Download or read book Mass Transfer with Chemical Reaction in Multiphase Systems written by E. Alper and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 1079 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of "mass transfer with chemical reaction" takes place whenever one phase is brought into contact with one or more other phases not in chemical equilibrium with it. This phenomenon has industrial, biological and physiological importance. In chemical process engineering, it is encountered in both separ ation processes and reaction engineering. In some cases, a chemical reaction may deliberately be employed for speeding up the rate of mass transfer and/or for increasing the capacity of the solvent; in other cases the multiphase reaction system is a part of the process with the specific aim of product formation. Finally, in some cases, for instance "distillation with chemical reaction", both objectives are involved. Although the subject is clearly a chemical engineering undertakin~, it requires often a good understanding of other subjects, such as chemistry and fluid mechanics etc., leading to publications in diversified areas. On the other har.d, the subject has always been a major field and one of the most fruitful for chemical engineers.

Download or read book The Oxidation of Cyclohexane written by I. V. Berezin and published by Elsevier. This book was released on 2018-04-12 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Oxidation of Cyclohexane focuses on the processes, methodologies, reactions, and approaches involved in the oxidation of cyclohexane. The publication first offers information on the theory of slow chain oxidations and the products of liquid-phase cyclohexane oxidation. Discussions focus on the applicability of the stationary state method to liquid-phase oxidation reactions; mechanism of liquid hydrocarbon chain oxidation; kinetic equations for product accumulation in degenerate branching chain reactions; and changes of the volume of the liquid phase due to oxidation product formation. The text then ponders on experimental apparatus for the study of the liquid-phase oxidation of cyclohexane, including prevention of cyclohexane losses in the waste gases, explosion danger and problems of safety, and characteristics of gas sampling in cyclohexane oxidation apparatus. The manuscript takes a look at the kinetics of uncatalyzed cyclohexane oxidation and kinetics of cyclohexane oxidation in continuous flow systems. Topics include effect of temperature on the relative yield of cyclohexane oxidation products; kinetics of cyclohexane oxidation in a glass reactor; rate of oxygen absorption and accumulation of reaction products; ideal displacement reactor; and determination of diffusion factor. The publication is a dependable reference for readers interested in the oxidation of cyclohexane.

This book was released on 2018-01-23 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the combustion chemistry of cyclohexane, methylcyclohexane, and ethylcyclohexane on the basis of state-of-the-art synchrotron radiation photoionization mass spectrometry experiments, quantum chemistry calculations, and extensive kinetic modeling. It explores the initial decomposition mechanism and distribution of the intermediates, proposes a novel formation mechanism of aromatics, and develops a detailed kinetic model to predict the three cycloalkanes’ combustion properties under a wide range of conditions. Accordingly, the thesis provides an essential basis for studying much more complex cycloalkanes in transport fuels and has applications in engine and fuel design, as well as emission control.

Download or read book Chemical Synthesis Using Supercritical Fluids written by Philip G. Jessop and published by John Wiley & Sons. This book was released on 2008-07-11 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: For 'better solutions' - this practical guide describes how to take advantage of supercritical fluids in chemical synthesis. Well-established in extractions and materials processing, supercritical fluids are becoming increasingly popular as media for modern chemical syntheses. Historically, the application of compressed gases has been restricted mainly to the production of bulk chemicals. In the last decade, however, research has turned to exploiting the unique properties of supercritical fluids for the synthesis of fine chemicals and specialized materials. Now that the necessary equipment is more readily available, the use of supercritical fluids should become more widespread in both laboratory and industrial scale syntheses. More than merely a concise introduction to the properties of supercritical fluids, here leading experts give a thorough, up-to-date account of chemistry in these alternative media. In-depth scientific commentary, detailed reaction protocols, descriptions of necessary equipment, and an outline of spectroscopic techniques add to the value of this handbook aimed at innovative synthetic chemists.

Download or read book Computational Methods in Multiphase Flow V written by Andrea Alberto Mammoli and published by WIT Press. This book was released on 2009 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Together with turbulence, multiphase flow remains one of the most challenging areas of computational mechanics and experimental methods and numerous problems remain unsolved to date. Multiphase flows are found in all areas of technology, at all length scales and flow regimes. The fluids involved can be compressible or incompressible, linear or nonlinear. Because of the complexity of the problems, it is often essential to utilize advanced computational and experimental methods to solve the complex equations that describe them. Challenges in these simulations include modelling and tracking interfaces, dealing with multiple length scales, modelling nonlinear fluids, treating drop breakup and coalescence, characterizing phase structures, and many others. Experimental techniques, although expensive and difficult to perform, are essential to validate models. This book contains papers presented at the Fifth International Conference on Computational Methods in Multiphase Flow, which are grouped into the following topics: Multiphase Flow Simulation; Interaction of Gas, Liquids and Solids; Turbulent Flow; Environmental Multiphase Flow; Bubble and Drop Dynamics; Flow in Porous Media; Heat Transfer; Image Processing; Interfacial Behaviour.

Download or read book Detailed Chemical Kinetic Modeling of Cyclohexane Oxidation written by and published by . This book was released on 2006 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: A detailed chemical kinetic mechanism has been developed and used to study the oxidation of cyclohexane at both low and high temperatures. Reaction rate constant rules are developed for the low temperature combustion of cyclohexane. These rules can be used for in chemical kinetic mechanisms for other cycloalkanes. Since cyclohexane produces only one type of cyclohexyl radical, much of the low temperature chemistry of cyclohexane is described in terms of one potential energy diagram showing the reaction of cyclohexyl radical + O2 through five, six and seven membered ring transition states. The direct elimination of cyclohexene and HO2 from RO2 is included in the treatment using a modified rate constant of Cavallotti et al. Published and unpublished data from the Lille rapid compression machine, as well as jet-stirred reactor data are used to validate the mechanism. The effect of heat loss is included in the simulations, an improvement on previous studies on cyclohexane. Calculations indicated that the production of 1,2-epoxycyclohexane observed in the experiments can not be simulated based on the current understanding of low temperature chemistry. Possible 'alternative' H-atom isomerizations leading to different products from the parent O2QOOH radical were included in the low temperature chemical kinetic mechanism and were found to play a significant role.
