Abstract

This study presents the development of an expanded biorefinery processing network for producing biofuels that combines biochemical and thermochemical conversion platforms. The expanded network is coupled to a framework that uses a superstructure based optimization approach to generate and compare of a large number of alternatives at their optimal points. In this study the superstructure for thermochemical conversion route is formulated by using NREL studies of thermochemical conversion of biomass considering 3 biomass feedstocks, 2 products, 3 by-products and 18 processing intervals with combination of 72 processing intervals . This superstructure was integrated with an earlier developed superstructure for biochemical conversion routes thereby forming a
formidable number of biorefinery alternatives. The expanded network was demonstrated to be versatile and useful as a decision support tool for identifying at early stage optimal biorefinery concept with respect to technical, economic and environmental criteria.
