Abstract: This paper has studied characteristics of mixed Catalyst Used for Biomass catalytic cracking. The experiments was taken on the home-made two-stage fixed bed pyrolysis reactor, with the pyrolysis temperature at 700℃，and the cracking temperature from 700 to 950℃.Sawdust was used as biomass raw material.N2 and steam were used as carrier gas respectively. The obtained results showed that the catalyst had excellent low temperature catalytic properties. When the cracking temperature was 750℃,the tar conversion rate of the biomass gas reached more than 95%,and the gas yield rate increased by 65% compared with non-cataltic situation. When the cracking temperature was held at 950℃，the tar conversion rate reached 99.5%, gas production rate increased 1.3 times. The concentration of H2 reached 59.5%, increasing 1.82 times than before; concentration of CH4 was reduced to 3.8%, dropping 60%.The catalyst also has strong anti-aging properties and good reproducibility.
