Syngas is an abbreviated term for synthesis gas, which is a gaseous mixture of hydrogen, carbon monoxide, carbon dioxide, and other trace components. The term synthesis gas originally comes from the intermediate mixture for generating synthetic natural gas.

Syngas is also used as an intermediate for the  production of ammonia and urea, methanol, SNG, synthetic petroleum products, and other chemicals.

The main output of plasma gasification is the syngas that may be further processed to a variety of useful products as we show in the following PDF documents. Some products can be used immediately without further processing, while others require simple or complex conditioning and/or processing before use in specialty applications.

Methanation is the reaction where carbon oxides and hydrogen are converted to methane and water.

The methanation reactions are catalysed by nickel catalysts.

In the methanol industry, there are two typical uses for methanation: to purify synthesis gas and to produce methane for substitute natural gas (SNG).
