Mass and momentum transfer in packed beds of spherical inert particles
(Serbian Chemical Society, Belgrade, 1996)
Mass transfer coefficients between fluid and immersed sphere in liquid dense and loose packed beds of spherical inert particles have been studied experimentally using column 40 mm in diameter. Mass transfer data were ...
The interfacial stability of magnetically stabilized fluidized beds
(Serbian Chemical Society, Belgrade, 1996)
The study concerns a phenomenon in which the magnetization of ferromagnetic particles stabilizes the state of uniform fluidization in gas-solid, liquid-solid and gas-liquid-solid fluidized beds. Fluidization regimes and ...
Sorption of boric acid and borax by activated carbon impregnated with various compounds
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
The separation of boron compounds, boric acid and borax from aqueous solution by activated carbon before and after impregnation with various compounds was studied. A series of activated carbons was prepared from coconut ...
Boron removal by anion exchangers impregnated with citric and tartaric acids
(Taylor & Francis Inc, Philadelphia, 1996)
The separation of boron compounds, boric acid and borax, with anion-exchange resins, before and after impregnation with citric and tartaric acids, has been studied. Three different commercially available anion exchangers ...
Nondispersive solvent extraction-stripping of phenol in a hollow fiber-in-fiber membrane contactor
(Serbian Chemical Society, Belgrade, 1996)
Phenol extraction from aqueous solution and its simultaneous concentration into caustic stripping solution using a hollow fiber-in-fiber type membrane contactor was investigated. The phenol separation rate using sunflower ...
Apparent energy of activation for hot working of vanadium microalloyed steel
(Serbian Chemical Society, Belgrade, 1996)
Two-stage linear In [sinh(ασca)] vs.1/T plots, based on isothermal continuous and anisothermal multipass torsion curves, indicate the double Q HW behaviour of a V-steel. Above T nr , Q HW is independent of all variables ...
A rheological study of behavior of polymer-bitumen blends
(Erdoel Erdgas Kohle/EKEP, 1996)
The influence of the elastomer such as SBS and SBR and their mixtures on the structure and rheological properties of blown bitumen B 65 blends, was studied. The crude oil denoted as SEB (Soviet Export Blend) was used to ...
Synthesis, morphology, and formation mechanism of mullite particles produced by ultrasonic spray pyrolysis
(Cambridge Univ Press, New York, 1996)
Submicrometer spherical particles of mullite powder were synthesized by ultrasonic spray pyrolysis of emulsion and solutions, using tetra-ethyl-orthosilicate (TEOS) or silicic-acid and Al(NO3)(3) . 9H(2)O as initial ...
Synthesis and characterization of a new chiral polyurea-based catalyst
(John Wiley & Sons Inc, New York, 1996)
A series of chiral poly(urea)s was synthesized by solution polyaddition. The polymers are characterized by NMR, FTIR, DSC, viscosimetry, and microanalysis. After deposition of the rhodium, the insoluble chiral polymers ...
The sorption characteristics of epoxy coatings electrodeposited on steel during exposure to different corrosive agents
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
Organic protective coatings on steel were formed by cathodic electrodeposition of an epoxy resin modified by an amine and isocyanate using a constant voltage method (resin concentration 10% wt, temperature 26 degrees C, ...
