(738b) Effect of Feedstock and Pyrolysis Method on the Yield of Hydrotreated Refinery Intermediate
Therefore Idaho National Laboratory (INL), the National Renewable Energy Laboratory (NREL), and Pacific Northwest National Laboratory (PNNL) have been collaborating to study the effect of feedstock properties and vapor-phase upgrading (VPU) on the yield and quality of the hydrotreated products. INL has provided feedstocks, NREL has performed pyrolysis/VPU, and PNNL has hydrotreated the liquids. Preliminary results suggest that air classified forest residue is a promising low-cost waste stream and miscanthus is a promising energy crop for these processes. Modeling has identified lignin, volatile matter, and alkali content of the biomass as key predictors of pyrolysis yield.
Ongoing work is exploring the effect of the type of lignin and modeling the effect of oil properties on the hydrotreating.
