Question

why Methane is called as marsh gas?

Answer 1

Because it is the product of decay in swamps and marshes from organic material underwater and in the muck.

The main process for the production of methane is anaerobic digestion that takes place over at least 30 to 60 days.

Here is a bit from Wikipedia on anaerobic digestion:

Four stages of anaerobic digestion have been recognised.

The first is hydrolysis, where complex organic molecules are broken down into simple sugars, amino acids, and fatty acids with the addition of hydroxyl groups.

The second stage is acidogenesis where a further breakdown into simpler molecules occurs, producing ammonia, carbon dioxide and hydrogen sulfide as byproducts.

The third stage is acetogenesis where the simple molecules from acidogenesis are further digested to produce carbon dioxide, hydrogen and mainly acetic acid, although higher-molecular-weight organic acids (e.g., propionic, butyric, valeric) are also produced.

The fourth stage is methanogenesis where methane, carbon dioxide and water are produced.

Answer 2

Methane is called Marsh gas because it is produced when vegetation decomposes naturally with in some geographical marshes, swamps and bogs. the main process for the production of methane is aneorobic digestion..............
