MODEL-BUILDING AND OPTIMIZATION FOR EXTRICATION PROCESS OF TAR PRODUCED IN GASIFICATION BY USING CATALYTIC CRACKING

Through analysis of factors affecting the catalytic cracking rate of tar produced in the process of biomass gasification,an optimizing model for extrication process of tar produced in rice straw gasifi-cation by using catalytic cracking has been established on the basis of least square supporting vector machine (SVM),and the validation being carried out. On this basis,a parameter optimizing calculation for the extrication process of tar by using catalytic cracking has been made, results show that the said model has better generalization ability and fitting effect, it can efficiently simulate the extrication process of tar produced in biomass gasification by using catalytic cracking.
