In order to study the effect of catalytic conversion of biomass gasification tar model compound (toluene) by oak char, a fixed bed test system was used to test the conversion efficiency of toluene, the liquid phase composition was detected by GC-MS. The results show that the conversion efficiency of toluene does not exceed 57.27% at 600 and 700 Â°C, but it increases significantly at 800 Â°C, up to 93.07% of KMnO4 modified char. The content of the liquid phase product of the catalytic conversion of toluene is related to the temperature and whether the char is modified. Moreover, most of liquid phase product are aromatic compounds. Among them, bibenzyl is an important intermediate product in the catalytic conversion of toluene.
