Woody Biomass

Extracted from the Black Hills by timber sub-contractor; delivered to our specs at the plant.

Feedstock prep

Woody biomass is chopped, dried, blended for consistency and fed to the gasifier.

gasification

Feedstock is gasified at high temps to  produce synthesis gas. The syngas is purified and reformed to produce carbon monoxide and hydrogen gases.

Converting Syngas to Liquid Fuel

Via Fischer–Tropsch chemical reaction processes, the syngas is transformed into a waxy paraffinic liquid fuel.

Hydrotreating

In the final stage, the paraffinic wax is stripped to produce a zero sulfur, high cetane synthetic diesel fuel.
