摘要: 针对中国石油化工集团有限公司开发的以餐饮废油为原料生产生物质喷气燃料(简称生物喷气燃料)两段加氢(SRJET)技术,基于生命周期的评价分析,确定核算边界,分析了生物喷气燃料生命周期碳足迹(单位产品生命周期过程中所导致的直接和间接的CO2排放总量)。通过对比生物喷气燃料与石油基喷气燃料的生命周期碳足迹评价了生物喷气燃料替代石油基喷气燃料的碳减排效果,通过不确定性分析及各环节参数因子敏感性分析,明确了生命周期模型参数对碳足迹评价的影响水平。结果表明,生物喷气燃料的生命周期碳足迹总量为0.55 kg/kg,在模型预测结果90%置信区间内,相比于石油基喷气燃料,生物喷气燃料生命周期碳排放总量(以CO2计)降低80.9%~93.2%。生物质喷气燃料技术推广和产业链构建对助力我国“碳达峰、碳中和”战略目标实现具有重要意义。

Abstract: Aiming at the two-stage hydrogenation technology(SRJET) developed by SINOPEC to produce biomass jet fuel (bio jet fuel for short) from waste catering oil, basing on the life cycle assessment analysis, the accounting boundary was determined, and the carbon footprint of the life cycle of bio jet fuel (total direct and indirect CO2 emissions per unit of product lifecycle) was analyzed. The carbon emission reduction of bio-jet fuel replacing petroleum-based jet fuel was evaluated by comparing of the life-cycle carbon emissions. The results showed that the total carbon emission during the life cycle of producing 1 kg bio-jet fuel was 0.55 kg, and within the 90% confidence interval of the prediction result, the CO2 emission of bio-jet fuel was 80.9%-93.2% lower than that of petroleum-based jet fuel. The promotion of bio-jet fuel is of great significance to achieve the strategic goal of emission peak and carbon neutrality.
