| 摘 要： | 对以餐饮废弃油脂为原料,利用化学催化法生产的生物柴油进行了生命周期能耗与CO2排放分析,以具有1 MJ能量的生物柴油产品为功能单位.结果表明:生物柴油生命周期总能耗为1.648 9 MJ,化石能耗为0.616 9 MJ,化石能效比为1.62,生命周期净能量产出为0.383 1 MJ,生命周期CO2净排放量为-10.34 g.与生产和使用1 MJ能量的石化柴油相比,生物柴油生命周期总能耗升高37%,化石能耗降低49%,可减少CO2排放90.99 g.

| Abstract: | Life cycle energy consumption and CO_2 emission analysis of bio-diesel made from food waste oil using chemical catalysis method were conducted.Bio-diesel product with energy content of 1 MJ was taken as the functional unit.Results indicated that life cycle total energy consumption of bio-diesel was 1.6489 MJ,life cycle fossil energy consumption was 0.6169 MJ,fossil energy efficiency ratio was 1.62,life cycle net energy was 0.3831 MJ,and life cycle net CO_2 emission was -10.34 g.Compared with petrochemical diesel with equal energy,the life cycle total energy consumption of bio-diesel made from food waste oil using chemical catalysis method increased by 37%,life cycle fossil energy consumption reduced by 49%,and 90.99 g CO_2 emission could be reduced. |
