In Part 1 of this article, economic incentives were estimated for relaxing the requirement that biocrude entering the refinery infrastructure be oxygen (O2)-free. It was concluded that an accurate estimate of these incentives is not possible without a significant amount of additional data. Part 2 examines key issues that must be addressed and the associated data needed for this constraint to be relaxed.
In Part 1 of this article, the incentives and information needed to relax the constraints of being O2-free are outlined. The authors hope that this perspective provides new directions for improving the economics of using pyoil to produce advanced biofuels (ABFs).
