Twenty Years of Trials, Tribulations, and Research Progress in Bioethanol Technology

摘要: The projected cost of ethanol production from cellulosic biomass has been reduced by almost a factor four over the last 20 yr. Thus, it is now competitive for blending with gasoline, and several companies are working to build first plants. However, technology development faced challenges at all levels. Because benefits bioethanol were not well understood, was imperative clarify differentiate its attributes. Process engineering invaluable in focusing on promising opportunities improvements, particularly light budget reductions, tracking progress toward goal. Now vital one or more commercial projects be successful, improving our understanding process fundamentals will reduce time costs commercialization. Additionally, must cut further as pure fuel open market, aggressive advances required meet this target.
