Following are the conversion pathways for sustainable bio-jet fuel production.(Serial 1-4 are ASTM certified)
1.Hydro- processed Esters and Fatty (HEFA)
2. Fischer-Tropsch (FT)
3.Direct sugars to hydro carbon (DSHC)
4.Alcohol to jet (ATJ)
5. Pyrolysis
6. Hydrothermal Liquefaction
In order to make a business case we must link conversion techniques with the feed-stock (2nd Gen.)
Literature focuses on any one type of feed-stock. For example in agriculture waste, wheat straw would be considered for Gassfication and FT, but it can also be considered for Alcohol to jet or Direct sugars to hydrocarbon.
Here is my categorization:
1. HEFA-Algae and non-edible oil seeds
2. For all other pathways MSW, Forestry residue, agriculture waste, wood waste.
