Minimizing Ethanol Concentration In Organosolv Pretreatment For The Saccharification Of Loblolly Pine, Nelson B. Heringer
Minimizing Ethanol Concentration In Organosolv Pretreatment For The Saccharification Of Loblolly Pine, Nelson B. Heringer
Biological and Agricultural Engineering Undergraduate Honors Theses
Organic solvent pretreatment, commonly known as organosolv, is a method used to prepare biomass for enzymatic hydrolysis for the production of biofuels. This method common uses ethanol as the organic solvent. However, this creates an economic issue with the product stream, as ethanol becomes a product and input. This project sought to explore how decreasing the use of ethanol in organosolv pretreatment affected the recoverability of sugars after enzymatic hydrolysis. Loblolly pine (Pinus taeda L.) was pretreated at 170 °C for 60 minutes in 1% dilute sulfuric acid and an ethanol concentration varying from 65% to 35%. Compositional …
