Kinetics of the Esterification between Lactic Acid and Isoamyl Alcohol in the Presence of Silica Gel‐Supported Sodium Hydrogen Sulphate

03.01.2018 | Zhongkai Jiang, Jumei Xu, Zuoxiang Zeng, Weilan Xue, Shating Li, The Canadian Journal of Chemical Engineering, 2018

Abstract The esterification reaction between isoamyl alcohol and lactic acid was studied over silica gel‐supported sodium hydrogen sulphate (NaHSO4 · Silica). The influences of the external mass transfer, internal mass transfer, reaction temperature, catalyst loading, and initial reactant ...

Exploration of Ag Decoration and Bi Doping on the Photocatalytic Activity α‐ Fe2O3 under Simulated Solar Light Irradiation

21.12.2017 | Satheesh Rajamohan, Vignesh Kumaravel, Ahmed Abdel‐Wahab, Suganthi Ayyadurai, Rajarajan Muthuramalingam, The Canadian Journal of Chemical Engineering, 2017

Abstract In the present investigation, silver decorated and bismuth doped α‐Fe2O3 (Ag/Bi‐Fe2O3) was successfully synthesized using the co‐precipitation method. The size, shape, surface area, and magnetic properties were characterized by XRD, FE‐SEM, EDX, BET, VSM, and UV‐vis‐DRS techniques. ...

Bimetallic Bi‐Ni Oxides over Carbide Supports for Oxidative Dehydrogenation of n‐Butane: Experimental and Kinetic Modelling

21.12.2017 | Omer Elmutasim, G. Tanimu, Isam H. Aljundi, S. Al‐Khattaf, The Canadian Journal of Chemical Engineering, 2017

Abstract n‐butane oxidative dehydrogenation was studied over Bi‐Ni/TiC, Bi‐Ni/SiC, Bi‐Ni/ Silicalite‐1, and unsupported Bi‐Ni catalyst. The co‐impregnation technique was followed, with fixed 0.30 and 0.20 g/g for Bi and Ni respectively. The physico‐chemical properties were measured by means ...

Investigation of the Combination of TiO2 Nanoparticles and Drag Reducer Polymer Effects on the Heat Transfer and Drag Characteristics of Nanofluids

20.12.2017 | Paryani Sadra, S.A Ahmad Ramazani, The Canadian Journal of Chemical Engineering, 2017

ABSTRACT To compensate for drag increment due to the addition of nanoparticles to heat‐transfer fluids, it seems that one could add drag reducer polymeric agents to these fluids. So, in this work, experiments were carried out for solutions of two types of polyacrylamide (FLOPAAM 3330S and ...

Enhanced Adsorption of Xylenol Orange from Aqueous Solutions by Polyethylenimine‐Grafted Chitosan Microspheres

18.12.2017 | Xueqing Yu, Yingjun Jing, Hui Gao, The Canadian Journal of Chemical Engineering, 2017

Abstract To enhance the adsorption performance, chitosan microspheres (CS–MSs) were grafted with polyethylenimine (PEI), a cationic compound with abundant amine groups. The resulting PEI‐grafted CS–MSs (PEI–CS–MSs) were used for the adsorption of xylenol orange (XO), an anionic dye. The ...

Influence of atomization conditions on spray drying Lithium Iron Phosphate nanoparticle suspensions

18.12.2017 | Marco G. Rigamonti, Yu‐Xiang Song, He Li, Nooshin Saadatkhah, Pierre Sauriol, Gregory S. Patience, The Canadian Journal of Chemical Engineering, 2017

Abstract Removing solvents from nanoparticle solid suspensions requires the same diligence as drying pharmaceutical ingredients. LiFePO4 nanoparticles suspension in water oxidize, sinter, and Li3PO4 segregates on the surface when they dry in a furnace. Spray drying preserves the material ...
