This work presents an economic feasibility study of an acid-hydrolysis-based ethanol plant. The site chosen was in Hawaii because of eucalyptus resources and liquid fuel market conditions. A plant site of 15 million gallons per year of denatured alcohol was selected. The base-case design used current commercial technology whereever applicable. The method was determined to be technically feasible, given significant by-product credits. R and D areas identified were pentose conversion to ethanol, lignin utilization, increase in reactor yield, and increased solids concentration. 56 refs., 33 figs, 23 tabs.
