There is increasing recognition that low-cost, high capacity processes for the conversion of biomass into fuels and chemicals are essential for expanding the utilization of carbon neutral processes, reducing dependency on fossil fuel resources, and increasing rural income. While much attention has focused on the use of biomass to produce ethanol via fermentation, high capacity processes are also required for the production of hydrocarbon fuels and chemicals from lignocellulosic biomass. In this context, this book provides an up-to-date overview of the thermochemical methods available for biomass conversion to liquid fuels and chemicals. In addition to traditional conversion technologies such as fast pyrolysis, new developments are considered, including catalytic routes for the production of liquid fuels from carbohydrates and the use of ionic liquids for lignocellulose utilization. The individual chapters, written by experts in the field, provide an introduction to each topic, as well as describing recent research developments.

The Rationale for Biofuels

1.1 The Rise of Petroleum
Biomass, for most of history, has been the primary energy source powering human development. This energy supply has taken various forms, including wood and dung for cooking and heating, charcoal for metallurgy, and animal feeds for food and transportation. With increasing concerns regarding human impacts on the environment, humanity is once again looking towards biomass resources to meet a significant portion of our energy needs. The challenges today in using biomass are many, but can best be related to scale and density. The scale of energy needed far exceeds all past demands; both the increasing world population and the energy intensity of modern life compound the need for energy as never before. Similarly, the distances over which energy is moved and the concentration of population into dense urban centers results in the need for fuels with high energy density to insure overall efficiency of use.
Over the past century, the developed world has enjoyed cheap and abundant energy supplies through the adoption of a fossil energy economy. The 1900s have been declared the "Petroleum Century", with both positive and negative connotations. The widespread use of petroleum allowed rapid economic expansion throughout the industrialized world, increasing national and personal affluence, and enabled the modern ideal of personal automobile ownership. With expanded automobile ownership came an increasing demand for liquid transportation fuels, a demand that led to a shift in primary production away from the consumer nations (chiefly the United States and Great Britain) to majority importation of fuels from more petroleum-rich areas of the world such as the Middle East and South America. As this shift from self-sufficiency to foreign dependence evolved over the latter half of the 20th century, the formation of the Organization of Petroleum Exporting Countries (OPEC) led to price stabilization and a nearly centralized control in oil output. However, in recent years, OPEC's market control has begun to wane, with expanded production in non-OPEC regions (including Central Asian Republics, Africa and South America) increasing worldwide supply of petroleum and limiting pricing pressures.
This trend away from OPEC dominance in production has been mirrored by a broadened international competition for access to energy, especially petroleum. The United States, consuming more than 25% of worldwide petroleum production by midcentury, was viewed as the dominant consumer to be appeased (or not) in price setting with the international standard for pricing being set in US dollars. However, as the 21st century opened, expanding energy demand in the developing nations, especially China and India with their very large populations, resulted in significant competition for access to petroleum internationally. This increased competition has led to a general upward trend in price and increased market volatility. As non-OPEC production has begun to decline, cooperation between international oil companies (who traditionally supply North America and Europe) and nationalized oil companies in the developing world, along with a renewed fear of OPEC dominance in control- ling worldwide supply, has resulted in a desire for decreased dependence on imported sources of energy.
Along with the increased affluence that resulted from the widespread use of fossil energy to power the economies of the western nations came undesirable environmental impacts related to the gaseous emissions from fossil-fuel combustion. At the turn of the century a general upward trend in global carbon-dioxide levels in the atmosphere was recognized. This led to international concerns over global climate change and other devastating impacts that might result from an increase in "greenhouse-gas" levels, chiefly carbon dioxide and methane, in the Earth's atmosphere. This concern is heightened when taking into account the scale and speed with which the developing nations of Asia are expanding fuel use, particularly petroleum and coal. As these nations adopt western ideals in vehicle ownership, petroleum usage will continue to rise, along with concomitant emissions from fossil-fuel combustion, if alternative fuels are not developed on a large scale.
1.2 Worldwide Demand for Liquid Fuels and the Impact of Non-OECD Asia
Worldwide, liquid fuels represent the most heavily utilized source of energy, as shown in Figure 1.1. The dominance of liquid fuels in the overall marketed energy portfolio is expected to continue well beyond 2030. This demand for liquids can be attributed primarily to transportation uses (see Figure 1.2), including automotive, marine bunker, and aviation fuels. Transportation demand for liquid fuels is unique in that demand is relatively unaffected by increases in price. The desire for personal transportation, Figure 1.3, well established in the Organization for Economic Cooperation and Development (OECD) member nations, is increasingly playing a significant role in...
