Available in PDF, EPUB and Kindle. Book excerpt: Various aspects of the behaviour of fixed bed reactors supporting highly exothermic reactions, relevant to stable -optimal design and control, have been studied using detailed mathematical models. In order to establish the form of the simplest basic structure, two methods of describing radial heat transfer in two dimensional packed beds have been examined. It is shown that a lumped parameter single phase heat transfer model which implicitly incorporates the heterogeneous structure can account not only for the radial heat flux associated with both the fluid and solid phases but is also the more appropriate formulation since it allows the important reaction rate limitations due to intraparticle mass transfer to be properly estimated. Using this two dimensional, heterogeneous dynamic model of the reactor it has been possible to evaluate a simpler one dimensional formulation. It is shown that the latter gives an adequate-description of the dynamic behaviour of the system, provided that the overall heat transfer coefficient between the fluid and the coolant is suitably defined, and may, therefore, be used for general studies of reactor performance. Consideration has been-given to the response of the reactor to sinusoidal perturbations of the inlet conditions. It has been found that at certain frequencies of oscillation temperature runaway may develop before a safe quasi-stationary state is reached. A detailed examination of this behaviour has shown that in addition to the non-linear effects the difference in the speeds of propagation of the concentration and temperature waves along the reactor as a result of the heterogeneity of the system is also very significant. The effect of both cocurrent and countercurrent cooling of a single reactor tube has been examined. The behaviour for perturbations in coolant temperature is similar to that for inlet temperature and indicates potential difficulties in the design of control systems. A mathematical model of a multitubular reactor with crossflow cooling has been developed and used to identify some of the problems which may arise in these systems. In particular, considerable interaction between the individual reactor tubes occurs when significant conversion of the reactant takes place. This causes tubes in different parts of the bundle to exhibit different behaviour and with countercurrent cooling this may give rise to multiple steady states due to the feedback of heat within the system. A technique has been developed for predicting regions of parametric sensitivity and temperature runaway in heterogeneous fixed bed reactors. The relationship between this form of instability and that due to multiple states of the catalyst pellet has been demonstrated. Application of this method to both the design and control of a reactor is discussed and it is shown that it provides an insight as to the behaviour of the system since it makes possible the establishment of a relationship between local and global reactor stability and the operating variables.

Book Synopsis Catalytic Reactors by : Basudeb Saha
Download or read book Catalytic Reactors written by Basudeb Saha and published by Walter de Gruyter GmbH & Co KG. This book was released on 2015-12-18 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Catalytic Reactors presents several key aspects of reactor design in Chemical and Process Engineering. Starting with the fundamental science across a broad interdisciplinary field, this graduate level textbook offers a concise overview on reactor and process design for students, scientists and practitioners new to the field. This book aims to collate into a comprehensive and well-informed work of leading researchers from north America, western Europe and south-east Asia. The editor and international experts discuss state-of-the-art applications of multifunctional reactors, biocatalytic membrane reactors, micro-flow reactors, industrial catalytic reactors, micro trickle bed reactors and multiphase catalytic reactors. The use of catalytic reactor technology is essential for the economic viability of the chemical manufacturing industry. The importance of Chemical and Process Engineering and efficient design of reactors are another focus of the book. Especially the combination of advantages from both catalysis and chemical reaction technology for optimization and intensification as essential factors in the future development of reactors and processes are discussed. Furthermore, options that can drastically influence reaction processes, e.g. choice of catalysts, alternative reaction pathways, mass and heat transfer effects, flow regimes and inherent design of catalytic reactors are reviewed in detail. Focuses on the state-of-the-art applications of catalytic reactors and optimization in the design and operation of industrial catalytic reactors Insights into transfer of knowledge from laboratory science to industry For students and researchers in Chemical and Mechanical Engineering, Chemistry, Industrial Catalysis and practising Engineers
