Available in PDF, EPUB and Kindle. Book excerpt: Despite more than 200 years of sulfur research the chemistry of elemental sulfur and sulfur-rich compounds is still full of “white spots” which have to be filled in with solid knowledge and reliable data. This situation is parti- larly regrettable since elemental sulfur is one of the most important raw - terials of the chemical industry produced in record-breaking quantities of ca. 35 million tons annually worldwide and mainly used for the production of sulfuric acid. Fortunately, enormous progress has been made during the last 30 years in the understanding of the “yellow element”. As the result of extensive inter- tional research activities sulfur has now become the element with the largest number of allotropes, the element with the largest number of binary oxides, and also the element with the largest number of binary nitrides. Sulfur, a typical non-metal, has been found to become a metal at high pressure and is even superconducting at 10 K under a pressure of 93 GPa and at 17 K at 260 GPa, respectively. This is the highest critical temperature of all chemical elements. Actually, the pressure-temperature phase diagram of sulfur is one of the most complicated of all elements and still needs further investigation.

Available in PDF, EPUB and Kindle. Book excerpt: In the context of wastewater treatment, Bioelectrochemical Systems (BESs) have gained considerable interest in the past few years, and several BES processes are on the brink of application to this area. This book, written by a large number of world experts in the different sub-topics, describes the different aspects and processes relevant to their development. Bioelectrochemical Systems (BESs) use micro-organisms to catalyze an oxidation and/or reduction reaction at an anodic and cathodic electrode respectively. Briefly, at an anode oxidation of organic and inorganic electron donors can occur. Prime examples of such electron donors are waste organics and sulfides. At the cathode, an electron acceptor such as oxygen or nitrate can be reduced. The anode and the cathode are connected through an electrical circuit. If electrical power is harvested from this circuit, the system is called a Microbial Fuel Cell; if electrical power is invested, the system is called a Microbial Electrolysis Cell. The overall framework of bio-energy and bio-fuels is discussed. A number of chapters discuss the basics – microbiology, microbial ecology, electrochemistry, technology and materials development. The book continues by highlighting the plurality of processes based on BES technology already in existence, going from wastewater based reactors to sediment based bio-batteries. The integration of BESs into existing water or process lines is discussed. Finally, an outlook is provided of how BES will fit within the emerging biorefinery area.
Download or read book Sulfur written by Gerald Kutney and published by ChemTec Publishing. This book was released on 2007 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This attractive volume presents the history, characteristics, and uses for that vibrant yellow element, sulfur. Commercial sulfuric acid production from the early 16th century until today is reviewed, spanning the Ancient and Renaissance periods, the Industrial Age (to which sulfur was vitally important), and the Sulfur War of 1840. The book introduces "the Sulfur Age" and the processes of this period -- such as the Nordhausen, Bell and Leblanc methods --, then goes on to review native sulfur production in Sicily, once a major supplier to the world. Colorful characters abound here, including the Gabelloti, Doppioni, and wine merchants. The focus shifts to Frasch Sulfur production, with a portrait of Herman Frasch, his life and career, and a look at areas touched by his legacy (e.g., Texas, Mexico, Poland and Iraq). Moving to present day, the book presents "recovered" sulfur -- derived from sour gas and oil -- which constitutes 90% of today's elemental sulfur supply, and looks to Canada, a powerhouse supplier of Recovered Sulfur. An entire chapter is devoted to the modern-day sulfur entrepreneur, with a profile of various investors (from the reluctant to the private and institutional), and evaluates the benefits of adopting "revolutionary technologies". Finally, the book forecasts the sulfur industry's future and potential supply sources, such as worldwide oil sands. If you need a single, comprehensive book on sulfur, this is a book for your library.

Download or read book Organic Chemistry of Sulfur written by S. Oae and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years organic sulfur chemistry has been growing at an even faster pace than the very rapid development in other fields of chemistry. This phenomenal growth is undoubtedly a reflection of industrial and public demands: not only was sulfur recently in overall surplus for the first time in the history of the chemical industry but it has now become a prin cipal environmental hazard in the form of sulfur dioxide, sulfuric acid and hydrogen sulfide. Another reason, discernible in the last fifteen years, has been the desire, on the part of individual chemists and all types of research managers, to move away from the established chemistry of carbon into the less well understood and sometimes virgin chemistries of the other elements which form covalent bonds. As a result of this movement the last decade has seen the development of sulfur chemistry into a well-organized and now much better understood branch of organic chemistry. Enough of the detail has become clear to see mechanistic interrelationships between previously unconnected reactions and with this clarification the whole subject has in tum become systema tized and subdivided. The divalent sulfur chemistry of thiols, monosulfides, disulfides and polysulfides is a large area in itself, much of it devoted to oxidation-reduction and the breakage and formation of sulfur-sulfur bonds, although interesting discoveries are now being made about the reac tivity of certain sulfur-carbon bonds. Of course, this area has its own mas sive biochemical branch involving enzymes and proteins.
