Explains how to overcome the economic challenges of biodiesel production
Chapter I: Renewable energy sources: a sustainable strategy for biodiesel productions.- Chapter II: Synthesis of biodiesel via alternative protocols.- Chapter III: Various multi-functional additives for biodiesel stabilization: Perspectives for more cost-effective and efficiency.- Chapter IV: Hydroxychalcones: Synthetic antioxidants for improving stability of biodiesel.- Chapter V: Fluorescence spectroscopy as an alternative analytical tool for monitoring biodiesel oxidative stability.- Chapter VI: Recent advances on sample preparation procedures for elemental determination in biodiesel.- Chapter VII: Alternative uses for biodiesel byproduct: Glycerol as a source of energy and high-value chemicals.
This book advances the use of biodiesel-more environmentally friendly than traditional fossil fuels-by showing how it can be synthesized at a lower cost, with greater efficiency and as a more pure and stable product. It presents methods based on fluorescence spectroscopy, which are less time-consuming than the traditional Rancimat analysis for monitoring stability, and are therefore less prone to allowing oxidative decay in the biofuel. Biodiesel exploits a variety of raw materials, from freshly harvested cottonseed to recycled cooking oil. These are cheap to produce and generate fuel lower in polluting sulphur and aromatic compounds than its petroleum-based equivalent. Beginning by addressing different protocols for synthesis based on fatty acids, methyl and ethyl esters, it then describes chemical analyses essential to establishing the purity of the biodiesel. It highlights in detail the use of multifunctional and synthetic antioxidants, and investigates the impact of synthetic chalcones and their derivatives on the oxidative stability of biodiesel.
The author goes on to explain how to ameliorate various influences - UV irradiation and metal contaminants for example - which increase the hazards of oxidation, such as degradation and instability. New pre-treatment procedures performed using ultrasonic energies, thermostatic bath and vortex stirring are not only more environmentally friendly, but cut down on the time-consuming process of determining metal content, and allow for the use of more environmentally friendly aqueous reagents. The book investigates and demonstrates these techniques on the basis of real-world results.
Further, it suggests the practical uses of byproducts of biodiesel production, for example, using glycerol as a source of energy and high valuable chemicals. These useful techniques aid any researcher exploring the production process of biodiesel and its stabilization and characteristics.
