The potential GHGs reduction of co-processing aviation biofuel in life cycle

Abstract The challenge of drop-in jet biofuel should couple the reduction GHGs emission in whole life cycle with economic competitiveness and achieving performance without reducing engine aircraft. Co-processing was recognized a promising solution due to availability existing refining infrastructure facilities. Based on LCA approach, quantitative assessment model (AF-3E) has been established for discovering potential by co-processing. Typical representatives oily feedstock, including used cooking oil, soybean, rapeseed, peanut, corn Xanthoceras sorbifolia, jatropha algae, were compared co-processing HEFA-SPK blend energy consumption life. Computational framework is integrated into 3 sub-models 4 modules, which include feedstocks model, fuel flight electricity module, hydrogen methanol hexane module. In emissions investigated at LTO condition cruise transfer six types typical aircraft widely similarity criterion. achieve less than blend, attributed stage. Used oil conducts 8.17% 5% bio-feedstock 6.39% petroleum-based fuel. By sensitivity analysis, vital factors have extracted cycle. purpose this paper discover advantages results would enhance interests both sustainable aviation biofuel. Graphical
