Book Description
Low-density polyethylene (LDPE) is a versatile polymer which is widely used both in domestic and industrial applications. About 50 % of commercial LDPE production around the world is carried out by free-radical polymerization initiated by organic peroxides in high-pressure tubular reactors. The free-radical polymerization is highly sensitive to even small changes in process conditions. As a result, the extreme pressures and temperatures in the high-pressure tubular LDPE reactor (HPTLR) present operational challenges to the plant engineer. A reliable model of the HPTLR will prove to be a valuable tool for the plant engineer in making decisions about reactor operations. In this work, a comprehensive dynamic model for the HPTLR has been developed for the prediction of reactor behavior. The model combines the power of CFD (computational fluid dynamics)-based modeling with the simplicity and intuition of CRE (chemical reaction engineering)-based micromixing models. The mathematical model is based on the finite-mode PDF (probability density function) approach to modeling turbulent reactive flows. The advantage of this approach is that the source terms in the model transport equations appear in closed form thus obviating the need for closure approximations which are common in (and the main shortcoming of) CRE-based reactor models . Some simplifying assumptions (which are found to be true in most cases of HPTLR operations) have been made, important among which is the assumption of fully-developed turbulent pipe flow. A two-environment model is used to describe micromixing. Free-radical mechanisms are considered for both LDPE polymerization reactions as well as ethylene decomposition reactions. Heat-transfer effects between the reactor tube and the coolant water jacket surrounding it are also considered. The resultant transport equations, which are convection-diffusion-reaction (CDR) -type partial differential equations, are numerically solved using a fractional time-stepping method. Model parameters have been estimated using plant data for both steady-state and dynamic behavior. Using experimental design techniques, the most influential parameters in the model have been determined. Dynamic behavior of the model under typical reactor operating conditions was studied. From our studies, we conclude that our model should prove to be an effective tool for the plant engineer in making critical plant-operation decisions.

Book Description
Clay–Polymer Nanocomposites is a complete summary of the existing knowledge on this topic, from the basic concepts of synthesis and design to their applications in timely topics such as high-performance composites, environment, and energy issues. This book covers many aspects of synthesis such as in- situ polymerization within the interlamellar spacing of the clays or by reaction of pristine or pre-modified clays with reactive polymers and prepolymers. Indeed, nanocomposites can be prepared at industrial scale by melt mixing. Regardless the synthesis method, much is said in this book about the importance of theclay pre-modification step, which is demonstrated to be effective, on many occasions, in obtaining exfoliated nanocomposites. Clay–Polymer Nanocomposites reports the background to numerous characterization methods including solid state NMR, neutron scattering, diffraction and vibrational techniques as well as surface analytical methods, namely XPS, inverse gas chromatography and nitrogen adsorption to probe surface composition, wetting and textural/structural properties. Although not described in dedicated chapters, numerous X-ray diffraction patterns of clay–polymer nanocomposites and reference materials are displayed to account for the effects of intercalation and exfoliations of layered aluminosilicates. Finally, multiscale molecular simulation protocols are presenting for predicting morphologies and properties of nanostructured polymer systems with industrial relevance. As far as applications are concerned, Clay–Polymer Nanocomposites examines structural composites such as clay–epoxy and clay–biopolymers, the use of clay–polymer nanocomposites as reactive nanocomposite fillers, catalytic clay-(conductive) polymers and similar nanocomposites for the uptake of hazardous compounds or for controlled drug release, antibacterial applications, energy storage, and more. The most comprehensive coverage of the state of the art in clay–polymer nanocomposites, from synthesis and design to opportunities and applications Covers the various methods of characterization of clay–polymer nanocomposites - including spectroscopy, thermal analyses, and X-ray diffraction Includes a discussion of a range of application areas, including biomedicine, energy storage, biofouling resistance, and more

Book Description
Algae Based Polymers, Blends, and Composites: Chemistry, Biotechnology and Material Sciences offers considerable detail on the origin of algae, extraction of useful metabolites and major compounds from algal bio-mass, and the production and future prospects of sustainable polymers derived from algae, blends of algae, and algae based composites. Characterization methods and processing techniques for algae-based polymers and composites are discussed in detail, enabling researchers to apply the latest techniques to their own work. The conversion of bio-mass into high value chemicals, energy, and materials has ample financial and ecological importance, particularly in the era of declining petroleum reserves and global warming. Algae are an important source of biomass since they flourish rapidly and can be cultivated almost everywhere. At present the majority of naturally produced algal biomass is an unused resource and normally is left to decompose. Similarly, the use of this enormous underexploited biomass is mainly limited to food consumption and as bio-fertilizer. However, there is an opportunity here for materials scientists to explore its potential as a feedstock for the production of sustainable materials. Provides detailed information on the extraction of useful compounds from algal biomass Highlights the development of a range of polymers, blends, and composites Includes coverage of characterization and processing techniques, enabling research scientists and engineers to apply the information to their own research and development Discusses potential applications and future prospects of algae-based biopolymers, giving the latest insight into the future of these sustainable materials
