One of the major obstacles for the application of biomass gasification systems is the relatively high tar content of the producer gas that inhibits its use in engines or turbines or in catalytic processes like in methanisation or Fischer-Tropsch synthesis without further gas cleaning. The determination of the tar content with conventional methods is very time consuming and does not allow a continuous online monitoring of the gas quality. The approach, to avoid these drawbacks,...
