Technoeconomic Sensitivity Of Biobased Hydrocarbon Production Via Fast Pyrolysis To Government Incentive Programs, Tristan Brown, Guiping Hu Jun 2012

Technoeconomic Sensitivity Of Biobased Hydrocarbon Production Via Fast Pyrolysis To Government Incentive Programs, Tristan Brown, Guiping Hu

Fast pyrolysis and upgrading is a promising thermochemical pathway that produces pyrolysis oil that can be upgraded via hydroprocessing into hydrocarbon-based transportation fuels (drop-in biofuels). The internal rate of return (IRR) of a fast pyrolysis and upgrading facility is a function of feedstock cost and projected revenues. We calculate the IRR of a fast pyrolysis and upgrading facility under six different policy scenarios: (1)a baseline scenario in which the facility receives no government support; (2)a scenario in which cap-and-trade (H.R. 2454) is enacted with both carbon price and offsets; (3)a scenario in which the Volumetric Ethanol ...

We evaluate the economic feasibility of a fast pyrolysis facility producing biobased commodity chemicals based on various manifestations of Integrated Catalytic Processing (ICP). Five scenarios are analyzed: fluid catalytic cracking (FCC) of whole pyrolysis oil (WPO); one-stage hydrotreating and FCC of WPO; FCC of the aqueous phase of pyrolysis oil (APPO); one-stage hydrotreating and FCC of the APPO; and two-stage hydrotreating followed by FCC of the APPO.

We calculate the internal rate of return (IRR) for each scenario as functions of the costs of feedstock, hydrogen, and catalyst, and projected revenues for the facility. The assumed feedstock cost is $83 ...
