• The tar produced in the biomass gasification process had a bad effect on the whole gasification process flow. If the tar can be transformed into combustible gas before condensation, the gasification efficiency would be improved and the tar content would be decreased. This thesis built a tar catalytic cracking and removal process model of biomass rice straw pyrogenation and gasification by based on the analysis of factors influencing the tar catalytic cracking rate, and least squares support vector machine, and conducted the validation. On this basis, this thesis did an optimized calculation upon the parameters of the tar removal process. The results proved that this model had good generalization ability, fitting effect, and can simulate the characteristics of biomass rice straw catalytic `cracking process, and when the catalytic cracking temperature reached 937.0101℃ and the gas residence time was 0.9041 s, the maximum of the tar catalytic cracking rate can be 95.4418%.
