A review of improving bioethanol production through optimization of KOHpretreatment

The reduction of non-renewable resources and their nonstop evacuation has become a majorconcern currently. The product of renewable energies from agricultural lignocellulose unneeded issustainable and economically possible. The pretreatment process is one of the most severe steps inthe bioethanol product, owing to the energy using and some expensive materials demand toseparate cellulose among hemicellulose, lignin and other compounds from lignocellulosicbiomass. Now, one of the highest obstacles to bioprocess commercialization is the low conversionof sugar from biomass, and potassium hydroxide pretreatment was suggested to ameliorate theEnzymatic Digestibility (ED) of biomasses. The modified ED through optimization of conditionis anticipated to contribute to developing the value of byproducts generated in food processing.this review, intended to probe the effect of using potassium hydroxide on different Research.
