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 ...
Investigation of dynamic young modulus during thermal stability testing of the refractory material / Određivanje dinamičkog jungovog modula elastičnosti tokom ispitivanja termostabilnosti vatrostalnog materijala
(Savez inženjera metalurgije Srbije, Beograd, 2002)
Thermal stability of the refractory material with the content of 42 % Al2O3 was investigated. Water quench test (JUS.B.D8.319.) was applied. Photographs of the samples before cycling, and after some number of cycles were ...
Glass-ceramic enamels derived from the Li2O-Na2O-Al2O3-TiO2-SiO2 system / Staklo-keramički emajli izvedeni iz sistema Li2O-Na2O-Al2O3-TiO2-SiO2
(Serbian Chemical Society, Belgrade, 2002)
The results of research on the conditions for obtaining model glass-ceramic enamels, derived from the basic Li2O-Na2O-Al2O3-TiO2-SiO2 system, by varying the initial composition and thermal treatment conditions, are presented ...
Shot-peening induced twinning in ship-building steel / Dvojnikovanje u brodskom limu kao posledica tretiranja u mlazu sačme
(Savez inženjera metalurgije Srbije, Beograd, 2002)
The aim of this work to simulate a shot-peening process and reveal the final microstructure. The latter consisted of rafinated ferritic grains, with occurrence of twins in some grains. Since the twinning occurs when a very ...
Influence of heat transfer conditions on determination of thermal shock resistance of refractories / Uticaj prenosa toplote na određivanje termostabilnosti vatrostalnog materijala
(Savez inženjera metalurgije Srbije, Beograd, 2002)
The goal of this thesis was to determine the thermal shock resistance of alumina based refractories in the case of a heat transfer conditions different from the standard conditions given by quenching test JUS. B. D.8 319. ...
