Optimization Approach for Continuous Catalytic Regenerative Reformer Processes
(Amer Chemical Soc, Washington, 2010)
The new approach for simulation and optimization of a continuous catalytic regenerative (CCR) reformer process is proposed. Typical CCR reforming processes consist of three to four reactors with recycle. The reaction ...
Thermomechanical Properties and Cavitation Resistance of a High-Alumina Low-Cement Castable
(Wiley-Blackwell, Malden, 2011)
The purpose of this study was to investigate the mechanical properties and level of cavitation damage to alumina-based low-cement castable. The effects of temperature treatment on some of the mechanical properties (strength, ...
Durability of sulfur concrete in various aggressive environments
(Elsevier Sci Ltd, Oxford, 2011)
Durability of sulfur concrete with different fillers, as well as Portland cement concrete, was tested in the solutions of HCl, H(2)SO(4), and NaCl. Regarding mass changes, in the solutions of HCl and H(2)SO(4) sulfur ...
Synthesis and characterization of silver/poly(N-vinyl-2-pyrrolidone) hydrogel nanocomposite obtained by in situ radiolytic method
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
This work describes radiolytic synthesis of silver nanoparticles (Ag NPs) within the poly(N-vinyl-2-pyrrolidone) (PVP) hydrogel. The hydrogel matrix was obtained by gamma irradiation-induced cross-linking, while the in ...
Surface Characterization of Iron-Modified Sepiolite by Inverse Gas Chromatography
(Amer Chemical Soc, Washington, 2011)
Inverse gas chromatography at infinite and finite surface coverages was applied to evaluate the surface properties of an iron-modified sepiolite sorbent, Fe-sepiolite. The adsorptions of different nonpolar and polar probes ...
Carboxylic acids and polyethylene glycol assisted synthesis of nanocrystalline nickel ferrites
(Elsevier Sci Ltd, Oxford, 2013)
Different synthesis methods for the preparation of nanocrystalline nickel ferrites are reported: the thermal decomposition of precursors, made of: (i) metal-nitrate salts with carboxylic acids (citric, malonic and tartaric), ...
Strain hardening of austenite in Fe-Cr-C-V alloys under repeated impact
(Elsevier Science Sa, Lausanne, 2011)
Structural changes were analyzed in Fe-Cr-C-V alloy balls with high chromium and different vanadium content, after repeated impact load testing. The results indicate that plastic deformation and strain hardening occur in ...
Bioflavour production from orange peel hydrolysate using immobilized Saccharomyces cerevisiae
(Springer, New York, 2013)
The rising trend of bioflavour synthesis by microorganisms is hindered by the high manufacturing costs, partially attributed to the cost of the starting material. To overcome this limitation, in the present study, dilute-acid ...
Adsorption of chromium (VI) from aqueous solutions onto amine-functionalized natural and acid-activated sepiolites
(Elsevier Science Bv, Amsterdam, 2013)
Chromium(VI) adsorption onto amine-functionalized sepiolites from aqueous solution at 298 K was investigated. Natural and add-activated sepiolites were functionalized by covalent grafting [3-(2-aminoethylamino)propyl] ...
The Viscoelastic Properties of Modified Thermoplastic Impregnated Multiaxial Aramid Fabrics
(Wiley, Hoboken, 2012)
This study reports the manufacture of new fabric forms from the preparation of hybrid laminated multiaxial composites with enhanced thermo-mechanical properties. Thermal and dynamic mechanical analysis of polymer matrix ...
