Study of the iron(III)-modified clinoptilolite in the adsorption of phosphate from aqueous medium: mechanism and kinetics
(Desalination Publ, Hopkinton, 2017)
Clinoptilolite-rich tuff (Z) enriched with Fe(III) was studied in the removal of phosphate ions present in aqueous medium at pH = 6.5. Fe(III) modification was performed by a simple wet impregnation giving the product (FeZ) ...
Synthesis of Aliphatic Esters of Cinnamic Acid as Potential Lipophilic Antioxidants Catalyzed by Lipase B from Candida antarctica
(Springer, New York, 2013)
Immobilized lipase from Candida antarctica (Novozyme 435) was tested for the synthesis of various phenolic acid esters (ethyl and n-butyl cinnamate, ethyl p-coumarate and n-butyl p-methoxycinnamate). The second-order kinetic ...
Kinetics of Heterogeneous Biodiesel Synthesis Using Supported ZnO as Catalyst
(Wiley-VCH Verlag Gmbh, Weinheim, 2014)
A heterogeneous catalyst, ZnO supported on alumina/silica, was synthesized by the sol-gel method. The prepared catalysts were employed for methanolysis of sunflower oil. Effects of various supports as well as calcination ...
Kinetics and reactor modeling for CaO sorption-enhanced high-temperature water-gas shift (SE-WGS) reaction for hydrogen production
(Elsevier Sci Ltd, Oxford, 2016)
Hydrogen, an important energy carrier of the future, produces no pollution and has a high content of energy. It is formed as a direct product of the water-gas shift (WGS) reaction, which occurs in various processes for the ...
Influence of common juniper berries pretreatment on the essential oil yield, chemical composition and extraction kinetics of classical and microwave assisted hydrodistillation
(Elsevier Science Bv, Amsterdam, 2018)
The present paper dealt with the influence of the common juniper berries pretreatment on the yield, chemical composition and extraction kinetics of juniper essential oil (JEO) obtained by classical (HD) and microwave ...
Kinetic Modeling of Sunflower Oil Methanolysis Catalyzed by Calcium-Based Catalysts
(Wiley-VCH Verlag, 2015)
The kinetic model originally developed for quicklime-catalyzed methanolysis of sunflower oil was tested for another three calcium-based catalysts, namely, neat CaO, Ca(OH)2, and CaO·ZnO. This model includes the changing ...
Kinetics and mechanism of degradation of Co(II)-N-benzyloxycarbonylglycinato complex
(Springer, Dordrecht, 2012)
The kinetics of multi-step thermal degradation of Co(II) complex with N-benzyloxycarbonyl glycinato ligand [Co(N-Boc-gly)(2)(H2O)(4)]center dot 2H(2)O, in non-isothermal conditions was studied using isoconversional and ...
A new kinetic model for the common juniper essenstial oil extraction by microwave hydrodistillation
(Chemical Industry Press, Beijing, 2019)
The main objective of the present study was to model the kinetics of essential oil extraction from swelled ground juniper berries by classic hydrodistillation (HD) and microwave-assisted hydrodistillation (MAHD). A new ...
Modeling the kinetics of calcium hydroxide catalyzed methanolysis of sunflower oil
(Elsevier, 2010)
The kinetics of Ca(OH)2-catalyzed methanolysis of sunflower oil was studied at a moderate temperature (60 °C), a methanol-to-oil molar ratio (6:1) and different catalyst amounts (from 1% to 10% based on oil weight). The ...
Kinetics of the oxygen evolution reaction on NiSn electrodes in alkaline solutions
(Elsevier Science Sa, Lausanne, 2015)
In order to examine the intrinsic catalytic activity and durability of the electrodeposited NiSn alloy electrodes and the electrodeposited Ni as a reference electrode material for the oxygen evolution reaction (OER) in ...
