摘要：

采用混合生命周期法,将生命周期框架与经济投入产出生命周期评价相结合,全面考虑农业机械生产、厂房建设、设备安装、固废处理过程及保险业的间接温室气体排放量,对玉米秸秆热解加氢提质得到的精制油进行生命周期温室气体排放量核算.结果表明：整个过程中温室气体排放量为45.2 g /MJ (折算成克CO2 当量),直接排放122.02 g /MJ,间接排放46.4 g /MJ,光合作用抵扣101.68 g /MJ；氮肥投入、种子投入和电力投入为三大主要排放因素;肥料生产制造业、电力生产供应业、谷物生产业三大部门占间接排放总量的86%.分析整个过程温室气体排放量的不确定因素可知：玉米秸秆产量影响最大,产油率次之,运输距离最小.与木薯乙醇和传统汽油相比,精制油生产过程温室气体排放量分别减少53.0%、51.9%.
Abstract:

 A hybrid life cycle method, combining the life cycle framework with economic input output life cycle assessment, was used to calculate the life cycle greenhouse gas emissions of corn stalk pyrolysis and hydrogenation upgrading. The effect of indirect greenhouse gas emissions of agricultural machinery production, plant construction, equipment installation, solid waste treatment process and the insurance industry was considered. Results showed that the greenhouse gas emissions of the whole process was 45.2 g /MJ, the direct emissions was 122.02 g /MJ, indirect emissions was 46.4 g/MJ and offset of photosynthesis was 101.68 g/MJ. Three major emissions came from N fertilizer, seed and electricity. The fertilizer manufacturing industry, electric power production and supply industry and grain production industry were the major department with largest indirect emissions, which accounted for 86% of the indirect emissions. The analysis of uncertain factors in the whole process demonstrated that corn straw yield impacted most significantly following with oil production rate and the transport distance was the last. The greenhouse gas emissions of oil refining production process reduced 53.0% and 51.9% compared with cassava based ethanol and traditional gasoline.
