“…Thermochemical biofuel production pathways offer opportunities for rapid and efficient 18 processing of diverse feedstock into fuel and chemicals (Adams et al, 2011;Brown, 2011;Haro 19 et al, 2013). Fast pyrolysis is a thermochemical process that can be used to convert 20 lignocellulosic biomass into three different products: bio-oil, biochar, and non-condensable gases 21 (NCG) (Kauffman et al, 2011).…”

This research focuses on the supply chain network design of a fast pyrolysis and hydroprocessing production pathway by utilizing corn stover as feedstock to produce gasoline and diesel fuel. A mixed integer linear programming (MILP) model was formulated to optimize fast pyrolysis and hydroprocessing facility locations and capacities to minimize total system cost, including the feedstock collecting costs, capital costs of facilities, and transportation costs. The economic feasibility of building a new biorefinery in Iowa was analyzed based on the optimal supply chain configuration and savings in bio-oil logistic costs to the centralized upgrading facility.

A two-stage batch hydrothermal process has been investigated with the aim of enhancing the yields of hydrogen and methane from sawdust. Samples of the sawdust were rapidly treated in subcritical water and with added Na 2 CO 3 (alkaline compound) and Nb 2 O 3 (solid acid) at 280 °C, 8 MPa. Each pre-processing route resulted in a solid recovered product (SRP), an aqueous residual and a small amount of gas composed mainly of CO 2 . In the second stage, the SRP and the liquid residuals were gasified in supercritical water in the presence of Ru/Al 2 O 3 catalyst for reaction times of up to 60 min for the SRP at 500 °C, 30 MPa. With the catalyst, carbon gasification efficiencies and methane selectivity increased with increasing reaction time. Overall, SRP from the Na 2 CO 3 pre-processing route produced 51% more hydrogen and 61% more methane than the original sawdust under identical reaction conditions. The cumulative yields of methane and hydrogen were 57.1 mol/kg, 42.5 mol/kg and 47.7 mol/kg, from Na 2 CO 3 , Nb 2 O 5 and neutral pre-processing routes, respectively. The combined yield of the two gases from direct SCWG of the original sawdust was 24.6 mol/kg. The entire process may re-present a stepchange in future energy production from biomass as the products from the first stage can be used as feedstocks for various other biomass conversion technologies.
