A Comparative Study of Clogging in Valve and Cascade Mixers

22.04.2016 | Duanpeng Xie, Jinghong Zhou, Shizhe Tian, Leslaw Mleczko, Xinggui Zhou, Chemical Engineering & Technology, 2016

Abstract A cascade mixer and a valve mixer were applied for the precipitation of CaCO3. This model reaction has been used for benchmarking the both mixer types with respect to their robustness against fouling. It has been found that the valve mixer was much less susceptible to fouling and ...

Antifungal properties of chitosan–cobalt(II) complex and its potential on the suppression of damping‐off in cucumber seedlings

21.04.2016 | Xueqing Yu, Yingjun Jing, Wenchen Xia, Asia-Pacific Journal of Chemical Engineering, 2016

Abstract Chitosan–cobalt(II) complex (CTS–Co) was prepared by the complexation of chitosan with cobalt(II) ions. Fourier transform infrared spectra showed that the amine and secondary –OH groups of chitosan were involved in the complexation with Co(II) ions. The resultant CTS–Co exhibited ...

Benefits of microwave heating method in production of activated carbon

21.04.2016 | Azadeh B. Namazi, D. Grant Allen, Charles Q. Jia, The Canadian Journal of Chemical Engineering, 2016

Abstract This work investigates the chemical activation of a biochar sample using microwaves with KOH and NaOH. The activation of char samples was carried out in a microwave oven operating at 2.45 GHz with a power input of 1200 W. The specific surface area (SSA), yield (%), and pore size ...

Effects of particle size on the catalytic performance of MWCNTs supported alkalized MoS2 catalysts promoted by Ni and Co in higher alcohols synthesis

21.04.2016 | Ahmad Tavasoli, Rohollah M. Kiai, Ali Karimi, The Canadian Journal of Chemical Engineering, 2016

Abstract A series of nano‐sized alkalized MoS2 catalysts promoted by Ni and Co supported on multi‐walled carbon nanotubes (MWCNTs) were prepared via the reverse microemulsion technique with water to surfactant (W/S) molar ratios (molwater · mol−1surfactant) of 1–12. All prepared catalysts ...

Investigation into mean residence time and filling factor in flighted rotary torrefier

21.04.2016 | Daya R. Nhuchhen, Prabir Basu, Bishnu Acharya, The Canadian Journal of Chemical Engineering, 2016

ABSTRACT Torrefaction can upgrade the properties of biomass, making it similar to coal. This study develops an innovative indirectly heated two‐stage rotating drum‐type torrefier where biomass moves due to the rotation of inclined cylindrical reactors. The rotary reactors consist of three ...

Reduction of the elongation at break of thermoplastic polyolefins through melt blending with polylactide and the influence of the amount of compatibilizers and the viscosity ratios of the blend components on phase morphology and mechanics

20.04.2016 | Carolin Vogt, Hans‐Josef Endres, Jürgen Bühring, Henning Menzel, Polymer Engineering and Science, 2016

The objective of this work is the synthesis of a polypropylene/ethylene‐propylene‐rubber (TPO)/polylactide (PLA)/compatibilizer (PVM) blend to reduce the elongation at break of TPO by blending TPO with brittle PLA. Three TPO types with different viscosities were melt blended with PLA and an ...
