Consequently, the yeast dies out when the solution reaches levels of about 15% ethanol.This means that the production of ethanol by fermentation is a batch process.Thanks to ethanol's boiling point, which is lower than that of water, the ethanol can then be separated from the rest of the solution by fractional distillation. Lignocellulosic biomass resources are renewable materials that can be converted to fermentable sugars and subsequently into ethanol. For details, see the Central Florida Pipeline Ethanol Project. As of the end of 2020, there was no commercial cellulosic ethanol production in the United States. The Process Cellulosic biomass is a complex mixture of carbohydrate polymers from plant cell walls known as cellu - lose and hemicellulose, plus lignin and a smaller amount of other com-pounds generally known as extrac-tives.
