Facile one‐step synthesis of Nd‐doped BiOCl nanoparticles with the excellent photocatalytic behavior

07.07.2017 | Gnanaprakasam A., Sivakumar V. M., Thirumarimurugan M., Asia-Pacific Journal of Chemical Engineering, 2017

Abstract Pure and (1 and 2%) neodymium (Nd)‐doped BiOCl photocatalysts were successfully synthesized via facile one‐step solvothermal method. The structure, morphology, and composition of the synthesized materials were investigated by using X‐ray diffraction, field emission scanning electron ...


Solubility correlation of gall (Quercus infectoria) extract in supercritical CO2 using semi‐empirical equations

07.07.2017 | Hasmida Mohd Nasir, Liza Md Salleh, Ahmad Ramdan Ismail, Siti Machmudah, Asia-Pacific Journal of Chemical Engineering, 2017

Abstract The present work studied the solubilities of Quercus infectoria gall extract in supercritical carbon dioxide (SC‐CO2) system with the addition of methanol as polarity enhancer. Experimentally, the galls were extracted using SC‐CO2 at different operating pressures (20 to 30MPa) and ...


Effects of annealing temperature and time on decrepitation of lump coals and characteristics of resultant coal chars

06.07.2017 | Shengfu Zhang, Shuxing Qiu, Haijun Peng, Chenggong Sun, Liangying Wen, Jian Xu, Chenguang Bai, Asia-Pacific Journal of Chemical Engineering, 2017

Abstract The decrepitation of two Chinese lump coals was investigated using high‐temperature fast pyrolysis in a purpose‐designed furnace to simulate the reaction conditions in the coal‐based Corex ironmaking process, and evolution of functional group, porosity, crystallite structure as well ...


Effect of the Amount of Sludge on Physicochemical Properties and Chemical Structure of Low‐rank Coal under Hydrothermal Conditions

05.07.2017 | Meng Liu, Aderlanio Cardoso, Liang Zhao, Yufeng Duan, Asia-Pacific Journal of Chemical Engineering, 2017

Abstract Sewage sludge mixed with Yunnan low‐rank coal was treated by hydrothermal treatment (HT) at mild temperature and high‐pressure conditions. The fuel characteristics and chemical structure of HT solid products were investigated to explore the synergistic effects between low‐rank coal ...


Thermodynamic modeling of phase equilibrium of carbon dioxide clathrate hydrate in aqueous solutions of promoters and inhibitors suitable for gas separation

05.07.2017 | Venkata Ramana Avula, Pawan Gupta, Ramesh L. Gardas, Jitendra S. Sangwai, Asia-Pacific Journal of Chemical Engineering, 2017

Abstract Gas hydrates of CO2 in the presence of tetra‐n‐alkyl ammonium bromide (TBAB) and tetrahydrofuran (THF) show potential applications for storage. Prediction of the phase behavior of these systems is an important precursor for their successful application. In this work, a thermodynamic ...


Biochemical characterization of microalgae collected from north east region of India advancing towards the algae‐based commercial production

30.06.2017 | Ashmita Ghosh, Saumyakanti Khanra, Madhumanti Mondal, Thingujam Indrama Devi, Gopinath Halder, O.N. Tiwari, Tridib K ..., Asia-Pacific Journal of Chemical Engineering, 2017

Abstract Selection of suitable strain of microalgae is the crucial factor for large‐scale production of algae‐based products. Efforts have been made here for isolation, identification and biochemical characterization of five microalgae strains collected from Tripura (a small state in ...


Trade‐off between energy consumption and ethylene recovery rate for quasi‐plant wide operation optimization of the ethylene column with bottom circulatory system in ethylene complex

23.06.2017 | Dong Huang, Xiao‐Ying Zhao, Xiong‐Lin Luo, Asia-Pacific Journal of Chemical Engineering, 2017

Abstract Reducing energy consumption and increasing ethylene recovery rate can effectively optimize the operation of ethylene columns. This paper discusses the trade‐off between energy consumption and recovery rate in different scenes. For normal condition, the influences of energy consumption ...


Rapid and convenient removal of fluoride by magnetic magnesium–aluminum–lanthanum composite: Synthesis, performance and mechanism

14.06.2017 | Wei Zhao, Yuantao Chen, Wei Zhang, Asia-Pacific Journal of Chemical Engineering, 2017

Abstract By an easy co‐precipitation method, the magnetic magnesium–aluminum–lanthanum composite was successfully synthesized. The effects of the synthetic conditions such as Mg/Al/La molar ratio and calcination temperature on fluoride removal by the adsorbent were studied. The adsorbents were ...


Integrated two‐stage adsorption for selective removal of CO2 and SO2 by amine‐functionalized SBA‐15

14.06.2017 | L. Wei, Z. Gao, Y. Wang, Asia-Pacific Journal of Chemical Engineering, 2017

Abstract A novel process for integrated two‐stage selective removal of CO2 and SO2 from a simulated flue gas by an adsorption method was developed. Triethylolamine (TEA)‐loaded SBA‐15 was selected as the SO2 adsorbent, and tetraethylenepentamine (TEPA)‐loaded SBA‐15 was the CO2 adsorbent. ...


Developing PES membrane by modified Co3O4–OA nanoparticles for direct contact membrane distillation process

14.06.2017 | Nika Gholamzadeh, Majid Peyravi, Mohsen Jahanshahi, Hamzeh Hoseinpour, Ali Shokuhi Rad, Asia-Pacific Journal of Chemical Engineering, 2017

Abstract Modified hydrophobic cobalt oxide (Co3O4) nanoparticles were used to develop polyethersulfone (PES) nanocomposite membranes via phase inversion technique for direct contact membrane distillation (DCMD). Co3O4 nanoparticles were treated by oleic acid (OA) to decrease the surface energy ...
