1 Innovative Process Technology for Refining Lignite R&D needs IBI Innovative Braunkohlen Integration in Mitteldeutschland (Innovative Lignite Integration in Middle Gemany) 17 th European Round Table on Coal Horizon 2020: best use of fossil fuels Brussels, June 6 th 2012 Prof. Mathias Seitz page: 1

2 Topics Opportunities for Refining Lignite - Stable price for lignite - Increasing national added value in Europe - Using carbon footprint method, lignite seems to be better than natural gas with regard to CO 2 equivalents - Value chains show higher efficiency than one technique alone - The conversion of lignite to chemicals enables reasonable integration of renewables Needs - Development of value chains with new technologies - Chemical parks as technology bases for testing (demonstration plants) - Guaranty in planning page: 2

3 In the Long Term only Lignite will be a price stable and available Feedstock Price in % Basis year 2000 Oil (crude + fuel) Natural gas Coal (import) Lignite (briquette + dust) Ref.: page: 3

12 The use of lignite for chemicals enables the integration of renewable energies! The use of lignite produces CO 2. Renewable energies show different capacities (wind, solar). How can excess energy be used? How can a lack of energy be balanced out? Examples: 1.) Inverse SOFC: Production of H 2 /CO from CO 2 and H 2 O Integration in methanol production Syngas chain and chemical usage is necessary 2.) Electrolysis of H 2 O: H 2 use for hydrogenation reactions e.g. aromatics to cycloalkanes 3.) Combined cycle produces electrical power if renewables are weak or it produces syngas in the case of a low electrical power demand Syngas chain and chemical usage is necessary page: 12
