Dead, diseased trees, brush, slash piles from local forests and private lands.
Woody biomass is chopped, dried, blended for consistency and fed to the gasifier.
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.
In the final stage, the paraffinic wax is stripped to produce a zero sulfur, high cetane synthetic diesel fuel.
