Steady-state process simulation and techno-economic analysis: Uncatalyzed fast pyrolysis to hydrocarbons and related conversion simulations 

The Pacific Northwest National Laboratory (PNNL) team has prepared techno-economic (TEA) studies for various fuels and chemicals from biomass, coal and natural gas using scales from bench to commercial sizes. These studies include efforts to model experimental work and track research progress for uncatalyzed fast pyrolysis to hydrocarbons.

These TEAs provide information related to the effects of feedstock variations (ash and moisture content, for example) that FCIC researchers will leverage for the FCIC project. Reduced-form cost and performance models have been developed for other projects and that knowledge will be used to develop linkages to the DES model.

The National Renewable Energy Laboratory (NREL) team has worked on the TEA of biomass catalytic fast pyrolysis (CFP) processes for fuels and chemicals production. After initial efforts to streamline the analysis using the uncatalyzed fast pyrolysis pathway, additional efforts will also include the study of CFP routes and associated feedstock-related impacts on those processes. With information from related experimental efforts, the steady state CFP models will be used to inform the conversion metrics and associated linkages with the larger DES model.
