This book was released on 2006 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: As the worldwide demand for energy continues to experience substantial increases, greater portions of this demand are expected to be fulfilled through the use of cheap and abundant fossil fuels; most notably coal. The combustion of coal releases large amounts of polluting nitric oxide and considerable efforts have been made in developing carbon sorbent technologies that remove these pollutants from coal combustion flue gases so that the use of coal as an energy source can become as environmentally friendly as it is economically practical. These technologies utilize heterogeneous reaction chemistry in decomposing the oxides of nitrogen through the use of both catalytic and non-catalytic reactions with carbon. This dissertation aims to model reactor systems that will hopefully utilize such technology. The purpose of this dissertation has two primary components: to develop and validate thorough and accurate models that link together, as effectively as possible, both theory and experiment, in describing the heterogeneous reduction behavior of nitric oxide through activated carbon sorbents; and to determine a set of kinetic parameters for use by these models that produce simulated results that closely matched those that were experimentally measured. These models are large systems of coupled ordinary differential equations in time and partial differential equations in space and time. The partial differential equations of a given system are discretized in space producing a large set of ordinary differential equations and the combined set of ordinary differential equations was integrated in time to yield the solution. The focus in this development has been on both the qualitative and quantitative aspects in the modeling of such reaction chemistry and in the utilization of such chemistry in both thermo gravimetric analysis (TGA) reactor and packed bed reactor (PBR) systems that decompose nitric oxide. Separate first and second order sensitivity systems were derived from the TGA reactor models to describe how sensitive the operation of the TGA reactor was to the kinetic parameters used to model the NO reduction chemistry. These sensitivity systems are large systems of coupled ordinary/partial differential equations that were solved in the same manner as the reactor models were solved. These separate models were used in an iterative optimization procedure that utilized a subspace trust region interior Newton- reflective method whose objective was to obtain a set of kinetic parameters that produces model simulated results that closely matched those that were experimentally measured with the TGA reactor. The set of kinetic parameters obtained from this procedure was then used with the reactor models to simulate sets of experiments conducted with the TGA and PBR systems. The results of these simulations closely matched the data of the corresponding experiments that were experimentally measured.

Book excerpt: Gas-Solid Reactions describes gas-solid reaction systems, focusing on the four phenomena—external mass transfer, pore diffusion, adsorption/desorption, and chemical reaction. This book consists of eight chapters. After the introduction provided in Chapter 1, the basic components of gas-solid reactions are reviewed in Chapter 2. Chapter 3 describes the reactions of individual nonporous solid particles, while Chapter 4 elaborates the reaction of single porous particles. Solid-solid reactions proceeding through gaseous intermediates are considered in Chapter 5. Chapter 6 deals with the experimental approaches to the study of gas-solid reaction systems. How information on single-particle behavior may be used for the design of multiparticle, large-scale assemblies, and packed- and fluidized-bed reaction systems is deliberated in Chapter 7. The last chapter covers the specific gas-solid reaction systems, including some statistical indices indicating the economic importance of the systems and processes it’s based on. This publication is recommended for practicing engineers engaged in process research, development, and design in the many fields where gas-solid reactions are important.

Download or read book Reaction Engineering Principles written by Himadri Roy Ghatak and published by CRC Press. This book was released on 2018-09-03 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical reaction engineering is at the core of chemical engineering education. Unfortunately, the subject can be intimidating to students, because it requires a heavy dose of mathematics. These mathematics, unless suitably explained in the context of the physical phenomenon, can confuse rather than enlighten students. Bearing this in mind, Reaction Engineering Principles is written primarily from a student’s perspective. It is the culmination of the author’s more than twenty years of experience teaching chemical reaction engineering. The textbook begins by covering the basic building blocks of the subject—stoichiometry, kinetics, and thermodynamics—ensuring students gain a good grasp of the essential concepts before venturing into the world of reactors. The design and performance evaluation of reactors are conveniently grouped into chapters based on an increasing degree of difficulty. Accordingly, isothermal reactors—batch and ideal flow types—are addressed first, followed by non-isothermal reactor operation, non-ideal flow in reactors, and some special reactor types. For better comprehension, detailed derivations are provided for all important mathematical equations. Narrative of the physical context in which the formulae work adds to the clarity of thought. The use of mathematical formulae is elaborated upon in the form of problem solving steps followed by worked examples. Effects of parameters, changing trends, and comparisons between different situations are presented graphically. Self-practice exercises are included at the end of each chapter.

Available in PDF, EPUB and Kindle. Book excerpt: Biomass can be converted to energy, biofuels, and bioproducts via thermochemical conversion processes, such as combustion, pyrolysis, and gasification. Combustion technology is most widely applied on an industrial scale. However, biomass gasification and pyrolysis processes are still in the research and development stage. The major products from these processes are syngas, bio-oil, and char (called also biochar for agronomic application). Among these products, biomass chars have received increasing attention for different applications, such as gasification, co-combustion, catalysts or adsorbents precursors, soil amendment, carbon fuel cells, and supercapacitors. This Special Issue provides an overview of biomass char production methods (pyrolysis, hydrothermal carbonization, etc.), characterization techniques (e.g., scanning electronic microscopy, X-ray fluorescence, nitrogen adsorption, Raman spectroscopy, nuclear magnetic resonance spectroscopy, X-ray photoelectron spectroscopy, and temperature programmed desorption and mass spectrometry), their properties, and their suitable recovery processes.
