A major problem in the current biomass gasification systems is the formation of tar. The condensed tar at low temperatures may cause blockage and pollution of downstream equipments, as well as environmental pollution. Therefore, the removal and conversion of tar are the key issues for biomass gasification. At present, the common methods of tar removal are mainly mechanism methods, thermal cracking and catalytic cracking. In this paper, the catalytic cracking method and its advantages and disadvantages are discussed.
