<p>In a dual fluidized bed gasifier, steam is used as a gasifying agent for gasifying a fuel. The amount of steam may be changed by the gasifier’s operating conditions. The characteristics of the tar components by the change of supplied steam in the gasifier are very important in the design of the tar treatment of the gasification system. In this study, the behavior of tar components in a practical steam gasification conditions of lignite were clarified. A gasification experiment was conducted by changing the amount of steam at 1123 K using a laboratory-scale fluidized bed gasifier. As the results, by an analytical method combining gas chromatograph mass spectrometry and the field desorption mass spectrometry, the main component of tar was found to be polycyclic aromatic hydrocarbons, independent of the change of supplied steam in the gasifier.</p>
