Rheological behavior of uncured styrene‐butadiene rubber at low temperatures, pure and filled with carbon black

18.04.2015 | Alice Crié, Claire Baritaud, Rudy Valette, Bruno Vergnes, Polymer Engineering and Science, 2015

The flow behavior of an uncured styrene‐butadiene rubber (SBR) has been studied by using a specific preshearing capillary rheometer in the range of temperatures encountered in extrusion, i.e. between 40°C and 90°C. A pure SBR and various SBR compounds filled with different amounts of carbon ...


Influence of process parameters on sorption capacity of microwave activated biosorbents for urea recovery from human urine: a comparative study

10.04.2015 | M. Ganesapillai, A. Venugopal, V. Ananthkrishna, N. Tapankrishna, Asia-Pacific Journal of Chemical Engineering, 2015

Abstract The present investigation elicits a comparative study for recovering urea from human urea via adsorption onto three biosorbents: Microwave Activated Carbonized Bamboo Shoots (MACBS), Walnut Shells (MACWS) and Coconut Shells (MACCS). The rate of sorption was investigated under ...


Statistical Optimization for Production of Light Olefins in a Fluidized‐Bed Reactor

09.04.2015 | Hassan Sharifi Pajaie, Majid Taghizadeh, Chemical Engineering & Technology, 2015

Abstract The methanol‐to‐olefins reaction (MTO) was studied in a small‐scale fluidized‐bed reactor over synthesized silicoaluminophosphate (SAPO‐34) catalysts. Mesoporous nanocrystalline SAPO‐34 molecular sieves were synthesized hydrothermally by ultrasonic and microwave‐assisted aging ...


Effect of Catalyst, Temperature, and Hydrogen Pressure on Slurry Hydrocracking Reactions of Naphthalene

09.04.2015 | Solmaz Akmaz, Pegah Amiri Caglayan, Chemical Engineering & Technology, 2015

Abstract Hydrocracking reactions of naphthalene were investigated in a slurry‐type reactor with different catalyst compositions consisting of iron‐based compounds, metal oxides, and elementary sulfur in order to evaluate the most efficient catalyst composition. The reactions were repeated with ...


Generation of Crystalline Microcontainers of Salicylic Acid

08.04.2015 | Julia Seidel, Joachim Ulrich, Chemical Engineering & Technology, 2015

Abstract The formation of liquid inclusions is frequently observed to be disrupting in crystallization processes. But such crystals containing liquid inclusions might offer the possibility to be used as container systems by encapsulating other substances inside the inclusions. Experimental ...


Crystallization of Terutroban Sodium Salt Hydrate from the Deliquescent State

08.04.2015 | Nicolas Couvrat, Yohann Cartigny, Julie Linol, Lucile Vaysse‐Ludot, Pascal Langlois, Gérard Coquerel, Chemical Engineering & Technology, 2015

Abstract Terutroban sodium salt (Teru‐Na) is a solid active pharmaceutical ingredient initially produced in its anhydrous form. The crystallization of a new dihydrate was established using liquid‐assisted grinding and the liquid‐liquid interface process. The stability of the Teru‐Na ...


Fracture of unsaturated polyester and the limitation of layered silicates

28.03.2015 | Sina Chaeichian, Paula M. Wood‐Adams, Suong V. Hoa, Polymer Engineering and Science, 2015

In this work, we explain why the incorporation of organically modified nano‐clay into unsaturated polyester resins, unlike epoxy, does not improve their fracture toughness despite continuing aggressive research activities based on this approach. The mechanism behind this phenomenon is explored ...


Adsorption behavior of herbicide paraquat from aqueous solutions using starfish particles: kinetic, isotherm, and thermodynamic studies

27.03.2015 | Han Hao, Jianguo Feng, Weitao Chen, Sheng Xiang, Wenjun Liu, Xuemin Wu, Asia-Pacific Journal of Chemical Engineering, 2015

Abstract The adsorption of paraquat (PQ) on starfish particles was investigated to calculate the kinetic, isotherm, and thermodynamic parameters. The experiments were carried out as a function of particle size of adsorbent, adsorbent dosage, contact time, initial PQ concentration, stirring ...


Detection of decomposition for high pressure ethylene/vinyl acetate copolymerization in autoclave reactor using principal component analysis on heat balance model

16.03.2015 | G Sivalingam, Nipun J. Soni, Suketu M. Vakil, The Canadian Journal of Chemical Engineering, 2015

Abstract The autoclave reactor offers flexibility in producing specialty grades of ethylene/vinyl acetate copolymer at temperature range of 150‐230 °C and pressure range of 1400‐2000 kg/cm2. At such conditions, copolymerization is accompanied by decomposition of reactants which increases the ...


Effect of N2 pretreatment on the basicity, structural change, and isomerization activity of MgO and MgO/Mg(OH)2 catalysts

16.03.2015 | Prinyanee Suttibut, Kongkiat Suriye, Sirachaya Kunjara Na Ayudhya, Piyasan Praserthdam, Joongjai Panpranot, Asia-Pacific Journal of Chemical Engineering, 2015

Abstract As revealed by the X‐ray diffraction, basicity titration, and Fourier transform infrared spectroscopy results, changes in the structural properties, basicity, and isomerization activities were observed on the MgO catalysts upon N2 pretreatment at 325 °C followed by isomerization ...
