OUR TECHNOLOGY

 

Cetna Energy utilizes a proprietary advanced thermochemical conversion platform capable of converting nearly any carbon‑containing raw material into renewable natural gas (RNG), green methanol, green hydrogen, and other renewable liquid fuels such as; sustainable aviation fuel, renewable diesel and gasoline, and ethanol.   Our system can also be configured to produce a wide range of high‑value energy products, including commodity chemicals, industrial gases, and electricity.

While our primary focus is woody biomass from mill residues, our technology has been successfully tested on a broad spectrum of renewable and low‑cost feedstocks—including coal, petroleum residues, sewage sludge, pulp sludge, and other “at‑need” materials. This flexibility allows Cetna to serve diverse markets while supporting responsible waste‑to‑energy solutions.

Proven, Optimized Technology

Cetna Energy’s process has been refined through more than 35,000 hours of pilot and demonstration run time, resulting in a highly efficient, commercially ready platform. Three core operating characteristics set our technology apart:

  • Precise control of contact and reaction time within the Fischer–Tropsch (FT) reactor

  • Optimized temperature distribution throughout the FT reactor system

  • Tight control of syngas ratios to maximize conversion efficiency and product yield

Cetna’s proprietary thermochemical system integrates advanced gasification/reformation with Fischer–Tropsch catalysis. We also own and deploy our own proprietary FT catalysts.

Unlike traditional Lurgi or fluidized‑bed reactors, our multi‑reactor gasification design operates at higher, more controllable temperatures. These conditions enable more complete feedstock utilization and produce a cleaner, more effective synthetic gas. As a result, Cetna achieves 30–40% higher yields than competing designs.

 Modular, Efficient, and Low‑Emission

Cetna’s commercial plants are built in 50‑ton‑per‑day modules, allowing scalable deployment and operational flexibility. Our design relies on off‑the‑shelf equipment, reducing capital cost, simplifying maintenance, and accelerating construction timelines.

Our system has virtually no design vents, meaning the only emissions are minor fugitive emissions from pumps, valves, and similar components. Independent analysis by Auburn University estimates 80–90% reductions in greenhouse gas emissions compared to conventional fossil‑based processes.
