Syngas is a mixture of gases that mainly contains hydrogen and carbon monoxide, and sometimes carbon dioxide and methane as well. It is also known as synthesis gas. The name syngas comes from its use as an intermediate in creating synthetic natural gas, which is generally methane with the formula CH4. Syngas is produced by various methods such as coal gasification, steam reforming of natural gas or liquid hydrocarbons, and partial oxidation of natural gas or liquid hydrocarbons. The chemical composition of syngas varies based on the raw materials and the processes used to produce it. Syngas is used for various purposes such as:

• Producing ammonia or methanol
• Fuel gas in electricity generation
• Providing fuel power to internal combustion
• As an intermediate in preparing petroleum synthetic or fuel lubricant
• As a replacement for gasoline when gasoline supply has been limited

Syngas is a combustible gas and can be used as a fuel. It is also used as a fuel in hybrid turbines that allow for greater efficiency because of their lower operating temperatures and extended part lifetime.
