What is Syngas?

"Syngas is an abbreviation for synthesis gas"

"There are two by-products resulting from this process; syngas, a compound of hydrogen and carbon monoxide, which can be turned into fuel, and molten glass which has several applications including the manufacture of tiles and road asphalt."

"Plasma Converter draws its power from the electrical grid to get started. The initial voltage is about equal to the zap from a police stun gun. But once the cycle is under way, the 2,200 F syngas is fed into a cooling system, generating steam that drives turbines to produce electricity."

"Plasma Converter System transforms these feedstock materials into a syngas (plasma converted gas—PCG) rich in carbon, hydrogen and oxygen"

"Syngas, also called a synthesis gas, is a mix of molecules containing hydrogen, methane, carbon monoxide, carbon dioxide, water vapours, as well as other hydrocarbons and condensable compounds. It is a main product of gasification"

"Syngas from biomass and solid waste is a carbon-neutral fuel believed to be a promising fuel for future engines. It was widely used for spark-ignition engines in the WWII era before being replaced with gasoline."
