What is the composition of syn gas?

Syngas, or synthesis gas, primarily consists of hydrogen (H₂) and carbon monoxide (CO), with varying amounts of carbon dioxide (CO₂) and traces of other gases such as methane (CH₄) and water vapor (H₂O). The typical H₂ to CO ratio in syngas can range from 1:1 to 3:1, depending on the production process. It is commonly produced through methods like gasification or steam reforming and serves as an important intermediate for producing fuels and chemicals.
