Abstract

This paper describes a continuous process of conversion of cellulose (and cellulose wastes) into ethanol by using acid hydrolysis of hemicellulose followed by enzymatic conversion of sugars. It is demonstrated that the development of the NYU continuous acid hydrolysis process has been most favorable. The characterization of preferred reaction conditions for both hemicellulose prehydrolysis and extraction followed by alpha -cellulose hydrolysis is continuing. Potential alcohol yield with hemicellulose utilization is estimated to increase 70% beyond that without prehydrolysis. A data base for the utilization of various waste cellulose feedstocks is being developed. Preliminary studies on the fermentation of waste cellulose acid hydrolyzates is underway.
