Coal gas Wikipedia

Coal gas Wikipedia

This is the only such plant surviving in the United States. Manufactured gas can be made by two processes: carbonization or gasification. Carbonization refers to the devolatilization of an organic feedstock to yield gas and char. Gasification is the process of subjecting a feedstock to chemical reactions that produce gas. [10] [11]
