A More Advanced Process

Renewable Diesel is made by adding hydrogen to natural fats and oils. Our process introduces the hydrogen in a more efficient manner, allowing the reactor temperatures to be uniform and controlled. This increases yield, lowers operating costs, and allows for feedstock flexibility.

A Better Fuel

  • 100% Renewable and Sustainable

    Our fuel is produced from inedible waste streams of agricultural oils and animal fats. In other words, we make fuel from the carbon that plants pull out of the air, instead of from oil in the ground.

  • High Performance

    Unlike biodiesel, Renewable Diesel is a pure hydrocarbon chain that is superior to fossil diesel. The high Cetane (80+) of our fuel delivers more power to the engine with noticeably increased mileage compared to standard diesel.

  • Easy to Use

    As a "drop-in" fuel, Renewable Diesel is molecularly equivalent to fossil diesel and has no blending limit. It is fully compatible with existing fuel distribution infrastructure without the need for additional investment.

  • Lower Emissions

    In addition to being renewably sourced, Renewable Diesel burns cleaner than fossil diesel by combusting more completely. This significantly reduces total hydrocarbon, particulate matter, carbon monoxide and nitrogen oxide (NOx) emissions.

The Chemistry

The technology Ryze is deploying in the Reno and Las Vegas facilities is a relatively simple chemical reaction that involves adding hydrogen (hydrogenation) to agriculture oils and animal fats.

Eco-friendly Renewable Diesel chemical process

All oils and fats are triglycerides, consisting of three fatty acids (hydrocarbon chains) connected by a glycerin. The main difference between fossil-fuel hydrocarbons and triglycerides is the presence of oxygen atoms in the glycerin.

To remove the oxygen, the triglycerides are hydrogenated in the presence of a catalyst. Hydrogen removes the oxygen from the molecule (deoxygenation) by forming H2O. This results in three straight-chain diesel molecules (C18H38), six water molecules (H2O), and one propane molecule (C3H8) for each triglyceride molecule that was hydrogenated.

Straight-chain diesel molecules from triglycerides have a high melting point and must be isomerized (re-arranged) to improve their cold-flow properties. After the isomerization, the diesel can be used by any diesel engine as a drop-in Renewable Diesel.

We have developed the most efficient and cost-effective method of hydrogenating triglycerides to produce Renewable Diesel.
