Organobentonite as Efficient Textile Dye Sorbent
Authors: Jović‐Jovičić N. , Milutinović‐Nikolić A. , Gržetić I. , Jovanović D. 
Published: March 2008

AbstractDomestic bentonite clay was modified using cationic surfactant – hexadecyltrimethylammonium bromide (HDTMA‐bromide) in order to obtain more efficient sorbent. Removal of Acid Orange 10 from aqueous solution at different dye concentrations, adsorbent doses, and pH was studied. These studies were carried out under unaltered pH value in order to prove that adjusting pH as an additional operation in wastewater treatment is not entirely necessary. The results obtained confirmed the adsorption capacity is significant even for unaltered pH. The adsorption isotherm data were well fitted with both the Freundlich and Langmuir model and the latter was shown as more appropriate. Dynamical data were well represented with the pseudo second‐order kinetic model. The results indicate that HDTMA‐bentonite could be employed as low‐cost sorbent in textile dye wastewater treatment.
Removal of SO2 Using a Magnetically Fluidized Bed in the Semi‐Dry Flue Gas Desulfurization Process: Roles of Ferromagnetic Particles and Applied Magnetic Field in the Desulfurization Reaction
Authors: Zhang Q. , Gui K.‐T. 
Published: March 2008

AbstractA new semidry flue gas desulfurization (FGD) process is proposed. The process uses a magnetically fluidized bed (MFB) as the reactor in which ferromagnetic particles are fluidized with simulated flue gas under the influence of an external magnetic field. A slurry of lime is continuously sprayed into the reactor by an atomizer fixed at the top of the bed. As a consequence, the desulfurization reaction and slurry drying take place simultaneously in a same reactor. Experiments with a laboratory‐scale apparatus were carried out to investigate the roles of the ferromagnetic particles and the magnetic field applied in the desulfurization reaction. The results show that when ferromagnetic particles are used as the fluidization material, both sulfite (SO32–) salts and sulfate (SO42–) salts are found in the desulfurization products. When quartz particles are used, only sulfite (SO32–) salts are found. This suggests that the Fe(III) ions and Fe(II) ions result from the ferromagnetic particles dissolving in the liquid phase. In addition, the ions act as catalysts in the oxidation of S(IV) to S(VI) and react with SO2 producing FeSO3 and Fe2(SO4)3 as the products. On the other hand, the level of the sulfate (SO42–) salts in the products increases with increasing intensity of applied field intensity, which suggests that the oxidation of S(IV) can be enhanced by the applied magnetic field. The oxidation of S(IV) can increase the solubility of SO2, and therefore, intensify the reaction between SO2 and Ca(OH)2, leading to an increased SO2 removal efficiency.
The Removal of Copper with Dialkyldithiocarbamate Ligands in Condensed Carbon Dioxide

Published: March 2008

AbstractThe global kinetics of the oxidation and removal of copper(0) foil were examined in liquid and supercritical CO2 using tert‐butyl peracetate (t‐BuPA) as the oxidant and dialkyldithiocarbamate lithium salts (Li+R2DTC–, with R = ethyl, propyl, or n‐butyl) as the chelating agent. The pressure was kept constant (at 240 bar) for all reactions as density was not found to affect the kinetics at pressures above 150 bar. Temperature was varied between 25 and 60 °C and the concentrations of the oxidant and chelating agents were varied to determine the observed overall reaction orders for each species. Interestingly, under our reaction conditions, the observed global reaction was independent of oxidant concentration but varied due to the R2DTC– concentration. The Et2DTC– had an observed half order reaction dependence, indicating a complex reaction mechanism while the other two R2DTC– had first order dependence suggesting diffusion limitations. Arrhenius expressions were determined by the temperature dependent kinetics of the product, Cu(R2DTC)2, formation. The apparent activation energy, Ea, for the Et2DTC– was 66 kJ/mol, confirming a complex reaction mechanism due to its large value. The apparent activation energies for the Pr2DTC– and Bu2DTC– were 14 and 17 kJ/mol, respectively. These low energies are consistent with diffusion limitation.
Dynamic Optimization in Chemical Processes Using Region Reduction Strategy and Control Vector Parameterization with an Ant Colony Optimization Algorithm
Authors: Asgari S. A. , Pishvaie M. R. 
Published: March 2008

AbstractTwo different approaches of the dynamic optimization for chemical process control engineering applications are presented. The first approach is based on discretizing both the control region and the time interval. This method, known as the Region Reduction Strategy (RRS), employs the previous solution in its next iteration to obtain more accurate results. Moreover, the procedure will continue unless the control region becomes smaller than a prescribed value. The second approach is called Control Vector Parameterization (CVP) and appears to have a large number of advantages. In this approach, control action is generated in feedback form, i.e., a set of trial functions of the state variables are expanded by multiplying by some unknown coefficients. By utilizing an optimization method, these coefficients are calculated. The Ant Colony Optimization (ACO) algorithm is employed as an optimization method in both approaches.
Packing with Stamped Horizontal Lamellae Operating at Extremely Low Liquid Loads – III. Packing Pressure Drop
Authors: Kolev N. , Kralev B. , Razkazova‐Velkova E. 
Published: March 2008

AbstractIt has been discussed in previous papers [1–7] that the design of packings capable of operating at extremely low liquid superficial velocity allows the development of effective countercurrent flow packed bed columns even if the concentration of the absorbed component is very low, the absorption is an equilibrium process, and the gas is well soluble in the liquid phase. The construction of the new packing is described in [7]. The present paper reports the results of an investigation of the pressure drop for dry and irrigated packings up to a gas velocity equal to 3 m/s (FG factor equal to 3.3 kg1/2 m–1/2 s–1) as well as the equations for its calculation.
Investigation of the Precipitation of Barium Sulfate Nanoparticles
Authors: Petrova A. , Hintz W. , Tomas J. 
Published: March 2008

AbstractPrecipitation is a promising process for nanoparticle production because it is a fast, economic process and simple to design. In the present work, barium sulfate particles were produced by discontinuous precipitation in a stirred tank reactor. Particle sizes of less than 100 nm were achieved. Particle size distributions strongly depend on the mechanical mixing and the molar ratio of the reactants as well as on the stabilization of the particles in the suspension.
Preparation of a Transparent Spherical Polymer Matrix Containing TiO2/SiO2 Hybrid Materials
Authors: Zhang D.‐H. , Wu B.‐Y. 
Published: March 2008

AbstractA transparent spherical polymer matrix containing TiO2/SiO2 hybrid materials is prepared from the copolymerization reaction between TiO2/SiO2 hybrid materials containing vinyl groups and methyl methacrylate (MMA). Transparent TiO2/SiO2 hybrid materials are prepared from the reaction between nucleophilic agents and tetrabutyl titanate (TBT). Three reaction mechanisms leading to the formation of nanometer TiO2/SiO2 hybrid materials, including the single group coordination reaction mechanism (SGCRM), double group chelation reaction mechanism (DGCRM) and bridge coordination reaction mechanism (BCRM) are discussed in detail and confirmed by FT‐IR spectroscopy. The sizes of the TiO2/SiO2 hybrid material nanoparticles are also characterized and calculated by TEM and range from 20–40 nm. The diameter of the particles in the transparent spherical polymer matrix is ca. 100–200 nm and their shape is a regular spherical structure from TEM observations. The transparent spherical polymer matrix containing TiO2/SiO2 hybrid materials could be used as holographic anti‐counterfeiting materials.
