Commercialization of pyrolysis oil in existing refineries—Part 2

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.

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. Knowns and unknowns at the biocrude-refinery interface In considering a feedstock as radically different as pyrolysis oil (pyoil), the refiner is faced with several unattractive knowns and a large number of unknowns. These factors represent potentially serious threats to smooth refinery ope
