Description: Das Projekt "Energieforschung (e!MISSION), EnCat: Enhanced catalytic fast pyrolysis of biomass for maximum production of high-quality biofuels" wird/wurde gefördert durch: Österreichische Forschungsförderungsgesellschaft mbH (FFG). Es wird/wurde ausgeführt durch: Bios Bioenergiesysteme GmbH.Fast pyrolysis of biomass is one of the most promising ways to directly generate liquid fuels from biomass. However, the produced pyrolysis oil may have several major drawbacks which suppress its application for power and heat generation or transportation fuels, such as high oxygen, water and water-soluble (acids) contents, miscibility with petroleum-based fuels, chemical stability, high viscosity and low energy densities. The Enhanced Catalytic Pyrolysis (EnCat) project aims at the development of a new concept for the production of high-quality bio-oil at a high yield. Because of a novel biomass pre-treatment step to be developed the concept shall be suitable for both woody biomass and biomass residues from agriculture. The pre-treated biomass shall be pyrolysed in a reactor making use of deoxygenation catalysts. Simultaneously, CO2 shall be captured with sorbents and via the water-gas-shift reaction in-situ hydrogen shall be produced. After cleaning, the oil vapours shall be mildly hydrogenated to produce a high-quality bio-oil. The high-quality oil shall be used for combustion tests in both a diesel engine and a gas turbine for combined power and heat generation. Parallel to this, the bio-oil shall be further upgraded by a new method of downstream hydrogenation under high pressure for production of high-grade transportation fuels. At the end of the project, a full-scale design concept for the new process shall be available. In order to assure also an economically and environmentally feasible process development, accompanying techno-economic analyses, environmental impact assessments and LCAs shall be performed. Within the framework of the international project, the Austrian partner BIOS shall develop a new biomass pre-treatment process based on leaching with the light (water-rich) fraction of the pyrolysis oil. By this measure the contents of ash forming matter shall be reduced significantly and thereby the suitability of the feedstock for pyrolysis shall be improved. Therefore, systematic lab-scale leaching test with both, simulated wood-derived acids and real light fractions from pyrolysis shall be performed at different temperatures, residence times, acidities and fuel/leaching agent ratios. The process shall be optimised in terms of technological, economic and environmental aspects. The treatment of the waste water (leachate) shall thereby also play a relevant role. As a second main task, BIOS shall contribute to the further development of a gas turbine for the utilisation of bio-oil with numerical (CFD) simulations. The main objective shall be to develop a turbine combustion chamber design and air staging concept for complete burnout and operation at low NOx emissions. To make the turbine better suitable for decentralised (heat controlled) applications, partial load operation capability shall thereby be a relevant development target. (abridged text)
