Thermochemical treatment of lignocellulosics for the production of ethanol

摘要: A method to process lignocellulosic biomass into ethanol under conditions of high loading is disclosed. Pretreatment was conducted at a concentration solids but with relatively low ammonia relative the dry weight biomass. The pretreated washed remove inhibitors and minimize carry-over subsequent steps saccharification fermentation. pretreated-washed ground some point prior saccharification. Enzymes are added allow liquification. More in fed-batch manner as proceeds ultimately obtain fermentation high-biomass get higher titer. amount such that achieves optimum hydrolysis sugars by enzymes.
