This article summarises the compatibility of six elastomers – used in fuel
storage and delivery systems – with test fuels representing gasoline blended
with up to 85% ethanol. Individual coupons were exposed to test fuels for four
weeks to achieve saturation. The change in volume and hardness, when wetted
and after drying, were measured and compared with the original condition.
The Energy Independence and Security Act (EISA) of 2007 was an omnibus energy policy law designed
to move the United States toward greater energy security and independence. A key provision of EISA is
the Renewable Fuel Standard (RFS) which requires the nation to use 36 billion gallons of renewable fuel
in vehicles by 2022. Ethanol is the most widely used renewable fuel, and a significant portion of the
36 billion gallon goal can be achieved by increasing the ethanol in gasoline to 15%. In fact in March
The Census of Agriculture, taken every five years, is a complete count of U.S. farms and ranches and the people who operate them. The Census looks at land use and ownership, operator characteristics, production practices, income and expenditures. For America’s farmers and ranchers, the Census of Agriculture is their voice, their future and their responsibility.
This report, generally referred to as the Billion-Ton Study or 2005 BTS, is an estimate of “potential” biomass available within the contiguous United States based on assumptions about inventory production capacity, availability, and technology.
The model is a vehicle fuel-cycle model for transportation systems. The model provides a set of outcomes that would involve feedstock production, biorefinery production, storage and consumer demand as the complete fuel-cycle. The data is internal to the model, but might be adaptive to different biofuels specifications. This model was developed by the Energy Systems Division at Argonne National Laboratory.
