Synthesis Gas (Syngas)
Product of industrial-scale thermochemical reactions (including pyrolysis and catalytic reforming of methane) applied to organic matter, coal or natural gas in low-oxygen conditions. Synthesis gas is mainly made up of hydrogen (H2) and carbon monoxide (CO). Formerly used as a fuel (municipal gas and lighting), today it is mainly an intermediate material in the manufacture of chemicals and petrochemical compounds (hydrogen, ammonia, methyl ether, diesel, etc.).
