(American Physical Society, 2014-05)
We study, by means of the density matrix renormalization group, the infinite U Hubbard model—with one hole doped away from half filling—in triangular and square lattices with frustrated hoppings, which invalidate Nagaoka’s ...
Comparison of Empirical and Kinetic Modeling of the Photocatalytic Oxidation of Cyanide
(De Gruyter, 2007-12)
An intrinsic kinetic model based on the reaction mechanism of the photocatalytic oxidation of cyanide with TiO2 has been developed and applied to the results of experiments carried out using different catalyst concentrations, ...
Kinetic Modelling of the Photocatalytic Inactivation of Bacteria
(Iwa Publishing, 2010-03)
This work analyzes the kinetic modelling of the photocatalytic inactivation of E. coli in water using different types of kinetic models; from an empirical equation to an intrinsic kinetic model including explicit radiation ...
On the cure kinetics modeling of epoxy-anhydride systems used in glass reinforced pipe production
(Elsevier Science, 2013-10-08)
Aiming to determine a suitable model to describe the curing kinetics of a commercial epoxy/anhydride initiated by a quaternary amine system used for the production of glass reinforced pipes, calorimetric and infrared ...
Modeling the sorption kinetic of metsulfuron-methyl on Andisols and Ultisols volcanic ash-derived soils: Kinetics parameters and solute transport mechanisms
Metsulfuron-methyl sorption kinetic was studied in Andisol and Ultisol soils in view of their distinctive physical and chemical properties: acidic pH and variable surface charge. Different kinetic models were applied to ...
Crystallization kinetic of fluoro-zirconate glasses by non-isothermal analysis
(Kluwer Academic Publ, 2003-01-01)
Fluoride glasses have been extensively studied due to their high transparency in the infrared wavelength. The crystallization kinetics of these systems has been studied using DTA and DSC techniques. Most of the experimental ...
