Description

Application

Methane is a colourless, odourless, and flammable gas that is lighter than air. Methane is used as a fuel for power generation in gas turbines and steam boilers; household cooking and heating, and for vehicles (compressed natural gas, CNG). It is also a feedstock of choice for production of hydrogen, carbon monoxide, methanol, acetic acid, and myriad organic compounds. Gas is easy to handle in a small, light pressure can, while the disposable container allows for aluminium recycling when finished.

Features and Benefits

Methane is used as a carbon source for the chemical vapor deposition (CVD) of carbide and diamond thin films.
