Upgrade low-value byproducts and enable direct sales
When HEFA processors maximize SAF over diesel, they produce 20% low-value byproductsof naphtha and LPG. Flexiforming turns these byproducts into a high-value aromatic SAF
blendstock that can be blended with paraffinic HEFA SAF on site. The resulting finishedproduct can be sold directly to airlines and airports*, even co-mingled with fossil jet via
common carrier pipelines and intermediate tankage.

Flexiforming’s integrated process design
minimizes energy duty
Key chemical reactions of Flexiforming occur in the same vessel, with no gaseousintermediate products to compress or refrigerate. Existing equipment like idle naphthahydrotreaters or catalytic reformers can be repurposed into a Flexiformer, reducing capitalcosts.

Flexiforming’s carbon cost of conversion is only 10%of feedstock’s carbon intensity (CI)
Flexiforming process gets all of its fuel gas from the feedstock, dramatically reducing
the need for external energy. Flexiforming of the naphtha and LPG into an aromatic SAF
generates hydrogen for the HEFA process.

*Subject to ASTM certification.

WHY FLEXIFORMING?
Flexiforming aromatic SAF is an excellent
and valuable blendstock.
Can be blended with paraffinic SAF
to produce 100% drop-in, fully synthetic SAF*
Can be blended with fossil jet

Simple Process Lowers Costand Operating Complexity
Simple, inexpensive equipment:
can re-use idle hydrotreaters or catalytic reformers;
catalyst contains no precious metals.

100% Drop-in SAF Ready*Works seamlessly with existing jet engines
and requires no additional airport infrastructure.

SAF Production Process

5K TPA Plant (120 BPD), 2019

Flexiforming Process Flow (With HEFA Integration)

Flexiforming for SAF is a two-stage
process that integrates into existing
HEFA plant infrastructure. It works bydehydrating the ethanol, producing
ethylene which then oligomerizes
and alkylates the naphtha into higher
molecular weight aromatics in the jet fuelboiling range. These reactions happen
in one reactor vessel, optimizing heattransfer and reducing energy duty.

Integration withExisting Infrastructure

Flexiforming integrates seamlessly with existing
infrastructure, allowing for rapid deployment
and ability to scale, profitably producing ASTMcompliant fuels from 200 BPD (3.1 mil gallons peryear) to 10k+ BPD (150+ mil gallons per year).

*Subject to ASTM certification.
