The Production of Hydrogen Gas: Steam Methane
2016-7-14 Steam Methane Reforming Process First, water must be heated in a furnace to produce steam. The superheated steam is mixed with natural gas in the reforming reaction, producing hydrogen gas and carbon monoxide. Carbon monoxide from the reforming reaction interacts with water again to produce more hydrogen and carbon dioxide.

Review on Innovative Catalytic Reforming of Natural Gas
Steam reforming is the main reforming process of methane that is predominantly utilized because it has the greatest value for H 2 /CO ratio, i.e., the product of the reforming process is a gas flow considered ideal for the development of the catalytic process of obtaining a gas hydrogen flow of high purity. However, as the process of steam ...
