    1. Application of Strong Porous Polymer Sheets for Superior Oil Spill Recovery

      Junaid Saleem, Alireza Bazargan, John Barford and Gordon McKay

      Article first published online: 23 JAN 2015 | DOI: 10.1002/ceat.201400068

      Natural and synthetic sorbents to control oil spills are increasingly demanded due to environmental concerns. Newly developed super oil sorbent polymer sheets made of porous ultrahigh-molecular-weight polyethylene provide exceptionally high uptake and retention capacities together with a mechanically strong structure. They are applicable in all types of oil spill sites.

    2. Copper Ion Cementation in Presence of a Magnetic Field

      Olfat A. Fadali, Mohamed Obaid, Mohamed S. Mahmoud, Taha E. Farrag, Kim TaeWoo, Khalil Abdelrazek Khalil and Nasser A. M. Barakat

      Article first published online: 21 JAN 2015 | DOI: 10.1002/ceat.201400153

      Relatively few reports are available on the effect of the direction of a magnetic field on an electrochemical process. Here, the copper cementation process was selected to investigate the effect of changing the direction of an electromagnetic field. The rate of cementation was enhanced in both parallel and perpendicular direction of the magnetic field with the latter being more effective.

    3. Discrete Modeling of Growth of Hairy Roots in a Mist Bioreactor

      Ritu Ranjan, Sambasiva Rao Katuri and Rajesh Khanna

      Article first published online: 21 JAN 2015 | DOI: 10.1002/ceat.201400402

      Industrial production of secondary metabolites from hairy roots remains challenging. A design strategy is developed to evaluate the impact of decisive parameters on the growth of hairy roots in a reactor by defining a discrete mathematical model. Its integration with spatio-temporal variation of nutrients in a reactor will be an essential contribution to large-scale production of hairy roots.

    4. Bed Expansion and Particle Classification in Liquid Fluidized Beds with Structured Internals

      Stella Piovano, Gabriel L. Salierno, Emiliano Montmany, Mauro D'Agostino, Mauricio Maestri and Miryan Cassanello

      Article first published online: 21 JAN 2015 | DOI: 10.1002/ceat.201400463

      Thumbnail image of graphical abstract

      A liquid-solid fluidized bed with internal allows extending the liquid velocity operation range before elutriation. A correlation to estimate the bed expansion in liquid-solid fluidized beds using structured packing as internals is proposed. Structured packing as internal in a liquid fluidized bed significantly favors classification of particles by density.

    5. Reactivation and Reuse of Platinum-Based Spent Catalysts for Combustion of Exhaust Organic Gases

      Zebao Rui, Shangren Wu, Hongbing Ji and Zili Liu

      Article first published online: 21 JAN 2015 | DOI: 10.1002/ceat.201400467

      Thumbnail image of graphical abstract

      Catalytic combustion of trace methane and toluene over a Pt-based spent catalyst modified by different pretreatment techniques was performed to assess the possibility of recycling the spent catalyst. NaBH4 solution treatment is a nondestructive and environmentally friendly method leading to better performance of the reactivated catalyst in comparison with the high-temperature gas treatment.

    6. Fouling Resistance on Chemically Etched Hydrophobic Surfaces in Nucleate Pool Boiling

      Longfei Hui, Mingyan Liu, Yongwei Cai and Yan Lv

      Article first published online: 8 JAN 2015 | DOI: 10.1002/ceat.201400194

      Thumbnail image of graphical abstract

      Surface topography and chemistry modifications are commonly applied to improve the pool boiling and anti-fouling performance of surfaces. Rough surfaces could enhance pool boiling but show higher fouling resistance. Highly hydrophobic micro- and nano-scale coating surfaces on stainless-steel substrates were fabricated and their performance in a pool boiling process was evaluated.

    1. Treating Methanol-to-Olefin Quench Water by Minihydrocyclone Clarification and Steam Stripper Purification

      Qiang Yang, Wen-jie Lv, Lei Shi and Hua-lin Wang

      Article first published online: 8 JAN 2015 | DOI: 10.1002/ceat.201400429

      Thumbnail image of graphical abstract

      The methanol-to-olefin (MTO) process is a still developing technology for producing ethylene and propylene from naphtha thermal cracking. Recovering MTO quench water by minihydrocyclone and steam stripping treatment is applied in industrial plants. The method and equipment for this system increase the economic efficiency of the MTO device and are applicable to other water treatment systems.

    1. Multiple Regression Analysis of Catalytic Dehydrogenation of Isopropanol in a Chemical Heat Pump System

      Mehmet Selçuk Mert, İnci Salt, Fatma Karaca, Hatice Hande Mert and Esen Bolat

      Article first published online: 22 DEC 2014 | DOI: 10.1002/ceat.201400277

      Thumbnail image of graphical abstract

      As a clean technology, chemical heat pumps are able to upgrade low-level thermal energy to upper levels and store energy without losses. Dehydrogenation of isopropanol can serve as a first step in such a system. The enhancing effects of Raney-Ni, Pt/C, and Ru/C type catalysts and alkaline NaOH additive on the dehydrogenation reaction of isopropanol were investigated statistically.

    2. Influence of Design Parameters on Hydrodynamics and Heat Transfer of a Modularized Millireactor

      Philip Biessey and Marcus Grünewald

      Article first published online: 22 DEC 2014 | DOI: 10.1002/ceat.201400645

      Thumbnail image of graphical abstract

      Reactors on a milli-scale open the possibility to develop modular equipment that allows for flexible production. An apparatus with rectangular product channels and mixing elements for process intensification is investigated in terms of hydrodynamics and heat transfer. The apparatus performs competitively with established reactor concepts and is, thus, an alternative for modular production units.

    3. Ultrasonic Hot Embossed Polymer Microreactors for Optical Measurement of Chemical Reactions

      Alexander Tollkötter, Johannes Sackmann, Tobias Baldhoff, Werner Karl Schomburg and Norbert Kockmann

      Article first published online: 4 DEC 2014 | DOI: 10.1002/ceat.201400522

      Thumbnail image of graphical abstract

      Ultrasonic hot embossing of chemically resistant polymers as a simple and cost-effective fabrication method of microstructures and an optical analysis tool for tracing the progress of chemical reactions are introduced and evaluated. The simplicity of the fabrication method itself and good similarities of produced polymer micromixers with conventional ones made of other materials are pointed out.
