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 ...
Use of higher-order frequency response functions for identification of nonlinear adsorption kinetics: Single mechanisms under isothermal conditions
(Kluwer Academic Publ, Dordrecht, 2000)
The concept of higher-order frequency response functions (FRFs), which is based on Volterra series expansion of nonlinear functions, is used for analysis of kinetics of nonlinear adsorption systems. Four different kinetic ...
The possibilities of applying thermogravimetry in the characterisation of wood types / Mogućnosti primene termogravimetrije u karakterisanju drvnih vrsta
(Faculty of Technology, Novi Sad, 2000)
Thermogravimtery (TG) is a convenient method for the routine, as well as non-standard characterisation of polymeric materials. The changes in wood under various heating conditions were followed and on the basis of the ...
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 ...
Electrochemical characterization of LiCoO2 / Elektrohemijska karakterizacija LiCoO2
(Faculty of Technology, Novi Sad, 2000)
The electrochemical characteristics of LiCoO2 as a positive electrode for lithium-ion batteries, have been investigated. The LiCoO2 were sintetized from Li2CO3 and Co203 by thermal treatment at 1273 K for 24 h in the air. ...
Modulation of the mechanical properties of tissue engineered cartilage
(IOS Press, Amsterdam, 2000)
Cartilaginous constructs have been grown in vitro using chondrocytes, biodegradable polymer scaffolds, and tissue culture bioreactors. In the present work, we studied how the composition and mechanical properties of ...
ZnO varistors prepared by direct mixing of constituent phases
(Sendai : Japan Institute of Metals, 2000)
ZnO varistors with non-linearity coefficients reaching 50 and low values of the leakage current (approximately 0.01 A/m2), were obtained by a method referred to as `direct mixing of constituent phases'. The method is based ...
Surface chemistry of CO on Pt(100)-bimetallic surfaces: Displacement effects
(Amer Chemical Soc, Washington, 2000)
The surface chemistry of coadsorbed CO and metal adatoms on the Pt(100) surface in acid electrolyte has been studied by means of rotating ring disk electrode (RRDE) measurements. These results showed that Cu and Pb adatoms ...
The thermo-oxidative degradation of poly(2-chloroethyl methacrylate) in the presence of antioxidants / Termooksidativna degradacija poli(2-hloretil metakrilata) u prisustvu antioksidanata
(Association of Chemical Engineers of Serbia, 2000)
The oxidative thermal degradation of poly(2-chloroethyl methacrylate) (PCEMA) was studied in the presence of the following commercial antioxidants: CHIMASSORB 119 (CH 119) and CHIMASSORB 944 (CH 944), both based on amines, ...
Polymer optical fibers today / Polimerna optička vlakna danas
(Association of Chemical Engineers of Serbia, 2000)
Polymer optical fibers (so called POF) are already in wide use in a large number of fields. This paper gives an overview including a background of the development of polymer optical fibers, their advantages, various types ...
