摘要
以流化床快速热裂解制取生物油系统为研究对象,确立系统边界,对其进行全生命周期评估,讨论整个系统在全生命周期中的能耗、全球变暖潜值、酸化潜能及其他环境影响潜值。计算得到系统制取生物油在生命周期中的净能量值为0.68 MJ/MJ,全球变暖潜值为0.0565 CO2-Equiv.kg/MJ,与其他液体燃料相比更具环境友好性;对环境影响潜值进行标准化和加权结果计算,全面显示系统不同部分对环境的影响。
The life cycle assessment of a fast pyrolysis scenario for bio-oil production was conducted to evaluate whether the process would be environmentally friendly. The net energy value （NEV）, energy consumption, global warming potential （GWP）, acidification potential （AP） and some other environmental impact values in the life-cycle stage of biomass fast pyrolysis system were discussed. The net energy value was 0.68 MJ/MJ, and global warming potential was 0.0565 CO2-Equiv.kg/MJ. The normalization and weighting results of these environmental impact values were analyzed to investigate the impact distribution of in the different stages of life cycle of biomass fast pyrolysis. The results show that the biomass fast pyrolysis technology is environmentally friendly and hopefully, and can make positive contribution to climate change and environmental pollution problems.
