Question
What do you understand by the term syngas?
Solution
Syngas is a mixture of carbon monoxide and dihydrogen. Since the mixture of the two gases is used for the synthesis of methanol, it is called syngas, synthesis gas, or water gas.
Syngas is produced on the action of steam with hydrocarbons or coke at a high temperature in the presence of a catalyst.
\[\ce{C_nH_{2n+2} + nH2O ->[1270 K][Ni] nCO + (2n + 1)H2}\]
For example:
\[\ce{CH_{4(g)} + H2O_{(g)} ->[1270 K][Ni] \underset{Syn gas}{CO_{(g)} + 3H_{2(g)}}}\]
