The aim of this project is to develop an economically efficient concept for production of valuable substances, such as Fischer-Tropsch-fuels or methanol, from lignite and a variety of wastes including plastics and bio-wastes by means of the High Temperature Winkler (HTW) gasification technology. The costs for syngas cleaning are significantly reduced by an innovative acid gas removal stage for the subsequent synthesis step.
The work programme starts with lab scale investigations regarding the feedstock properties relevant for fluidized bed gasification and the development of the acid gas removal stage. Then, the full process chain is tested at real conditions in a pilot plant with a size of 0.5 MWth feedstock input. The process is scaled up to industrial size using adequate models that have been validated at pilot scale. Finally, a techno-economic assessment and life cycle analysis is performed.
The results of this project will be used by the project partners to evaluate the ecomomics of the concept and to assess the feasibilty of a future demonstation plant.
