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