生物质气化焦油催化裂解脱除过程的建模与优化

摘要

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.%通过对生物质气化过程中影响焦油催化裂解率因素的分析,依据最小二乘支持向量机建立了稻秆气化焦油催化裂解脱除过程的优化模型,并进行了验证,在此基础上对焦油催化裂解脱除过程做了参数优化计算.结果表明,该模型具有较好的泛化能力和拟合效果,可有效地模拟生物质气化焦油催化裂解脱除过程.
