Hydroprocessing Catalysts And Processes: The Challenges For Biofuels Production


Book Description

The demand for hydroprocessing catalysts has shown an increasing trend, because of their applications in refining of petroleum and biofuels, in order to comply with strict environmental regulations controlling emissions from transportation vehicles.Transport fuel is dominated by fossil fuels with carbon emission intensive production methods. If we are to move away from these sources, the alternative is to produce liquid fuels from agricultural stocks — crops, crop waste, forestry waste or algae. Converting these feedstocks into high quality fuels is a considerable challenge.By describing the current status in processing agricultural feedstock into high quality liquid transport fuels, the authors set out the means to develop better chemistry and catalysis for the necessary conversion processes. This book offers an intriguing insight into the mechanisms and protocols involved in new hydroprocessing catalysts and processes, and covers the methods for upgrading these liquids to modern transport vehicles suitable for operation in modern gasoline and diesel engines.It provides an introduction to the mechanism of hydroprocessing reactions, application of different metals in hydroprocessing, the effect of catalyst supports, applications in refining new feedstock, renewable fuels standards, the management of spent hydroprocessing catalysts, and hydrogen production.Hydroprocessing Catalysts and Processes will prove useful for both researchers in academe and industry concerned with future fuels development and treatment to produce current and future liquid transport fuels.




Production of Biofuels and Chemicals with Bifunctional Catalysts


Book Description

This book provides state-of-the-art reviews, current research, prospects and challenges of the production of biofuels and chemicals such as furanic biofuels, biodiesel, carboxylic acids, polyols and others from lignocellulosic biomass, furfurals, syngas and γ-valerolactone with bifunctional catalysts, including catalytic, and combined biological and chemical catalysis processes. The bifunctionality of catalytic materials is a concept of not only using multifunctional solid materials as activators, but also design of materials in such a way that the catalytic materials have synergistic characteristics that promote a cascade of transformations with performance beyond that of mixed mono-functional catalysts. This book is a reference designed for researchers, academicians and industrialists in the area of catalysis, energy, chemical engineering and biomass conversion. Readers will find the wealth of information contained in chapters both useful and essential, for assessing the production and application of various biofuels and chemicals by chemical catalysis and biological techniques.




Handbook of Spent Hydroprocessing Catalysts


Book Description

Handbook of Spent Hydroprocessing Catalysts, Second Edition, covers all aspects of spent hydroprocessing catalysts, both regenerable and non-regenerable. It contains detailed information on hazardous characteristics of spent and regenerated catalysts. The information forms a basis for determining processing options to make decisions on whether spent catalysts can be either reused on refinery site after regeneration or used as the source of new materials. For non-regenerable spent catalysts, attention is paid to safety and ecological implications of utilizing landfill and other waste handling and storage options to ensure environmental acceptance. As such, this handbook can be used as a benchmark document to develop threshold limits of regulated species. Includes experimental results and testing protocols which serve as a basis for the development of methodologies for the characterization of solid wastes Presents a database which assists researchers in selecting/designing research projects on spent catalysts, i.e., regeneration vs. rejuvenation and metal reclamation Provides the environmental laws, acts, and liabilities to raise awareness in safety and health issues in all aspects of spent catalysts Contains solid waste management procedures specific to hydroprocessing that serve as a model for designing research projects in other solid waste areas




Automotive Fuels Reference Book, Fourth Edition


Book Description

The earlier editions of this title have been best-selling definitive references for those needing technical information about automotive fuels. This long-awaited latest edition has been thoroughly revised and updated, yet retains the original fundamental fuels information that readers find so useful, This book is written for those with an interest in or a need to understand automotive fuels. Because automotive fuels can no longer be developed in isolation from the engines that will convert the fuel into the power necessary to drive our automobiles, knowledge of automotive fuels will also be essential to those working with automotive engines. Small quantities of fuel additives increasingly play an important role in bridging the gap that often exists between fuel that can easily be produced and fuel that is needed by the ever-more sophisticated automotive engine. This book pulls together in a single, extensively referenced volume, the three different but related topics of automotive fuels, fuel additives, and engines, and shows how all three areas work together. It includes a brief history of automotive fuels development, followed by chapters on automotive fuels manufacture from crude oil and other fossil sources. One chapter is dedicated to the manufacture of automotive fuels and fuel blending components from renewable sources, including e-fuels. The safe handling, transport, and storage of fuels, from all sources, are covered. New combustion systems to achieve reduced emissions and increased efficiency are discussed, and the way in which the fuels’ physical and chemical characteristics affect these combustion processes and the emissions produced are included. As CO2 is now an important emission there is also discussion regarding low and non-carbon fuels and how they might be used. There is also discussion on engine fuel system development and how these different systems affect the corresponding fuel requirements. Because the book is for a global market, fuel system technologies that only exist in the legacy fleet in some markets are included. The way in which fuel requirements are developed and specified is discussed. This covers test methods from simple laboratory bench tests, through engine testing, and long-term test procedures.

Applications Of X-ray Photoelectron Spectroscopy To Catalytic Studies: From Routine Analysis To Cutting-edge Surface Characterization


Book Description

X-ray photoelectron spectroscopy (XPS) has become a standard practice technique, and automated XPS facilities can be found in industry and in universities all over the world. This transformed XPS from an advanced characterization method for dedicated research, to a rather standard analysis technique of surface analysis. The catalyst's surface state is probably the most prominent factor that influences the catalytic performance. It is therefore no surprise that XPS has become an indispensable tool in studies of solid catalysts. It has been directly used to investigate issues such as the surface composition of the active catalyst and reaction and deactivation mechanisms.The objective of this book is to provide a comprehensive overview of the current status and future perspectives of X-ray photoelectron spectroscopy dedicated to catalytic applications, including thermal catalysis, electrocatalysis, and photo(electro)catalysis. The book contains 13 chapters, starting with the necessary introduction of the technique background, including basic phenomena and instrumentation aspects. The second part of the book focuses on the presentation of long-established applications of the technique, such as XPS studies of model catalysts. Finally, the book describes relatively recent developments of this method for cutting-edge surface characterization mainly using synchrotron X-ray radiation.
