Membrane Reactors For Hydrogen Production Processes

Membrane Reactors for Hydrogen Production Processes deals with technological and economic aspects of hydrogen selective membranes application in hydrogen production chemical processes. Membrane Reactors for Hydrogen Production Processes starts with an overview of membrane integration in the chemical reaction environment, formulating the thermodynamics and kinetics of membrane reactors and assessing the performance of different process architectures. Then, the state of the art of hydrogen selective membranes, membrane manufacturing processes and the mathematical modeling of membrane reactors are discussed. A review of the most useful applications from an industrial point of view is given. These applications include: natural gas steam reforming, autothermal reforming, water gas shift reaction, decomposition of hydrogen sulphide, and alkanes dehydrogenation. The final part is dedicated to the description of a pilot plant where the novel configuration was implemented at a semi-industrial scale. Plant engineers, researchers and postgraduate students will find Membrane Reactors for Hydrogen Production Processes a comprehensive guide to the state of the art of membrane reactor technology.

In the last decade, the attention paid to the environmental protection has generated a considerable interest towards the development of new energy carriers and green energy production methods. Hydrogen as an energy carrier becomes a potential important source of energy due to its neutral environmental impact. However, its production, transformation and purification, presents a challenge in the so called hydrogen economy. Current Trends and Future Developments on (Bio-) Membranes gives a comprehensive review on the present state of the art of the hydrogen production and purification using new and alternative technologies stressing green processes and environment protection. The book covers green processes, renewable feedstocks utilization and membrane reactor technology for hydrogen production in line with new process intensification strategy. The book is divided in four sections, ie fundamentals of hydrogen generation, its impact on environmental issue, new applications involving hydrogen and its storage and distribution. The main scope of this book is to offer a new horizon on hydrogen generation and utilization. It stresses the role of new technologies for hydrogen generation, including the “micro-reactors technology for portable applications , their combination with high temperature fuel cells, the role of gas-separation for both hydrogen purification and CO2 sequestration, the exploitation of renewable sources (biogas, bioethanol and other renewables feedstocks) in reforming processes useful to generate hydrogen, membrane and membrane reactor technology as well as membrane bio-reactors etc. Presents process intensification and commercialization of new and alternative hydrogen generation technologies Relates new hydrogen production methods to their environmental impact Outlines the fundamentals of hydrogen generation Includes new developed technologies for hydrogen transport and storage

Membrane reactors are increasingly replacing conventional separation, process and conversion technologies across a wide range of applications. Exploiting advanced membrane materials, they offer enhanced efficiency, are very adaptable and have great economic potential. There has therefore been increasing interest in membrane reactors from both the scientific and industrial communities, stimulating research and development. The two volumes of the Handbook of membrane reactors draw on this research to provide an authoritative review of this important field. Volume 2 reviews reactor types and industrial applications, beginning in part one with a discussion of selected types of membrane reactor and integration of the technology with industrial processes. Part two goes on to explore the use of membrane reactors in chemical and large-scale hydrogen production from fossil fuels. Electrochemical devices and transport applications of membrane reactors are the focus of part three, before part four considers the use of membrane reactors in environmental engineering, biotechnology and medicine. Finally, the book concludes with a discussion of the economic aspects of membrane reactors. With its distinguished editor and international team of expert contributors, the two volumes of the Handbook of membrane reactors provide an authoritative guide for membrane reactor researchers and materials scientists, chemical and biochemical manufacturers, industrial separations and process engineers, and academics in this field. Discusses integration of membrane technology with industrial processes Explores the use of membrane reactors in chemical and large-scale hydrogen production from fossil fuels Considers electrochemical devices and transport applications of membrane reactors

Uniquely focussed on the engineering aspects of membrane reactors Provides tools for analysis with specific regard to sustainability Applications include water treatment, wastewater recycling, desalination, biorefineries, agro-food production Membrane reactors can bring energy saving, reduced environmental impact and lower operating costs

Hydrogen is one of the most promising next-generation fuels. It has the highest energy content per unit weight of any known fuel and in comparison to the other known natural gases it is environmentally safe - in fact, its combustion results only in water vapour and energy. This book provides an overview of worldwide research in the use of hydrogen in energy development, its most innovative methods of production and the various steps necessary for the optimization of this product.

Membrane reactors combine membrane functions such as separation, reactant distribution, and catalyst support with chemical reactions in a single unit. The benefits of this approach include enhanced conversion, increased yield, and selectivity, as well as a more compact and cost-effect design of reactor system. Hence, membrane reactors are an effective route toward chemical process intensification. This book covers all types of porous membrane reactors, including ceramic, silica, carbon, zeolite, and dense metallic reactors such as Pd or Pd-alloy, oxygen ion-conducting, and proton-conducting ceramics. For each type of membrane reactor, the membrane transport principles, membrane fabrication, configuration and operation of membrane reactors, and their current and potential applications are described comprehensively. A summary of the critical issues and hurdles for each membrane reaction process is also provided, with the aim of encouraging successful commercial applications. The audience for Inorganic Membrane Reactors includes advanced students, industrial and academic researchers, and engineers with an interest in membrane reactors.

Membranes already have important applications in artificial organs, the processing of biotechnological products, food manufacture, waste water treatment, and seawater desalination. Their uses in gaseous mixture separations are, however, far from achieving their full potential. Separation of air components, natural gas dehumidification and sweeting, separation and recovery of CO2 from biogas, and H2 from refinery gases are all examples of current industrial applications. The use of membranes for reducing the greenhouse effect and improving energy efficiency has also been suggested. New process intensification strategies in the petrochemical industry have opened up another growth area for gas separation membrane systems and membrane reactors. This two volume set presents the state-of-the-art in membrane engineering for the separation of gases. It addresses future developments in carbon capture and utilization, H2 production and purification, and O2/N2 separation. Topics covered include the: applications of membrane gas separation in the petrochemical industry; implementation of membrane processes for post-combustion capture; commercial applications of membranes in gas separations; simulation of membrane systems for CO2 capture; design and development of membrane reactors for industrial applications; Pd-based membranes in hydrogen production; modelling and simulation of membrane reactors for hydrogen production and purification; novel hybrid membrane/pressure swing adsorption process for gas separation; molecular dynamics as a new tool for membrane design, and physical aging of membranes for gas separations. Volume 2 looks at problems combined with membrane reactors.
