In-situ Chemical Hot Gas Cleaning in Fluidized Bed Steam Gasification of Biomass

M. Stemmler & M. Müller
The “UNIQUE” project aims at a compact version of a biomass gasifier by integrating the fluidized bed steam gasification and the hot gas cleaning as well as the conditioning system into one reactor vessel. This work verifies the suitability of chemical hot gas cleaning depending on the demands of the catalytic filter candle and the fuel cell. The main focus was laid on alkali removal and sour gas control, as these can cause filter plugging...
