Preliminary results and economics of the New York University process: continuous acid hydrolysis of cellulose, producing glucose for fermentation
The title process for the continuous acid hydrolysis of cellulose to glucose was evaluated in both batch- and pilot plant-scales. The optimal temperature and reaction time for batch-scale dilute acid hydrolysis were 232 degrees and 10-20 s, respectively. Comparison of glucose yield from newspaper pulp (10% solids) with sawdust (95% solids) as feedstock indicated that 50-60% conversions of alpha-cellulose to glucose were possible on a pilot-plant scale. Acceptable recovery of glucose (greater than 90%) was best accomplished by centrifugation at glucose concentrations of less than 4% from a 30% solids cake. In general, favorable results with respect to sugar yield and energy consumption were obtained.
