Kerr, Gerald C. Shurson, Lee J. Johnston and William A. Dozier, III Preface The use of biodiesel worldwide is becoming increasingly important, because of the widespread shortage of oil resources, which has raised the prices of fossil fuels. This biofuel also offers an opportunity to meet the energy demands with less impact to the environment due its renewable characteristics. This book entitled "Biodiesel – Quality, Emissions and By-Products" comprises 20 chapters and covers topics related to biodiesel quality, performance of combustion engines that use biodiesel, and the emissions they generate. It emphasizes the applications of glycerol, a byproduct of biodiesel production process. It is divided in three sections: i) Biodiesel Quality and Standards, ii) Biodiesel: Development, Performance and Combustion Emissions, and iii) Glycerol: Properties and Applications. The first section, Biodiesel: Quality and Standards is integrated by seven chapters. Chapter 1 presents the main standards on commercial biodiesel quality adopted in different regions of the world and the importance and significance of the main properties of biodiesel. Chapter 2 discusses the determination of photochemical properties, thermal diffusion, thermal conductivity and thermal effusivity as a promising route to characterize biodiesel oils. Chapter 3 explains how to characterize and differentiate each type of biofuel respect to the other ones by pressure differential scanning calorimetry. Chapter 4 comments that raw material source, impurities and production practices, can affect the quality of the biodiesel, performance and commercial approval of the final product. Chapter 5 compares the performance of one commercial biodiesel and three laboratory-produced biodiesels to verify the effect of storage temperature, type of storage container, storage time, as well as the moisture content on the properties of the biodiesel. Chapter 6 describes a method for sample preparation and quantification of FAME in diesel, and Chapter 7 details a research about standardization of procedures used for metal trace in biodiesel. The second section, Biodiesel: Development, Performance and Combustion Emissions include eight chapters. Chapter 8 is a study of biodiesel and food balance, and how they represent opportunities for agriculture and rural development. Chapter 9 describes several studies for producing biodiesel from raw materials native of Baja California, Mexico. Chapter 10 presents the development of multifunctional detergent- dispersant additives based on fatty acid methyl esters. Chapter 11 discusses the results X Preface of a research on hydrogenation of fatty acid methyl esters to fatty alcohol. Chapter 12 is a review of impacts of biodiesel use as a fuel for diesel engines. Chapter 13 focuses on the toxicology of the compounds produced by the combustion of biodiesel. Chapter 14 depicts an assessment of the main properties of binary mixtures and triple mixtures between biodiesel from rapeseed oil, commercial diesel fuel and bioethanol compared to diesel fuel when were used in combustion engines. Chapter 15 exhibits the results of a research activity aimed at studying the high-blending biodiesel use in the “torque controlled” automotive diesel engines. In particular, based on the employment of an innovative biodiesel blending detection methodology, the capability of closed loop combustion control to improve both pollutant emissions and full load engine performance was investigated. The third section, Glycerol: Properties and Applications, focuses on this product obtained as a co-product of biodiesel. Chapter 16 is a review of reactions such as dehydration, hydrogenolysis, oxidation, etherification, and reforming including results obtained by the author. All these uses allow considering the glycerol as one key-compound in the environment of future biorefinery. Chapter 17 is a study about antioxidative and anticorrosive properties of glycerol. Chapter 18 summarizes the state-of-the-art glycerol-based biotechnological processes and discusses future developments. Chapter 19 presents the utilization of glycerol in biotechnological applications and Chapter 20 discusses some unusual applications of glycerol.
