Catalytic incineration of ethylene oxide in the packed bed reactor
(Elsevier, 2006)
Investigations of catalytic incineration of ethylene oxide (ETO) over Pt/Al2O3 catalyst have been conducted on laboratory and pilot scale level. The measurements of the reaction rate conducted under gradientless conditions ...
Carbon cryogel as support of platinum nano-sized electrocatalyst for the hydrogen oxidation reaction
(Electrochimica Acta, 2006)
The kinetics of hydrogen oxidation reaction was studied in perchloric acid solution on carbon-supported Pt nanoparticles using the rotating disk electrode technique. Carbon cryogel and commercial carbon black. Vulcan XC-72 ...
High activity of Pt4Mo alloy for the electrochemical oxidation of formic acid
(Amer Chemical Soc, Washington, 2007)
Surface processes on Pt4Mo alloy well-defined by X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) were studied in acid solution by cyclic voltammetry. It was established that Mo in the alloy is much more ...
Manganese leaching in the FeS2-MnO2-O2-H2O system at high temperature in an autoclave
(Elsevier Science Publishers B.V., 2000)
The paper shows: (a) the results of pyrite oxidation by gaseous oxygen in water suspension at high temperatures in an autoclave and (b) the results of simultaneous leaching of Mn4+ from pyrolusite ore by H2SO4 and FeSO4, ...
Prediction of the choking velocity and voidage in vertical pneumatic conveying of coarse particles
(Elsevier, 2006)
A method for predicting the choking velocity and voidage in vertical pneumatic conveying of coarse particles is developed and verified using the data obtained in this study as well as the data of Capes and Nakamura [C.E. ...
Influence of ionic equilibrium in the CuSO(4)-H(2)SO(4)-H(2)O system on the formation of irregular electrodeposits of copper
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
The relative concentration of hydrogen ion (H(+)) as a function of sulfuric acid (H(2)SO(4)) concentration (calculated using Pitzer's model) and the electrochemical processes by which irregular copper deposits are formed ...
Mechanochemical synthesis of nanocrystalline titanium monoxide
(Elsevier, 2008)
Nanocrystalline cubic titanium monoxide, TiOx (0.92 < x < 1.19), with mean crystallite size of ≈ 6 nm, was synthesized by mechanochemical treatment of Ti and TiO2 (rutile) powder mixtures with molar ratios of 1:1, ...
Modeling of the substrate and product transfer coefficients for ethanol fermentation
(WILEY-VCH Verlag GmbH & Co., 2008)
The transfer phenomena of the substrate and product for ethanol fermentation with immobilized biocatalyst were investigated. Fermentation was carried out with a biocatalyst consisting of Ca-alginate gel in the form of ...
Comparative study of cu(2+) adsorption on a zeolite, a clay and a diatomite from Serbia
(Applied Clay Science, 2009)
The adsorption of a zeolite, clay and diatomite from Serbia toward aqueous Cu2+ ions was studied, at different pH. The adsorbents were characterized with respect to phase composition, specific surface area and point of ...
Chitosan contribution on wool treatments with enzyme
(Elsevier Ltd., 2008)
In a previous research work, it was observed that the application of biopolymer chitosan (CHT) on wool fabrics before the enzymatic treatment promotes an increase of the weight loss. In order to deep on the role played by ...
