FUTURE-PROOF YOURETHANOL PRODUCTION.
Transition To Sustainable Aviation Fuel…Profitably.
FLEXIFORMING® FOR ETHANOL PLANTS
by Universal Fuel Technologies

Low-cost, carbon-efficient, and 100% drop-in
Sustainable Aviation Fuel for ethanol producers

The Future of Ethanol is Aviation.

ARE YOU READY TO TAKEADVANTAGE OF THE TRANSITION?
Flexiforming® is the most cost-effective andflexible pathway to enter the SAF market.

1LOWERUTILITY AND
HYDROGEN
COSTS

Flexiforming’s integrated process design reduces
energy consumption by up to 75%

Key chemical reactions of Flexiforming occur in the same vessel, with no gaseousintermediate products to compress or refrigerate. Flexiforming SAF includes aromatics indesired quantity, which eliminates the need for external hydrogen*.
Conventional ETJ
Uses extra energy for compression
and refrigeration between reactors.
Flexiforming
Patented integrated process design requires
no refrigeration and less compression,saving energy.

Future-proof flexibility to scalewith diverse feedstocks & products••

Flexiforming can profitably operate at small or large scale, enabling incremental
transition to SAF while leveraging existing infrastructure.
It provides flexibility to coprocess ethanol and methanol (e.g. produced from captured
CO2) while making SAF, gasoline, or liquid organic hydrogen carrier molecules for fuelcells in the same equipment.

*Aromatic molecules contain double bonds that do not need to be hydrogenated,unlike olefins that form during the conventional ETJ process.

WHY FLEXIFORMING?
Simple Process Lowers Costand Operating Complexity
Simple Processing Pathway
Dehydration, oligomerization
and aromatization occur in the same reactor.
Simple, Inexpensive Equipment
Similar equipment to naphtha hydrotreater;
catalyst has no precious metals.

100% Drop-in SAF Ready*Flexiforming can produce a 100% drop-in, fully
synthetic SAF*. This allows ethanol producers to sell
directly to airlines using common
carrier pipelines.

Flexiforming Process Flow (ETJ)

Flexiforming for SAF is a 2-stage process followed byhydrogenation of aromatics. Ethanol is dehydrated
into ethylene, then oligomerized and alkylated into
longer-chain molecules that form aromatic rings.
These are then hydrogenated to meet specificationsfor SAF. Dehydration and oligomerization occur in
one reactor vessel, optimizing heat transfer andreducing energy duty.

Scalable Bolt-On Installation
Flexiforming bolts onto existing infrastructure, allowing for
rapid deployment and ability to scale, profitably producing
ASTM-compliant fuels from 500 BPD (8 mil gallons per year)
to 10k+ BPD (150+ mil gallons per year).
Bolt-on installation converts all of the ethanol production
to SAF and/or other renewable fuels or chemicals using theexisting ethanol tankage and loadout facilities while reducing
transportation quantity by 40%.
*Subject to ASTM certification.

Commercially Proven
Technology
The Flexiforming catalyst and process
have been in commercial use since 2015.
Supported by 10 years of research andexperience, the technology has been
upgrading fossil naphtha to gasoline forthe past decade and is now optimized for
producing SAF.
