Abstract:
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 and is then processed in a single centralized pressurized entrained flow gasifier. The resulting syngas has to be conditioned and cleaned before it is converted in a DME or FT synthesis in order to complete the biomass-to-liquid (BtL) production. This two-stage concept allows the economic transportation of biomass over long distances, due to the relatively high energy density of the slurry produced in the first stage. In addition, reductions in specific investments and costs for further processing in the second stage are enabled by economies of scale. This study addresses possibilities for further process development and presents an outlook for a commercial implementation of biomass-derived fuels and chemicals.
