Select true or false: substitute natural gas can be synthesized by passing carbon monoxide and hydrogen over ni or co at 400°c.

This statement is "False".
Synthetic natural gas is usually created from coal. This gas acts as a substitute to natural gas. It must contain at least 95% methane. The intermediate step of creating synthetic gas is known as the synthesis gas production which is done through steps of gasification (using carbon and oxygen) followed by reactions of water gas shift and methanation (using carbon monoxide and steam)
