Abstract: “A process where power and biomass are converted to Fischer-Tropsch liquid fuels (PBtL) is compared to a conventional Biomass-to-Liquid (BtL) process concept. Based on detailed process models, it is demonstrated that the carbon efficiency of a conventional Biomass to Liquid process can be increased from 38 to more than 90% by adding hydrogen from renewable energy sources. This means that the amount of fuel can be increased by a factor of 2.4 with the same amount of biomass. Electrical power is applied to split water/steam at high temperature over solid oxide electrolysis cells (SOEC). This technology is selected because part of the required energy can be replaced by available heat…”
Comments: the authors have developed in MATLAB a model of the Fischer-Tropsch reactors used in their study. The model is embedded in the MATLAB CAPE-OPEN Unit Operation wrapper from AmsterCHEM and plugged into Aspen HYSYS v9 where the remaining of the process flowsheet is modelled.
