This article examines butanol and ethanol as transportation fuels for gasoline-powered engines. This paper examines two aspects. First, the fuel properties of butanol and ethanol are examined and compared to each other. Consequently, butanol overcomes three deficiencies of ethanol. Butanol has a higher energy content, butanol-gasoline blends do not separate in the presence of water, and butanol can be blended with gasoline in any percentage, all the way up to 100%. Second, a review of the fermentation technology is examined for both butanol and ethanol production. Both butanol and ethanol can be fermented from the same feedstocks, which include the sugar and starch crops and lignocellulosic fermentation from wood...
This research examines in detail the technology and economics of substituting biodiesel for diesel #2. This endeavor examines three areas. First, the benefits of biodiesel are examined, and the technical problems of large-scale implementation. Second, the biodiesel production possibilities are examined for soybean oil, corn oil, tallow, and yellow grease, which are the largest sources of feedstocks for the United States. Examining in detail the production possibilities allows to identity the extent of technological change, production costs, byproducts, and greenhouse gas (GHG) emissions. Finally, a U.S. agricultural model, FASOMGHG was used to predict market penetration of biodiesel, given technological progress,...
