The Nagaoka Garbage Bio Gasification Business (PFI)

Summary of the five PFI reports

Observations on Pfi Evaluation Criteria

In light of the NSF’s commitment to measuring performance and results, there was strong support for undertaking a proper evaluation of the PFI program. The preceding chapters reported on a number of specific outcome measures and process measures (signposts) that were suggested to assess program performance; we now turn to some of the broader principles that were articulated (or could be inferre...

Development and application of numerical models for simulating bio-oil gasification

Bio-oil, a mixture of complex oxygenated hydrocarbons, is obtained through fast pyrolysis of solid biomass. As biomass is low in energy density and not easily transportable, a novel approach is to convert biomass to bio-oil, transport bio-oil to a centralized facility, gasify bio-oil to syngas, and upgrade syngas to transportation fuels and other high-value chemicals. In this study, a comprehen...

Supply chain design under uncertainty for advanced biofuel production based on bio-oil gasification

An advanced biofuels supply chain is proposed to reduce biomass transportation costs and take advantage of the economics of scale for a gasification facility. In this supply chain, biomass is converted to bio-oil at widely distributed small-scale fast pyrolysis plants, and after bio-oil gasification, the syngas is upgraded to transportation fuels at a centralized biorefinery. A two-stage stocha...

Techno-economic analysis of advanced biofuel production based on bio-oil gasification.

This paper evaluates the economic feasibility of an integrated production pathway combining fast pyrolysis and bio-oil gasification. The conversion process is simulated with Aspen Plus® for a 2000 metric ton per day facility. Techno-economic analysis of this integrated pathway has been conducted. A total capital investment of $510 million has been estimated and the minimum fuel selling price (M...
