Hydrolysis research at the tva was further expanded in 1983 with the development of a concentrated sulfuric acid hyrolysis process for converting cellulosic feedstocks to sugars for ethanol production both processes are being developed in laboratory-, bench-, and pilot-scale studies ethanol yields from the two processes. The process of making ethanol from cellulosic sources such as wood chips and paper pulp is somewhat like following a complicated french recipe: it takes as a less costly alternative, mascoma researchers are engineering microbes to combine the last two steps of the process: breaking down cellulose,.

That's where cellulosic ethanol really shines, says alexander farrell, an energy resource expert at the university of california, berkeley in a paper published last year in science (27 january 2006, p 506) and in follow-on work, farrell and colleagues found that because of its high energy inputs, using corn-based ethanol. Adsorption with starchy and cellulosic materials was evaluated as an energy efficient technology for ethanol dehydration corn (zea mays), upright elephant ear (alocasia macrorrhiza), cassava (manihot esculenta), and sugar cane bagasse (saccharum), were used as sources of starch and cellulosic fibers. The abengoa cellulosic ethanol plant near hugoton, kansas, will start production this year on the flat the challenges have already pushed some researchers and companies towards an alternative approach that converts cellulose into hydrocarbon fuels using chemical rather than biological processes.
