An Overview

The CharFuel®
Coal Refining Process

Coal and crude oil are both hydrocarbons. They can be refined in the same manner. Like crude oil, coal produces transportation, heating fuels, electricity generation feedstock (char), and petrochemicals. Refining coal using the CharFuel® Coal Refining Process removes pollutants from char prior to combustion or gasification.

Oil Refining Process
OIL: 2.0 Atoms Hydrogen to 1.0 Atom Carbon

Liquid Products
H = 2.2 Atoms | C = 1.0 Atom
Coke (Solids)
H = ≈0.0 Atoms | C = 1.0 Atom

The CharFuel® Coal Refining Process Combines Established & Proprietary Technologies

The CharFuel® Coal Refining Process [process graphic]
The CharFuel® Coal Refining Process is the only clean coal technology that refines coal into transportation fuels, electricity generation feedstock, and petrochemicals, as well as ammonia and sulfur, while inexpensively removing all pollutants, leaving no carbon footprint behind.

Compatible with Existing Distribution & Utilization Infrastructure

  • The CharFuel® Coal Refining Process yields coproducts similar to crude oil refining, including gasoline, Jet-A fuel, green diesel, and heating oil, as well as petrochemicals such as benzene, toluene, and xylene at costs less than that of comprable petroleum products.
  • Uses existing pipelines, tankers, and trains with no modification.
  • Utilizes existing refineries, distribution networks, engines, and provides clean fuel for existing power generation and distribution systems.
  • It is a clean, inexpensive and price stable, high BTU feedstock for efficient, high density IGCC generation which can connect directly to the grid.
  • Produces clean char for high heat rate combined cycle low emission electricity generation on brownfield sites.
