英语翻译
As the price of current ethanol feedstocks (e.g.Corn) is estimated to increase,lignocellulosic materialsremain the only viable candidate to serve as renewable feedstock for ethanolproduction.There are huge amounts of wheat strawthat are currently burned on the field orwasted otherwise which can be used as low value rowmaterial for ethanol production.Despite extensive technological advances in ethanol production from lignocellulose feedstocksover last few decades the price of the secondgeneration ethanol is still high and remainsaround $2.65 per gallon (Kumar et al.,2009a,b).Thishigh price is because of some technological impediments encountered in all different steps of the process.
Pretreatment is estimated toaccount for 33% of the total cost (Tomas-Pejo et al.,2008).The current leading pretreatment methods forlignocellulosic materials are capital intensive.Economical comparison showedthat there is little differentiation between studied pretreatment methods asfor instance; low cost pretreatment reactors are counterbalanced by higher costof catalyst and/or ethanol recovery (Eggeman and Elander,2005).Development of less energy intensive andmore effective pretreatment methods allowing lower amount of enzymes loadingcan substantially decrease the total cost of cellulosic ethanol.
