Nowadays, biomass is proposed as a sustainable source for ultraclean liquid fuels production. Woody biomass is a promising and abundant hydrocarbon source with zero CO2 footprint. The two major processes explored for lignocellulosic biofuels production is catalytic pyrolysis and gasification followed by Fischer-Tropsch (FT) synthesis. In biomass catalytic pyrolysis aftertreatment of the resulting biooil is required to upgrade its quality (energetically and environmentally). In the gasification route, stand-alone biomass utilization is not economically and energetically feasible. Co-gasification with coal or natural gas results in feasible processes, but sulfur-rich syngas compositions. Mature syngas clean-up technologies (e.g., Rectisol) offer an overall efficient process for the production of clean, economic and efficient transportation fuels via FT synthesis. In this presentation, these two processes will be analyzed experimentally (catalytic pyrolysis) and computationally (gasification followed by FT) in terms of their CO2 footprint, thermodynamic efficiency, and composition in sulfur and nitrogen species.
