美国2007年能源独立与安全法(EISA)确定了可再生燃料标准(RFS),RFS要求美国可再生燃料生产将从2008年的90亿加仑/年增加到2022年的360亿加仑/年。按照RFS要求,先进生物燃料的投资在4年内必须达到110×10~8 US(?),在10年内增加到460×10~8 US(?),在15年内增加到1 050×10~8 US(?)。在增加投资750×10~8 US(?)情况下,应使谷物乙醇产量达到150亿加仑/年。到2012年,先进生物燃料生产的增长将需要至少投运35套新的5 500万加仑/年生物燃料装置,到2017年达164
The United States of America Energy Independence and Security Act of 2007 (EISA) established the Renewable Fuel Standard (RFS) which requires US renewable fuel production to increase from 9 billion gallons / year in 2008 to 36 billion gallons / year by 2022. According to RFS, the investment in advanced biofuels must reach 110 × 10 ~ 8 US (?) In 4 years, increase to 460 × 10 ~ 8 US (?) In 10 years and increase to 1050 × 10 ~ 8 in 15 years US (?). With an additional investment of 750 × 10 ~ 8 US (?), Cereal ethanol production should reach 15 billion gallons / year. By 2012, the growth of advanced biofuels production will require the commissioning of at least 35 new 55 million gallon / year biofuel plants by 2017
