摘要：	The authors of H.R. 4 write that, 'The term renewable fuel means motor vehicle fuel that is produced from grain starch, oilseeds, or other biomass; or is natural gas produced from a biogas source, including a landfill, sewage waste treatment plant, feedlot, or other place where decaying organic material is found.' Although many known, and perhaps some unknown, renewable fuel sources qualify under the definition, through 2020 the requirement for renewable content of motor vehicle fuel is expected to be met primarily by ethanol blended into gasoline at volume fractions of 10 percent or lower. There are several ways to produce ethanol. H.R. 4 makes specific reference to emerging technology for conversion of cellulose to ethanol. Each gallon of ethanol produced from cellulosic feedstocks is to be counted as 1.5 gallons of renewable motor vehicle fuel. Ethanol can be produced from cellulose by conversion of the cellulose to sugar and fermentation. It can also be produced by gasification of cellulose and subsequent catalytic conversion to ethanol. Both technologies are still at the pilot stage. It is hoped that this credit for cellulose ethanol will accelerate its commercialization. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
