Kinetics and sintering mechanisms of hydro-thermally obtained hydroxyapatite
(Elsevier, 2008)
In this paper, the kinetics and sintering mechanism of hydro-thermally synthesized hydroxyapatite in the temperature range 900-1100 degrees C are presented. It was found that at 900 degrees C, the sintering process is very ...
The kinetics of the hydrogen evolution reaction on zinc in EDTA solutions in the pH 3-10 range
(Elsevier Science Sa, Lausanne, 2003)
Polarization curves of the hydrogen evolution reaction on zinc were obtained in Ethylenediaminetetraacetic acid (EDTA) solutions of different total molar concentrations (0.05, 0.10, 0.15 and 0.20 mol dm(-3)), the pH values ...
The Extraction of Copper from Chalcopyrite Concentrate with Hydrogen Peroxide in Sulfuric Acid Solution
(MDPI, 2023)
Research on chalcopyrite leaching represents a great challenge, given its importance as one of the most abundant copper minerals and its significant role in global copper extraction. This study aimed to evaluate the effects ...
Kinetic properties of the Ti-Ni intermetallic phases and alloys for hydrogen evolution
(Elsevier Science Sa, Lausanne, 1997)
The kinetics and mechanism of hydrogen evolution at Ti-Ni alloy electrodes prepared by are-melting and mechanical alloying methods has been studied by means of AC impedance spectrum measurements. The electrode, prepared ...
Experimental design approach regarding kinetics of high pressure leaching processes / Dizajniranje eksperimenata u pogledu na kinetiku luženja pri visokim pritiscima
(Savez inženjera metalurgije Srbije, Beograd, 2003)
Kinetics of high pressure leaching of nickel latente ore "Rudjinci", Serbia was studied in this work. The following parameters: temperature, acid to ore ratio, stirring speed, and time were optimized in order to obtain the ...
The thermal degradation of poly(diethyl fumarate) / Termička degradacija poli(dietil fumarata)
(Association of Chemical Engineers of Serbia, 2001)
The kinetics and mechanism of the thermal degradation of poly(diethyl tumarate) (PDEF) were studied by thermogravimetry and analysis of the polymer residue. The characteristic mass loss temperatures were determined, as ...
The kinetics of the thermal degradation of isomeric dipropyl and dibutyl esters of poly(itaconic acid)
(Pergamon-Elsevier Science Ltd, Oxford, 2000)
Non-oxidative and oxidative thermogravimetry was performed on poly(di-n-propyl-) (PDnPI), poly(di-iso-propyl-) (PDiPI), poly(di-n-butyl-) (PDnBI), poly(di-iso-butyl-) (PDiBI) and poly(di-sec-butyl itaconate) (PDsBI). The ...
Hydrogenation of oil produced by naphtha steam pyrolysis: Determination of catalyst activity / Hidrogenovanje pirolitičkog ulja nastalog u procesu pirolize primarnog benzina - određivanje aktivnosti katalizatora
(Association of Chemical Engineers of Serbia, 2000)
Residual pyrolysis oil (RPO) produced as a by-product of naphtha steam pyrolysis was hydrogenated (160-280°C; 60 bar; trickle-bed reactor with Co-Mo/y-AlgOs) with the aim of suppressing the polymerization of the unsaturated ...
Hydrodesulfurization of light gas oil: Kinetic determination in a batch reactor / Hidrodesulfurizacija lakog gasnog ulja
(Association of Chemical Engineers of Serbia, 2002)
The performed investigations were directed toward the analysis of the performance and activity of the fresh and regenerated Cyanamid HDS 20C catalyst in a laboratory batch reactor (2 dm3) for the HDS of the diesel fraction ...
Non-isothermal crystallization of k2o center dot tio2 center dot 3geo(2) glass
(Springer, Dordrecht, 2009)
The crystallization of K2O center dot TiO2 center dot 3GeO(2) glass under non-isothermal condition was studied. In powdered glass with particle sizes less than 0.15 mm, surface crystallization was dominant and an activation ...
