Conversion of Poly(Ethylene Terephthalate) Waste into Activated Carbon: Chemical Activation and Characterization
Authors: Adibfar Mohammad , Kaghazchi Tahereh , Asasian Neda , Soleimani Mansooreh 
Published: May 2014

AbstractDue to its high carbon content, low impurities, low cost and easy availability, poly(ethylene terephthalate) (PET) waste is considered as a suitable precursor for the production of activated carbon. The chemical activation of PET wastes using different chemical agents such as H3PO4, H2SO4, ZnCl2, and KOH was investigated. KOH‐ and ZnCl2‐activated PET were found to be the best choices for the adsorption of small and large molecules. The capacities of the adsorbents towards I2, methylene blue, N2, CH4, and CO2 followed the order KOH‐PET >H3PO4‐PET > ZnCl2‐PET > H2SO4‐PET; however, in the molasses uptake and selective adsorption of CO2 compared to CH4, ZnCl2‐PET performed better than the other adsorbents.
Determination and Comparison of Equilibrium Data of Various Plant‐Based Fatty Acid Mixtures
Authors: Dasgupta Sunanda , Ay Peter , Schulz Stephanie 
Published: May 2014

AbstractMultistage melt crystallization of a variety of plant‐based polyunsaturated fatty acid (PUFA) mixtures was conducted to obtain an overview on their liquid‐solid equilibrium behavior. Crystal fraction and mother liquor samples were analyzed at every stage. Phase behavior diagrams at low saturated fatty acid concentrations were investigated in detail as they are of significant technical relevance with respect to efficient depletion of the saturated content from the samples. A high oleic acid content in the PUFA mixtures led to difficulties in depleting the mother liquor from the saturated content by melt crystallization. Thermograms from the differential scanning calorimetry were supplemented with illustrations which allow a novel interpretation of results and verification of conclusions.
Combined Production of Biodiesel and Nontoxic Cottonseed Meal Using Two‐Step Two‐Phase Solvent Extraction
Authors: Cao Jing‐Jing , Wang Fei , Fan Hui , Yun Zhi 
Published: May 2014

AbstractThe preparation of biodiesel and nontoxic cottonseed meal from cottonseed by two‐step two‐phase solvent extraction (TS‐TSE) combined with the transesterification reaction was investigated. The TS‐TSE process could significantly reduce the biodiesel production costs when compared with the two‐phase solvent extraction (TSE) process due to the reduction in methanol. A series of experiments was conducted to evaluate the effects of some factors on the fatty acid methyl ester (FAME) yield and free gossypol (FG) content. These conditions resulted in a maximum FAME yield and reduced the FG content in the cottonseed meal far below the Food and Drug Administration standard. The nontoxic cottonseed meal could be used as animal feed protein source.
Simulating Supercritical Water Jets with a Variable Turbulent Prandtl Number
Authors: Schuler Martin J. , Rothenfluh Tobias , Stathopoulos Panagiotis , Brkic Dragana , Meier Thierry , Rudolf von Rohr Philipp 
Published: May 2014

AbstractSupercritical water jets are of interest for the hydrothermal spallation drilling technology to thermally fragment rock. The important thermal field of such jets was investigated via axial temperature measurements inside a high‐pressure vessel simulating the harsh pressure and temperature conditions found downhole. Deionized water was electrically preheated to supercritical temperatures and afterwards discharged into a slowly co‐flowing cooling water ring. Furthermore, a numerical model was developed and applied. Difficulties in simulating the thermal field due to the strongly varying fluid properties around the pseudo‐critical point of water were highlighted and critically discussed. An approach of a locally varying turbulent Prandtl number is introduced to improve the predictions compared to the experiment. Finally, all numerical results were validated with experimental data.
Simultaneous Adsorption of SO2, NO, and CO2 by K2CO3‐Modified γ‐Alumina
Authors: Yi Honghong , Huang Bin , Tang Xiaolong , Li Kai , Yuan Qin , Lai Ruiyun , Wang Pan 
Published: May 2014

AbstractThe simultaneous adsorption of SO2, NO, and CO2 on K2CO3‐modified γ‐alumina under different operating conditions was studied in a fixed‐bed reactor. The experimental results showed that the influence of a temperature increase on the simultaneous adsorption of the three gases was complex and different from the effects seen when both chemical adsorption and competitive adsorption existed. An increase in O2 concentration and small amounts of water could enhance the adsorption of SO2 and NO while the adsorption of CO2 was not influenced. The breakthrough curves of the simultaneous adsorption experiments suggested that the investigated adsorbent may be a good candidate for the simultaneous adsorption of SO2, NO, and part of the CO2 while the adsorption capacity for CO2 still needs to be enhanced.
Mathematical Modeling and Methodic Scale‐up for Efficient Filter Apparatus Development
Authors: Gruschwitz Florian , Nirschl Hermann , Anlauf Harald 
Published: May 2014

AbstractIn many filtration applications, process parameters vary considerably due to differing boundary conditions. To develop a new filter apparatus, consequently the whole bandwidth of possible scenarios has to be considered for a fully functional real‐scale design. In order to reduce experimental efforts, analytical and numerical methods can be useful. For dimensioning of a new design apparatus for lube oil filtration in large diesel engines, a methodic approach could be developed with a mathematical model for the characteristics of the clogging process. With this method, all possible operative settings can be easily simulated and the experimental effort is considerably reduced.
Energy Evaluation of Ethanol Dehydration with Glycol Mixture as Entrainer
Authors: Benyahia Khadidja , Benyounes Hassiba , Shen Weifeng 
Published: May 2014

AbstractExtractive distillation of ethanol dehydration using glycols as entrainers is proposed. Specifically, ethanol dehydration of an azeotropic mixture in the presence of ethylene glycol + glycerol mixture is evaluated. Simulation is performed and the vapor‐liquid equilibrium of ethanol + water + ethylene glycol + glycerol is predicted with the NRTL model. Minimization of energy consumption in both extractive and regeneration columns is attempted. Optimal operating parameters of the process including glycol concentration in the solvent mixture, main feed, and entrainer feed trays, total number of theoretical trays, and heat supplied to the reboiler are determined in order to achieve a specified distillate purity of 99.9 mol % ethanol.
Comparison of the Activity of a Rhodium‐Biphephos Catalyst in Thermomorphic Solvent Mixtures and Microemulsions
Authors: Rost Anke , Brunsch Yvonne , Behr Arno , Schomäcker Reinhard 
Published: May 2014

AbstractTunable solvent systems provide optimal reaction conditions for homogeneous catalysis as well as appropriate conditions for separating the product from the catalyst via temperature switches. Two tunable solvent systems are presented based on different thermodynamic concepts, namely thermomorphic multicomponent solvent systems and dispersions of immiscible liquids, stabilized by nonionic surfactants as microemulsions. Both systems were applied for the regioselective hydroformylation of the model substrate 1‐dodecene with a Rhodium/ligand catalyst system. The accessibility of the catalyst for the reactants was compared between the molecularly dispersed mixtures and the colloidally dispersed microemulsion systems which are heterogeneous on the microscopic level.
