Carbon Cycle in Bioethanol Production

Shortening the carbon cycle!

Fuel Properties Summary

Goal:

Qualify C2 alcohol (ethanol) as starting material to

produce Synthetic Paraffinic Kerosenes for Jet Fuel

in Aviation Turbines

Currently only C4 alcohol (isobutanol) allowed in

Annex A5, Alcohol-to-Jet Synthetic Paraffinic

Kerosene (ATJ-SPK) of ASTM D7566

Completed

LanzaTech Research Report on Ethanol Based ATJ-SPK Submitted September 2016

Step 3 Positive OEM feedback received – no Tier 3 or 4 testing required

Addressed OEM Feedback

Updated Report for Step 7 OEM Review September 2017

Ballot Status

ASTM Ballot to incorporate ethanol based ATJ-SPK in Annex A5 D7566

Ballot Passed Aviation Fuel J ASTM Subcommittee November 9th 2017

US Department of Energy providing up to 50% of project costs for

first demonstration of industrial off-gas to sustainable aviation fuel

Demonstrate conversion of ethanol from multiple sustainable feedstocks into low carbon aviation fuel

Develop process and operational parameters for commercial alcohol-to-jet units

Produce sufficient jet fuel for multiple commercial flights per week

Phase 1 – develop full engineering and business package (2017 – 2018)

Phase 2 – construct, commission, operate and produce fuel (2018 – 2020)
