The world is currently faced with two significant problems: fossil fuel depletion and environmental degradation, which are continuously being exacerbated due to increasing global energy consumption. As a substitute for petroleum, renewable fuels have been receiving increasing attention due a variety of environmental, economic, and societal benefits. The first-generation biofuels - ethanol from sugar or corn and biodiesel from vegetable oils - are already on the market. The goal of this book is to introduce readers to second-generation biofuels obtained from non-food biomass, such as forest residue, agricultural residue, switch grass, corn stover, waste wood, municipal solid wastes, and so on. Various technologies are discussed, including cellulosic ethanol, biomass gasification, synthesis of diesel and gasoline, bio-crude by hydrothermal liquefaction, bio-oil by fast pyrolysis, and the upgradation of biofuel. This book strives to serve as a comprehensive document presenting various technological pathways and environmental and economic issues related to biofuels.

Supercritical fluid extraction is an environmentally safe and cost-effective alternative to traditional organic solvents. Carbon dioxide is widely used as the solvent of choice for applications such as caffeine and nicotine extraction due to its mild critical temperature, nontoxicity, nonflammability, and low cost. Introducing the most complete collection of supercritical CO2 solubility data currently available, Solubility in Supercritical Carbon Dioxide features experimental data on more than 780 solutes in consistent units and an easily accessible format.This book reflects the authors’ painstaking efforts to compile solubility data for an extensive variety of compounds including liquids, solids, polymers, foods, drugs, nutraceuticals, pesticides, dyes, and metal complexes. Each of the more than 1200 tables is arranged in alphabetical order by compound, includes a graphical plot of its data, and features the following information: Compound name, molecular formula, and molecular weightTemperature and pressure given in Kelvin and bar, respectivelyName and amount of cosolvent, if applicableMolar or mass solubility, when applicableMole- or mass-fraction solubilitySynonyms for the compound, where availableReference source for the dataDensity data for CO2 appears in one appendix, while a complete list of solutes by molecular formula appears in the other. Clear, consistent, and carefully organized, Solubility in Supercritical Carbon Dioxide is the most convenient quick-lookup guide for reliable data.

From Methane to Hydrogen—Making the Switch to a Cleaner Fuel SourceThe world’s overdependence on fossil fuels has created environmental problems, such as air pollution and global warming, as well as political and economic unrest. With water as its only by-product and its availability in all parts of the world, hydrogen promises to be the next great fuel source. All of the Key Aspects of Hydrogen Fuel Hydrogen Fuel: Production, Transport, and Storage describes various aspects of hydrogen fuel, including production from both renewable and nonrenewable sources, purification, storage, transport, safety, codes, and carbon dioxide sequestration. The book examines the unique properties and uses of the hydrogen molecule, its ability to be produced from numerous energy sources, and its separation and purification. It explains how to transport hydrogen using pipelines and tankers, and how to store it using compressed tanks, metal hydrides, carbon adsorbents, and chemical hydrides. The expert contributors also discuss codes and standards, monitoring techniques, and safety designs. The Path to a Cleaner World and Energy Independence Focusing on a clean, economical alternative to nonrenewable energy, this volume provides the latest information on the hydrogen fuel economy.
