Characterization of Tar Generated during Updraft Gasification of Woody Biomass in Auto-thermal Packed Bed Reactor

Abstract

This study presents characteristics of tar formed during updraft gasification of biomass by using mass spectrometry and thermogravimetric analysis. Tar content in producer gas is higher at the lower-middle part of the reactor which represents a pyrolytic zone. Tar is composed of C, H, N and O by 70.62%, 10.62%, 0.57% and 18.20%, correspondingly and its HHV is around 35.27 MJkg -1 . ToF-MS analysis for ion mass-to-charge ratio ( mz
