The utilization of tar in the process of biomass gasification reburning was investigated. The tar components released during the pyrolysis and gasification of typical agricultural wastes were analyzed on the TG-MS (thermogravimetry and mass spectrometry) system. And the effect of tar on the NO reduction by biomass gasification syngas was studied on a flow reaction system, as well as the effect of the parameters such as bulk equivalence ratio and temperature. Finally, the model of NO reduction by toluene was built, and verified by the results from the stop-flow reaction system. The results show that benzene, toluene, styrene and phenol are typical components of tar. Tar has a positive influence on the NO reduction by biomass syngas, and there's a suitable environment, including bulk equivalence ratio, temperature and so on, that makes the reduction most efficient. The polymerization should be concerned. The NRT (NO reduction by toluene) model simulates the experimental results well, and HCCO and C2H seem to be important to the NO reduction.
