氧化物催化剂对非热等离子体催化降解甲苯的影响
Impact of oxide catalysts on toluene destruction by non-thermal plasma
摘要
Abstract
The effects of different oxide catalysts on NTP catalytic decomposition toluene in dry atmosphere were investigated in this work.For different catalysts,the decomposition efficiency of toluene,carbon balance,CO2 selectivity and O3 removal were studied through the dielectric property,surface oxygen delivery capacity,specific surface area and pore structure,respectively.The results show that the decomposition efficiency of toluene,carbon balance and the outlet concentration of O3 can be improved by the dielectric property.However,the dielectric property doesn' t affect the CO2 selectivity and O3 removal at all.For a given specific energy density,the effect of specific surface area and pore structure on the CO2 selectivity and O3 removal is more significant than dielectric property.Additionally,the surface oxygen delivery capacity of the catalysts could promote obviously the decomposition reaction of toluene,and the influence is stronger than specific surface area and pore structure.关键词
