    Gasification - Wikipedia

    Gasification is a process that converts organic- or fossil fuel-based carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide.This is achieved by reacting the material at high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam.The resulting gas mixture is called syngas (from synthesis gas) or producer gas and is itself a fuel.
