Comparative techno-economic analysis of advanced biofuels, biochemicals, and hydrocarbon chemicals via the fast pyrolysis platform

摘要: ABSTRACTThis study evaluates the techno-economic feasibility of three product portfolios from a biomass fast pyrolysis biorefinery: biofuel, biochemicals, and hydrocarbon chemicals. The biorefinery design is based on five-stage fractionation system developed by Iowa State University. It can produce drop-in transportation fuels (biofuel scenario); infrastructure materials such as bioasphalt bio-cement, dextrose (biochemicals aromatics olefins (hydrocarbon chemicals scenario). Bio-oil fractionated into five stage-fractions upgraded through different pathways chosen portfolio. Minimum product-selling prices (MPSP) are calculated using 30-year discounted cash flow rate return analysis spreadsheet. Uncertainty via Monte-Carlo used to determine maximum investment cost (MIC) net present value (NPV) distribution.We estimate MPSPs US$3.09/gallon for biofuels, $433.7/MT $7...
