This book was released on 2022-01-26 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last two decades impressive advances have been made toward the understanding and quantitative description of the kinetics. Despite these advances, however, the use of mathematical modelling of gas-solid catalytic reactors in industry is still limited. By consolidating progress in the understanding of catalytic processes, this book applies these fundamental advances to the development of models for design, simulation and optimization of industrial reactors. Paying particular attention to the verification of the developed models against industrial data, these models are used to optimize the performance of many practical reactor cases. Using a systems approach for the development of the different components and the resulting overall models, the book is easy to read and gives an insight into the behaviour of these complex industrial systems. In addition, the practical relevance of bifurcation, instability and chaos to industrial reactors is briefly discussed.

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.

Available in PDF, EPUB and Kindle. Book excerpt: In the last decades the investigation methods of unsteady state catalytic processes have been widely developed by the response-technique methods. From this research emerged the realization that under unsteady state conditions and, especially under artificially created ones, it is possible to increase the productivity or selectivity of a catalyst or a catalytical process as a whole. The scientific literature in this field is mostly theoretical and aims at structuring and analysing mathematical models of unsteady state catalytical processes. In this book the theoretical and applied aspects of an efficiency of artificially created unsteady conditions in catalysis are discussed. It contains the lectures from researchers from all over the world that were held during the International Conference ''Unsteady State Processes in Catalysis'', 5--8 June 1990, Novosibirsk (USSR). Topics include: -- The problems of dynamics of a catalyst surface -- Kinetic models of unsteady processes -- Dynamics of chemical reactors -- Artificially created unsteady processes in a catalytic reactor.
