This book aims to provide the reader with useful information in the realm of biofuels such as biogas, biodiesel and bioethanol. This book is hoped to contribute to the consolidation of knowledge in the different fields. It briefly describes the use of biofuels just to use them as a source of energy. The expected energy produced can be used to replace energy obtained from nonrenewable fossil fuels such as petroleum. The problems caused from burning of fossil fuels such as petroleum, fire wood consumption which leads to deforestation, the health effects of humans as well as environment problems such as global warming, occurs due to the emission of greenhouse gases aspires me to write this book entitled as Biodiesel, Bio-ethanol and Biogas as an Alternative fuels. Generally, this book deals with the process of producing Biogas, Bio-ethanol and Biodiesel besides, the factors affecting the production of all these renewable energy sources. Based on this fact, anyone in the world can buy this book and use it as a reference book, to produce these energy sources from different wastes.
Current world fossil oil production is struggling to meet demand and may even show a decline after 2010. It is therefore necessary to develop new energy-efficient production pathways for transportation biofuels. This book offers an insight into three promising and innovative pathways for the biological production of ethanol, biogas and biodiesel. These unconventional methods should provide higher product yields, less stringent feedstock specifications, lower chemical additive demand, reduced waste production and much better energy balances when compared to more traditional methods. One pathway concerns the enzymatic production of a new kind of biodiesel where no glycerol waste is produced and an up to twenty percent higher product yield is obtained. The other two pathways are based on the biological conversion of syngas into ethanol or methane using various kinds of lignocellulosic biomass as the starting point. For each of the three pathways a comparison will be made with competing production methods. The contents reflect extended desktop research and show practical experimental results. Government scientists, academics and biofuel producers with an interest in novel transportation fuels will all find this book to be essential reading.
The residue from methane and alcohol production can be used in crop production-soil management systems. The four simpls steps listed below should be maintained for greatest utilization benefits: Know the chemical and physical characteristics of the residue. Know the chemical and physical characteristics of the soil to which the residue will be applied. Know the chemical and physical requirements of the crops to be grown. monitor the residue the soil and the crop to prevent unbalanced soil chemistry and potential crop production problems.
With increased public and scientific attention driven by factors such as oil price spikes, the need for increased energy security, and concerns over greenhouse gas emissions from fossil fuels, the production of fuels by biological systems is becoming increasingly important as the world seeks to move towards renewable, sustainable energy sources. Biofuels and Bioenergy presents a broad, wide-ranging and informative treatment of biofuels. The book covers historical, economic, industrial, sociological and ecological/environmental perspectives as well as dealing with all the major scientific issues associated with this important topic. With contributions from a range of leading experts covering key aspects, including: • Conventional biofuels. • Basic biology, biochemistry and chemistry of different types and classes of biofuel. • Current research in synthetic biology and GM in the development and exploitation of new biofuel sources. • Aspects relating to ecology and land use, including the fuel v food dilemma. • Sustainability of different types of biofuel. • Ethical aspects of biofuel production. Biofuels and Bioenergy provides students and researchers in biology, chemistry, biochemistry and chemical engineering with an accessible review of this increasingly important subject.
The importance of biofuels in greening the transport sector in the future is unquestionable, given the limited available fossil energy resources, the environmental issues associated to the utilization of fossil fuels, and the increasing attention to security of supply. This comprehensive reference presents the latest technology in all aspects of biofuels production, processing, properties, raw materials, and related economic and environmental aspects. Presenting the application of methods and technology with minimum math and theory, it compiles a wide range of topics not usually covered in one single book. It discusses development of new catalysts, reactors, controllers, simulators, online analyzers, and waste minimization as well as design and operational aspects of processing units and financial and economic aspects. The book rounds out by describing properties, specifications, and quality of various biofuel products and new advances and trends towards future technology.
Today the world is facing three critical problems: (i) High fuel prices, (ii) Climatic changes (iii) Air pollution. Currently there are several important problems to be resolved worldwide: (1) high need for energy, (2) high depletion of non-renewable energy resources and (3) high local and global environmental pollution. This book “Biofuels - A Promising alternate for next generation fuels” deals with the production of biofuels. The biggest difference between biofuels and petroleum feedstock is oxygen content. Biofuels have oxygen levels from 10% to 45% while petroleum has essentially none making the chemical properties of biofuels very different from petroleum. Oxygenates are just pre-used hydrocarbons having a structure that provides a reasonable antiknock value. Most traditional biofuels, such as ethanol from corn, wheat, or sugar beets, and biodiesel from oil seeds, are produced from classic agricultural food crops that require high-quality agricultural land for growth. The term biofuel is referred to as liquid or gaseous fuels for the transport sector that are predominantly produced from biomass. There are several reasons for biofuels to be considered as relevant technologies by both developing and industrialized countries. They include energy security reasons, environmental concerns, foreign exchange savings, and socioeconomic issues related to the rural sector. Biomass can be converted to biofuels through various methods like chemical, such as biomethanol and biodiesel production, thermochemical, such as bio-oil, bio-syngas, biohydrogen production, and biochemical, such as bioethanol, biogas, biodiesel and biohydrogen production.
