微波强化NiO/Al2O3催化城市生活垃圾气化及焦油降解机理研究
Study on microwave-enhanced catalytic gasification of municipal solid waste and tar degradation mechanism over NiO/Al2O3
摘要
Abstract
To address the challenges of high tar yield,low tar degradability,and catalyst deactivation caused by carbon deposition during municipal solid waste(MSW)gasification,a novel strategy integrating microwave induction with catalytic reforming was proposed to enhance the selective degradation and conversion of refractory tar.NiO/Al2O3 was employed as the catalyst to investigate the gasification characteristics,product distribution,and compositional evolution of MSW under microwave-assisted conditions.The results demonstrated that gasification temperature exerted a significant influence on product distribution.As the gasification temperature increased,the yield of pyrolysis gas increased markedly,whereas the yields of char and tar decreased correspondingly.In addition,increasing the NiO loading led to a gradual reduction in tar yield,accompanied by continuous improvements in total gas yield,carbon conversion efficiency,and gasification efficiency.At a NiO loading of 15％,the tar yield decreased to 10％,while the pyrolysis gas yield reached 68％.Under these conditions,the total gas yield,carbon conversion efficiency,and gasification efficiency achieved 0.882 m3/kg,90％,and 94.2％,respectively.Compared with conventional gasification,microwave-assisted gasification promoted localized high-temperature reactions on the catalyst surface and effectively suppressed carbon deposition,thereby enhancing catalyst stability and prolonging catalyst lifetime.关键词
