The aim of this study is to model and assess different biomass-to-liquid (BtL) pathways for the production of fuels and chemicals via dimethyl ether (DME) synthesis as well as via Fischer-Tropsch (FT) synthesis. The conversion of lignocellulosic biomass, such as residual wood or straw, to synthetic fuels and chemicals is currently under development at the Karlsruhe Institute of Technology (KIT). Within the considered bioliq® concept, so-called slurry is produced by multiple decentralized fast pyrolysis plants...
