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.
Adsorption involves the odour âstickingâ to the inside steel walls of the gas bottle. Absorption refers to the odour being absorbed by another substance such as water. Oxidation occurs when the inside of a gas bottle is exposed to air, causing a chemical reaction which can result in LPG losing its smell.
