PROCESS

From start to finish, Red Rock’s process consists of six simple steps:

Step 1.  Feedstock Sourcing & Transportation
Step 2.  Material Handling
Step 3.  Gasification
Step 4.  Fischer-Tropsch
Step 5.  Product Upgrading
Step 6.  Product Offtake

STEP 1: Feedstock Sourcing and Transportation

Waste woody biomass is produced from nearby forestry operations.

  • Red Rock sources its waste woody biomass feedstock from surrounding forests within about a 125-mile feedstock draw radius from suppliers under a mix of long-term and short-term contracts.
  • Red Rock purchases its waste woody biomass feedstock on a delivered basis, in 3-4″ minus chip size.

STEP 2: Material Handling

“Playground” sized chips are ground to “chainsaw” sized chips.

  • Truck tipper unloads the biomass material into a storage pile.
  • The waste woody biomass is conveyed to screeners and grinders to reduce the chip size prior to entering the gasifier.

STEP 3: Gasification

Biomass is transformed into syngas (CO + H2) + biochar then cleaned to remove contaminants

  • Waste woody biomass is converted into synthetic gas or “syngas” via the gasification unit.
  • The gasification unit is comprised primarily of the horizontal pyrolysis chamber and a recycle heater unit.
  • Biochar is also created as a coproduct from gasification.
  • As a second stage, produced syngas is fed into a clean-up and conditioning system to remove contaminants such as tar and residual solids.

STEP 4: Fischer-Tropsch

Clean syngas (CO + H2) are converted into sustainable hydrocarbons.

  • The cleaned syngas enters the Fischer-Tropsch (“FT”) unit where it is converted into long-chain hydrocarbons.
  • The syngas (CO + H2) is fed into this system, where it creates synthetic crude.  Synthetic crude is chemically similar to crude oil but without the geological contaminants.
  • The synthetic crude is then transported as waxes and oils into the next phase of the process.

STEP 5: Product Upgrading

Synthetic renewable crude is refined into SAF & Renewable Diesel.

  • The product upgrading process converts waxes and liquids from the FT reactors into finished jet and diesel fuels within a hydro-processing /distillation unit.
  • The long carbon chains of the synthetic crude are chemically split with hydrogen to produce finished products.

STEP 6: Product Offtake

The finished product is now ready for shipment.

  • The SAF and Renewable Diesel would be trucked or railed to the purchasers in the Bay Area of California or beyond.
  • The Company maintains current offtake agreements for a total of 6 million gallons per year of renewable jet fuel.
