- Wood to mixed alcohols,
- Refuse derived fuel (RDF) to mixed alcohols,
- Wood to FT distillate,
- RDF to FT distillate, and
- Natural gas to mixed alcohols.
The new pathways are fully integrated into GHGenius, for each fuel cycle the fuel is used for both light duty and heavy duty applications. All of the existing functionality of the model has been retained.
This work has involved the development of a new feedstock, RDF. This material is produced by collecting, separating and in some cases processing municipal solid waste (MSW). The user can now specify all of the key parameters, collection distances, processing energy, and material yield for collecting and converting MSW to RDF.
A new fuel, mixed alcohols has been added to the model. This fuel is a mixture of C1 to C5 alcohols and the user can specify the mixture of alcohols consistent with the rest of the inputs. This fuel could be used in low level blends with gasoline or diesel fuel or as a fuel itself in large heavy-duty engines. All of these applications have been added to the model.
While the primary interest in the mixed alcohols is for their production from the renewable feedstocks, wood and RDF, a pathway to produce the mixed alcohols from natural gas has been added for comparison.
It is also feasible to produce FT Distillate from wood or RDF rather than from natural gas and these are the fourth and fifth pathways added to the model, The FT Distillate is used in heavy-duty engines either alone or in a blend with conventional diesel fuel. The production of FT Distillate from natural gas was already in the model for comparison.
