Hot Gas Cleaning of Biomass Derived Syngas by Catalytic Filter Candles

C. Varga, S. Koppatz, C. Pfeifer & H. Hofbauer
Biomass derived syngas is widely expected to establish the local energy supply. The context comprises syngas utilisation via dual fluidized bed gasification to heat and power generation and moreover the conversion into synthetic natural gas, liquid fuels or chemicals. Essential requirement for the application and further conversion processes is the syngas purity. The syngas purification focuses on gaseous and solid impurities, whereas mainly tars and particles (ash, coke, attrition of bed material) are addressed, which...
