Carbon Monoxide

Formula: CO

Carbon monoxide is a compound of carbon and oxygen with the chemical formula CO. It is a colorless, odorless, tasteless, toxic gas. Carbon monoxide is the twelfth most abundant gas in the atmosphere. The major natural source of carbon monoxide is the combustion of wood, coal, and other naturally occurring substances on the Earth’s surface.

Huge quantities of carbon monoxide are produced, for example, during a forest fire or a volcanic eruption. Commercial methods for producing carbon monoxide often depend on the direct oxidation of carbon under controlled conditions. In the form of producer gas or water gas, it is widely used as a fuel in industrial operations. The gas is also an effective reducing agent. For example, when carbon monoxide is passed over hot iron oxides, the oxides are reduced to metallic iron, while the carbon monoxide is oxidized to carbon dioxide. Carbon monoxide has been proposed for use as a fuel on Mars.

Carbon monoxide/oxygen engines have been suggested for early surface transportation use as both carbon monoxide and oxygen can be straightforwardly produced from the carbon dioxide atmosphere of Mars by zirconia electrolysis, without using any Martian water resources to obtain hydrogen, which would be needed to make methane or any hydrogen-based fuel.
