Keywords: Biomass gasification; EPR analysis; Particulate matter; XRF

Abstract: The present work aims at characterizing particulate matter (PM) of different size, emitted during biomass gasification in a drop tube furnace (DTF) at 1000 °C. The elemental composition was determined using X-ray fluorescence (XRF) and Electron Paramagnetic Resonance (EPR) analyses. Overall 19 elements were determined and the relative mass concentration of their oxides was identified as macro- (above 3%) and micro-concentration (below 3%). The elements Fe, Mn and S were found in each type of particulates, regardless of the used biomass and gasifying agent. The dominant macro component of char (cyclone particles >10 µm) was Ca (50.56–100% of the total CaO), followed by K, Fe, S, Mn and Cr. Only colza char contained significant portion of P and much lower Fe. The primary macro constituents of PM10–2.5 were Fe, Mn and S. The volatile ash compounds K and Cl are typical constituents of the submicron sized ultrafine particles (UFP), when biomass from agricultural residue was gasified.
