Combined Sustainability Assessment and Techno-Economic Analysis for the Production of Biomass-Derived High-Octane Gasoline Blendstock(PPT)

摘要

1. Produces a high-octane, gasoline-range (C5+), hydrocarbon product. 2. Leverages advances in syngas production and clean-up technologies developed for the thermochemical pathway from biomass to mixed alcohols, demonstrated in 2012. 3. Operates at lower severity conditions (lower operating temperature and pressure) relative to traditional methanol-to-gasoline (MTG) processes. 4. Combines homologation (-CH2- addition) and conversion of recycled C4-olefins and iso-paraffins to larger products in a single reactor system and does not require a separate alkylation step. 5. Possesses high selectivity to C7 (mostly 2,2,3-trimethylbutane and 2,2,3-trimethyl-but-1-ene) and C4 paraffins and olefins, which can be recycled to maximize yield of gasoline blendstock product. 6. Produces low aromatic-content product and has a low coke formation rate.
