Download or read book Hydroprocessing Catalysts And Processes The Challenges For Biofuels Production written by Bo Zhang and published by World Scientific. This book was released on 2018-04-09 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Asymmetric Autocatalysis written by Kenso Soai and published by Royal Society of Chemistry. This book was released on 2022-10-28 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asymmetric autocatalysis is a reaction in which chiral compound acts as a chiral catalyst for its own production. The process is a catalytic automultiplication of the chiral compound leading to an end product with a high enantiomeric excess. It has advantages over non-autocatalytic reactions because the amount of catalyst increases and no loss or deterioration of the catalyst is observed. Additionally, because the catalyst and product have the same structure, the separation of product from the catalyst is not necessary. Asymmetric Autocatalysis provides a comprehensive introduction to the topic of autocatalysis and an in-depth review of the current state of the research. Edited by a team including Professor Kenso Soai, who first described these types of reaction, and written by experts from around the world this book is a great resource for anyone with an interest in organic synthesis, catalysis and chirality.

Download or read book Catalysis with Earth abundant Elements written by Uwe Schneider and published by Royal Society of Chemistry. This book was released on 2020-10-28 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Catalysis remains a key technology in a huge number of industrial processes in the 21st century. The catalytic properties of precious metals such as platinum and palladium are well understood. However, these metals are expensive and their supply is limited. Earth-abundant elements such as iron and nickel are, as the name suggests, in plentiful supply and much cheaper to use, but research on their use in catalysis has, historically, lagged behind. As researchers and companies increasingly look for ways to reduce costs and improve the sustainability of their processes there has been a renewed interest in these earth-abundant elements. This book presents a detailed overview of current research on the catalytic uses of the most Earth-abundant elements. Highlighting the top ten most Earth-abundant elements and their various roles in modern synthetic chemistry: s-block metals (Na, K, Mg, Ca), first-row transition metals (Ti, Mn, Fe), and p-block elements (Al, Si, P). The significant stoichiometric use of these elements, and their use as acid, base, dual, and/or redox catalysts will be discussed. It will be of use to industrial and academic researchers as well as graduate students with an interest in catalysis and sustainability.

This book was released on 2022-11-18 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an effort to reduce dependency on fossil fuel resources, biomass could essentially be converted into chemicals using high capacity processes. The Fischer–Tropsch Synthesis (FTS) pathway has been chosen as the focus of this book as it is a mature area, and unlike other pathways such as pyrolysis, FTS is a potential way of producing fuel/hydrocarbons with no sulfur, no nitrogen, and no heavy metals contamination, making it a good choice. Integrating technological development and business development rationales to highlight the key technological developments that are necessary to industrialize biofuels on a global scale, this book focusses on the key challenges that still hinder the effective biomass use and the realization of zero fossil fuel use. Traditional biomass to hydrocarbons pathways are covered, showcasing how they are tailored to yield a specific group of chemicals with the aim of reducing downstream processes. New developments are considered, including process synthesis, catalysts, and reactors, etc. Providing an up-to-date overview of the production of specialty chemicals and fuels from biomass via the Fischer–Tropsch Synthesis pathway, this title makes an excellent addition to the libraries of academics and practitioners working in catalysis and chemical engineering.
Download or read book Enantioselective Cobalt catalysed Transformations written by Hélène Pellissier and published by Royal Society of Chemistry. This book was released on 2018-08-15 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a foreword from leading organic chemist Professor Paul Wender, this book collects the major developments reported in the past thirty years in the field of enantioselective reactions promoted by chiral cobalt catalysts, illustrating the power of these green catalysts to provide all types of organic reactions from the basic to completely novel methodologies. The search for new methodologies to prepare optically pure products is one of the most active areas of research in organic synthesis. Of the methods available for preparing chiral compounds, catalytic asymmetric synthesis has attracted the most attention. In particular, asymmetric transition-metal catalysis is a powerful tool for performing reactions in a highly enantioselective fashion. Efforts to develop new asymmetric transformations have previously focused on the use of rare metals such as titanium, palladium, iridium and gold. However, the ever-growing need for environmentally friendly catalytic processes has prompted chemists to focus on the more abundant and less toxic first-row transition metals, such as cobalt, to develop new catalytic systems. The ability of cobalt catalysts to adopt unexpected reaction pathways has led to an impressive number of enantioselective cobalt-promoted transformations being developed over the past three decades. These have included the synthesis of many different types of products, often under relatively mild conditions and with remarkable enantioselectivities. This book is a useful reference resource for chemists, both academic and industrial, working in organic synthesis and interested in greener or more economical catalytic alternatives.
