Syngas, or synthesis gas, is a mixture of hydrogen and carbon monoxide. It is produced through the gasification of carbon-containing materials, such as coal, natural gas, or biomass. Syngas serves as a versatile intermediate in the production of various chemicals, fuels, and energy. This gas can be converted into liquid fuels through processes like the Fischer-Tropsch synthesis. Additionally, syngas is used in the production of ammonia for fertilizers and can be utilized in fuel cells to generate electricity. Its ability to be derived from renewable sources makes it an important component in sustainable energy solutions.
