摘　　要：应用水吸收-催化燃烧技术处理PET聚酯生产中排放的含乙二醇、2-甲基-1,3-二氧戊环、乙醛等废气。水吸收可以有效脱除高沸点的乙二醇,通过对乙醛的吸收、解吸作用使废气的总烃浓度得到均匀化处理;采用Pt/Pd/CeO_2蜂窝状催化剂,在反应器床层空速40 000h^(-1),入口温度250℃,入口总烃浓度3 522～5 666μL/L的条件下,反应器出口总烃浓度54～84μL/L,乙醛浓度3～11μL/L,总烃去除率达到97.6％～98.9％,净化后气体符合国家排放标准。A water absorption and catalytic combustion process was used to treat PET polyester waste gas containing ethylene glycol, 2-methyl-1 ,3-dioxolane and acetic aldehyde. Water absorption could effectively remove high boiling point ethylene glycol, and equilibrate total hydrocarbons concentration by absorption and stripping of acetic aldehyde. When a Pt/Pd/CeO2 honeycomb catalyst was used with gas space velocity of 40000h-1 , inlet temperature of 250℃ and inlet total hydrocarbon concentration of 3 522 - 5 666μL/L, outlet total hydrocarbon concentration was reduced to 54 - 84μL/L, outlet acetic aldehyde was reduced to 3 - 11μL/L; i. e. , total hydrocarbon removal could reach 97. 6% -98. 9%, and the cleaned gas could meet the national exhaust specification.
