... is extended to show how the composition of the production chemical changes as the oil/water ratio changes. The results show that the composition of the original production chemical in either the oil or water phases is rarely the same as the neat product on injection and can vary substantially as the water-cut...

... the fast pyrolysis process. Following some characterization of the bio- oils at NREL, the bio-oils were shipped to Oak Ridge National Laboratory (ORNL) for corrosion testing and further characterization. The content and composition of ash in each bio-oil was determined. Corrosion testing consisted...
