摘　　要：报道了乙烯生产的生命周期清单分析方法,并得到清单的计算结果:单位量乙烯生产相关原煤、原油和天然气的生命周期消耗量分别为85.60kg/t、2302.56kg/t和162.21m3/t,相关CO2、SO2、NOx、CO、乙烯和烟尘的生命周期排放量分别为2257.04kg/t、8.93kg/t、11.60kg/t、7.62kg/t、2.90kg/t和5.84kg/t。研究结果表明,乙烯、CO、烟尘和NOx生命周期排放的主要来源为乙烯生产的直接排放,CO2的直接排放和间接排放基本相当,SO2的生命周期排放则主要来源于燃料的生产与加工阶段。The method for developing life cycle inventory of ethylene production was introduced, and the life cycle inventory was compiled. The life cycle consumptions of raw coal, crude oil and natural gas of unit ethylene production were 85.60 kg/t, 2302.56 kg/t and 162.21 m^3/t respectively, and the life cycle emissions of CO2, SO2, NOx, CO, ethylene and dust were 2 257.04 kg/t, 8.93 kg/t, 11.60 kg/t, 7.62 kg/t, 2.90 .kg/t and 5.84 kg/t respectively. The direct emissions of ethylene production was the main source of the life cycle emissi,n of ethylene, CO, dust and NOx. The CO2 direct emission and indirect emission was equivalent with each other basically; while the life cycle emission of SO2 mainly came from the stages of fuels production and transportation.
