Anaerobic Biodegradation of Biofuels (Ethanol and Biodiesel) and Proposed Biofuels (n-Propanol, iso-Propanol, n-Butanol)

摘要

Biofuels, such as ethanol and biodiesel, are a growing component of the nation’s fuel supply. Ethanol is the primary biofuel in the US market, distributed as a blend with petroleum gasoline, in concentrations ranging from 10% ethanol (E10) to 85% ethanol (E85). Biodiesel, made from soybean oil or other vegetable oils or from waste cooking fats, is also available in the U.S. market. Other compounds including n-propanol, iso-propanol, and n-butanol have been proposed as biofuels, but at present have not achieved an important share of the US market.
