synthesis gas

n. A mixture of gases made as feedstock for chemical processes or industry, especially a fuel produced by controlled combustion of coal in the presence of water vapor. Also called syngas.

synthesis gas

n 1. (Chemistry) a mixture of carbon dioxide, carbon monoxide, and hydrogen formerly made by using water gas and reacting it with steam to enrich the proportion of hydrogen for use in the synthesis of ammonia 2. (Chemistry) a similar mixture of gases made by steam reforming natural gas, used for synthesizing organic chemicals and as a fuel

syn′thesis gas`

n. any of several gaseous mixtures consisting essentially of carbon monoxide and hydrogen, used in the synthesis of chemical compounds, as ammonia and alcohols. [1940–45]

Synthesis Gas

synthesis gas

[′sin·thə·səs ‚gas] (chemical engineering) A mixture of gases prepared as feedstock for a chemical reaction, for example, carbon monoxide and hydrogen to make hydrocarbons or organic chemicals, or hydrogen and nitrogen to make ammonia. Also known as syngas.

Synthesis Gas

a synthetic gas produced by the gasification of solid fuels in gas generators into which a mixture of oxygen and steam can be blown. Ideally, synthesis gas contains 66 percent CO and 34 percent H₂ by volume; however, under real conditions it also contains such components as nitrogen, carbon dioxide, and methane. Synthesis gas is used in industry mainly as a raw material in chemical processing. Its high cost of production relative to other gases makes its use as a fuel economically unfeasible.
