Description:
A life cycle assessment has been done on various gasoline blends, The purpose of this study is to compare several gasoline blends of 95 and 98 octaine, that meet the vapour pressure upper limit requirement of 60 kPa. This study accounts for the gasoline losses due to evaporation and leaks, from petroleum refining to vehicle refuelling, and evaluates the potential environmental impacts (PEI) using the Waste Reduction (WAR) algorithm. The results indicate that for lower PEI it is better to use less reformate in gasoliine, due to its high contribution to the photochemical ozone creation potential. This study also shows that the life cycle stage with the largest contribution to the PEI is gasoline production at the refinery.
