Synthesis of fatty acid methyl esters from pomace oil catalyzed by zinc stearate: A kinetic study of the transesterification and esterification reactions
(Multidisciplinary Digital Publishing Institute, 2019-12)
In this work, the simultaneous transesterification and esterification reactions of olive pomace oil with methanol catalyzed by zinc stearate were studied. This catalyst is a crystalline solid at room temperature, but it ...
Kinetics and efficiency of ozone for treatment of landfill leachate including the effect of previous microbiological treatment
(Springer Heidelberg, 2019-02)
The application of conventional physicochemical and microbiological techniques for the removal of organic pollutants has limitations for its utilization on wastewaters as landfill leachates because of their high concentration ...
A Kinetic Study for the Fenton and Photo-Fenton Paracetamol Degradation in a Pilot Plant Reactor
(Elsevier, 2017-10)
The present study aims at proposing a kinetic model that can capture the complexity and non-linear nature of the Fenton and photo-Fenton processes in the degradation of a model pollutant. Moreover, the proposed model is ...
Kinetic study of Hubnerite (MnWO4) chlorination
(Elsevier Science, 2012-05-23)
The kinetics of Argentinean Hubnerite (MnWO 4) chlorination using gaseous chlorine as chlorination agent was studied between 750 and 950 °C. The relative mass change during the chlorination reaction was continuously monitored ...
Kinetic modeling of the liquid-phase hydrogenation of cinnamaldehyde on copper-based catalysts
(American Chemical Society, 2007-11)
The liquid-phase hydrogenation of cinnamaldehyde (CAL) on copper-based catalysts was studied using pseudo-homogeneous and heterogeneous Langmuir-Hinshelwood-Hougen-Watson (LHHW) kinetics. Three catalysts were used: Cu/SiO2, ...
Chemical kinetics in solar to chemical energy conversion: The photoelectrochemical oxygen transfer reaction
(Elsevier, 2019-02)
After introducing the basic aspects of the photoelectrochemical processes for the oxygen transfer reaction, we present the simplest kinetics models that have been built to represent the dynamics of light-induced redox ...
Kinetic model of water disinfection using peracetic acid including synergistic effects
(IWA Publishing, 2016-01)
The disinfection efficiencies of a commercial mixture of peracetic acid against Escherichia coli were studied in laboratory scale experiments. The joint and separate action of two disinfectant agents, hydrogen peroxide and ...
On line kinetic analysis of permeation profiles for UV filter loaded microemulsions using an automatic system with spectroscopic detection and a chemometric approach
(Royal Society of Chemistry, 2021-04-26)
The analysis of the permeation kinetics of new UV filter formulations is of great importance since the kinetic parameters are related to the effectiveness of the product over time. The dynamics of this process can be ...
Differential parameters between cytosolic 2-Cys peroxiredoxins, PRDX1 and PRDX2
(John Wiley & Sons Inc, 2019-01)
Peroxiredoxins are thiol-dependent peroxidases that function in peroxide detoxification and H2O2 induced signaling. Among the six isoforms expressed in humans, PRDX1 and PRDX2 share 97% sequence similarity, 77% sequence ...
Drying kinetics, microstructure, and texture of cheese cracker fillings
(Institution of Chemical Engineers, 2020-09)
The hot air drying process for cheese cracker fillings was assessed. Fillings with sheep-milk cheese and corn starch were prepared. Sodium alginate, carrageenan, locust bean, and xanthan gum were employed in order to obtain ...
