Available in PDF, EPUB and Kindle. Book excerpt: A small-scale steam-methane reforming system for localized, distributed production of hydrogen offers improved performance and lower cost by integrating the following technologies developed at the University of Houston; (1) Catalyzed steam-methane reforming on ceramic foam catalyst substrates. (2) Coupling of reformers to remote heat sources via heat pipes instead of heating by direct-fired heaters. (3) Catalytic combustion of methane with air on ceramic foam substrates as the heat source. Each of these three technologies confer benefits improving the efficiency, reliability, or cost of an integrated compact steam-methane reforming system. A prior 2-D computer model was adapted from existing FORTRAN code for a packed-bed reactor and successfully updated to better reflect heat transfer in the ceramic foam bed and at the reactor wall, then validated with experimental heat transfer and reaction data for use in designing commercial-scale ceramic foam catalytic reactors. Different configurations and sizes of both reformer and combustor reactors were studied to arrive at a best configuration for an integrated system. The radial and axial conversions and temperatures of each reactor were studied to match the heat recovery capability of the reformer to the heat generation characteristics of the combustor. The vetted computer model was used to size and specify a 500 kg/day hydrogen production unit featuring ceramic foam catalyst beds integrated into heat pipe reactors that can be used for multiple end users, ranging from small edible fats and oils hydrogenators to consumer point of sale hydrogen fueling stations. The estimated investment for this 500 kg/day system is $2,286,069 but is expected to drop to less than $1,048,000 using mass production methods. Economic analysis of the 500 kg/day hydrogen production system shows that it is not presently competitive with gasoline as a transportation fuel, but the system is still economically attractive to stationary fuel cell applications or small chemical users with a delivered hydrogen price as low as $1.49/kg, even with a 10% IRR that includes investment recovery, depreciation, taxes, etc.

Book Synopsis The Hydrogen Economy by : National Academy of Engineering
Download or read book The Hydrogen Economy written by National Academy of Engineering and published by National Academies Press. This book was released on 2004-09-05 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The announcement of a hydrogen fuel initiative in the President's 2003 State of the Union speech substantially increased interest in the potential for hydrogen to play a major role in the nation's long-term energy future. Prior to that event, DOE asked the National Research Council to examine key technical issues about the hydrogen economy to assist in the development of its hydrogen R&D program. Included in the assessment were the current state of technology; future cost estimates; CO2 emissions; distribution, storage, and end use considerations; and the DOE RD&D program. The report provides an assessment of hydrogen as a fuel in the nation's future energy economy and describes a number of important challenges that must be overcome if it is to make a major energy contribution. Topics covered include the hydrogen end-use technologies, transportation, hydrogen production technologies, and transition issues for hydrogen in vehicles.
Book Synopsis Concepts In Syngas Manufacture by : Jens Rostrup-nielsen
Download or read book Concepts In Syngas Manufacture written by Jens Rostrup-nielsen and published by World Scientific. This book was released on 2011-07-21 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a general overview of syngas technologies as well as an in-depth analysis of the steam reforming process. Syngas is a mixture of hydrogen and carbon oxides which can be made from hydrocarbons, coal and biomass. It is an important intermediate in the chemical industry for manufacture of ammonia, methanol and other petrochemicals as well as hydrogen for refineries and fuel cells. Syngas is playing a growing role in the energy sector, because it can be converted into a number of important energy carriers and fuels. Syngas catalysis creates new options and flexibility in the complex energy network. The steam reforming process is the main technology today for manufacture of syngas. It is a complex intern-mingling of catalysis and heat transfer with restrictions caused by secondary phenomena such as carbon formation. Many of the principles are applicable for other gasification technologies of growing importance. Concepts of Syngas Preparation aims to provide a comprehensive introduction to this complex field of growing importance and gives a detailed analysis of the catalyst and process problems. This book also serves as an important link between science and industry by illustrating how the basic principles can be applied to solve design issues and operational problems./a

Book Synopsis The Fundamentals of Process Intensification by : Andrzej Stankiewicz
Download or read book The Fundamentals of Process Intensification written by Andrzej Stankiewicz and published by John Wiley & Sons. This book was released on 2019-06-13 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: This advanced textbook covering the fundamentals and industry applications of process intensification (PI) discusses both the theoretical and conceptual basis of the discipline. Since interdisciplinarity is a key feature of PI, the material contained in the book reaches far beyond the classical area of chemical engineering. Developments in other relevant disciplines, such as chemistry, catalysis, energy technology, applied physics, electronics and materials science, are extensively described and discussed, while maintaining a chemical engineering perspective. Divided into three major parts, the first introduces the PI principles in detail and illustrates them using practical examples. The second part is entirely devoted to fundamental approaches of PI in four domains: spatial, thermodynamic, functional and temporal. The third and final part explores the methodology for applying fundamental PI approaches in practice. As well as detailing technologies, the book focuses on safety, energy and environmental issues, giving guidance on how to incorporate PI in plant design and operation -- safely, efficiently and effectively.

Book Synopsis Efficient Reheating Concepts for a Reverse-flow Methane Reformer by : Carlos Tellaeche Herranz
Download or read book Efficient Reheating Concepts for a Reverse-flow Methane Reformer written by Carlos Tellaeche Herranz and published by Logos Verlag Berlin. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methane steam reforming is a well-established technology for the hydrogen production at industrial scale. For decentralized applications, the use of this energy intensive technology requires the development of novel, heat integrated reactor concepts. The adiabatic reverse-flow reformer is such a concept that enables to energetically couple the highly endothermic methane steam reforming with an exothermic combustion reaction using an asymmetric switching pattern, in which the operating conditions to run the production (reforming) and regeneration (combustion) steps alternate with every flow reversal. One of the main challenges for the technical realization of this concept is the efficient reheating of the packed bed at a high temperature level, avoiding excess temperatures that might damage the catalyst and the reactor itself. The present work tackles this aspect and describes the development of a combustion chamber to be embedded in the packed bed. The chamber is designed in order to enable its operation under the so called flameless oxidation conditions, in which flame formation during combustion is suppressed and hence, the highest temperatures attained limited. The successful realization of this concept and its potential to efficiently reheat the reverse-flow reformer under dynamic operation is experimentally demonstrated and reported. The experimental observations provide an insight into the potential, the limitations and the attainable performance of the system. These observations are supported by a series of detailed simulations. Besides enabling the analysis of alternative reactor configurations and switching patterns, the simulation results corroborate that the reverse flow-reformer studied experimentally is especially suited for the production of hydrogen in decentralized facilities.
