Abstract:

This assessment focuses on the gasification process step which converts a biomass-derived intermediate called slurry into synthesis gas (syngas) for subsequent synthesis of fuel and chemicals. The slurry is produced by fast pyrolysis plants and is processed in a pressurized entrained flow gasifier. The resulting syngas is conditioned and cleaned before it is converted in a Fischer-Tropsch or dimethyl ether synthesis in order to complete a biomass-to-liquid (BtL) production such as the considered bioliq® concept which is currently under development at the Karlsruhe Institute of Technology (KIT). This two-stage concept allows economic transportation of biomass over long distances due to the relatively high energy density of the slurry produced in multiple decentralized plants and economies of scale in the centralized gasification and synthesis stage. Different process configurations regarding operating pressure, gasification agent, syngas conditioning and feedstock composition of a commercial scale gasification plant for the production of clean syngas are analyzed from an energetic and economic point of view.
