Mixing of Fast Pyrolysis Oil and Black Liquor : Preparing an Improved Gasification Feedstock
Co-gasification of fast pyrolysis oil and black liquor can be used to increase the size and improve profitability of pulp mill integrated biorefineries. The acids present in pyrolysis oil limit the amount that can be mixed into black liquor without causing precipitation of the black liquor dissolved...
