The production of fuel grade alcohol by fermentation from sugars obtained by the acid hydrolysis of cellulose has been hindered by costly methods of cleansing the acid in the sugar stream. An economical and environmentally acceptable acid-sugar separation process based on ion exclusion chromatography has been developed and analyzed. This process recovers the acid for reuse in hydrolysis without producing landfill waste allowing a concentrated acid hydrolysis process to be commercially feasible.
