Abstract: Catalytic cracking of biomass tar was investigated using steam gasification obtained char supported nickel catalyst in a lab-scale fixed bed reactor to determine the effects of catalytic cracking temperature, Ni loading and gas residence time on product distribution and gas composition. Results showed that the optimum catalytic cracking parameters were at 800 °C catalytic cracking temperature, 6 wt% Ni loading and 0.5 s gas residence time. The characterizations of tars were determined by ultimate analysis, FTIR and GC-MS. Compared with no catalyst cracking, the relative content of single-ring aromatics in tars obviously increases with the appreciably decreases in polycyclic aromatics, O-containing compounds and heterocyclic compounds after catalytic cracking, especially in Ni-6/char catalyst condition.
