Abstract

The objective of this case study is to examine the economics of ethanol production using the Waterloo Fast Pyrolysis process integrated with a fermentation step. The raw materials considered are wood and switchgrass. The pyrolytic ethanol process is evaluated in terms of capital costs, operating costs, and ethanol production costs for each type of feedstocks used. Sensitivity analyses are carried out to study the uncertainties of feedstock costs, ethanol production rates and ethanol yields on ethanol production costs. The economics of pyrolytic ethanol is compared to two other widely-known processes: simultaneous saccharification and fermentation, and dilute acid hydrolysis and fermentation. This analysis indicates that the pyrolytic ethanol process is comparable with the other two processes and suggests that it should be considered for further development.
