The article highlights the production process for ethanol from wood chips. It is said that wood chips are pumped with hot water into the pretreatment reactor where hemicelluloses are isolated from lignin and cellulose. The hemicelluloses are processed through acidhydrolysis and are converted to monomer sugars through dilute sulfuric acid. It is noted that an economic assessment of the process was done based on data from the fourth quarter of 2012.
