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 Â°C), without combustion, with a controlled amount of oxygen and/or steam. The resulting gas mixture is called syngas (from synthesis gas or synthetic gas) or producer gas and is itself a fuel. The power derived from gasification and combustion of the resultant gas is considered to be a source of renewable energy if the gasified compounds were obtained from biomass.
Coke is carbonized coal, a product produced by baking coal in a heated oven. By using a process that allows the impurities in the coal to be burned off, while not allowing the carbon content of the coal to burn, the coal is turned into coke. The impurities burned off were actually the volatile matter contained in the coal, such as tars, oils and gases. When burned, coke generated an intense amount of heat but produced very little smoke, qualities that made it an ideal fuel for use in producing iron and steal. During the 1880's, coke began to replace charcoal in the making of steel at foundries in the United States.
