The co-cracking of vacuum gas oil (VGO) and bio-oil has been proposed to add renewable carbon into the co-processing products. However, the environmental performance of the co-processing scheme is still unclear. In this paper, the environmental impacts of the co-processing scheme are calculated by the end-point method Eco-indicator 99 based on the data from actual industrial operations and reports. Three scenarios, namely fast pyrolysis scenario, catalytic pyrolysis scenario and pure VGO scenario, for two cases with different FCC capacities and bio-oil co-processing ratios are proposed to present a comprehensive comparison on the environmental impacts of the co-processing scheme. In Case 1, the total environmental impact for the fast pyrolysis scenario is 1.14% less than that for the catalytic pyrolysis scenario while it is only 26.1% of the total impacts of the pure VGO scenario. In Case 2, the environmental impact of the fast pyrolysis scenario is 0.07% more than that of the catalytic pyrolysis and only 64.4% of the pure VGO scenario impacts. Therefore, the environmental impacts can be dramatically reduced by adding bio-oil as the FCC co-feed oil, and the optimal bio-oil production technology is strongly affected by FCC capacity and bio-oil co-processing ratio.

现有炼油厂中生物油和真空瓦斯油共处理的比较生命周期评估
已提出真空瓦斯油(VGO)和生物油的共裂化工艺将可再生碳添加到共处理产品中。但是,协同处理方案的环境性能仍然不清楚。在本文中,协同处理方案的环境影响是通过端点方法Eco-indicator 99根据实际工业操作和报告中的数据计算得出的。针对两种FCC容量和生物油协同处理比例不同的情况,提出了三种快速分解方案,催化热分解方案和纯VGO方案,以对协同处理方案的环境影响进行全面比较。在案例1中,快速热解方案的总环境影响比催化热解方案的总环境影响小1.14%,而仅为26。纯VGO方案总影响的1%。在案例2中,快速热解方案的环境影响比催化热解方案的环境影响高0.07%,而纯VGO方案的影响仅为64.4%。因此,通过添加生物油作为FCC共同进料油,可以大大减少对环境的影响,而最优的生物油生产技术受FCC容量和生物油共处理比例的强烈影响。
