Natural gas can be converted to pure methane with H2 through a process called steam methane reforming. In this process, natural gas is mixed with steam and then heated to high temperatures, which causes a chemical reaction that produces carbon monoxide and hydrogen. The carbon monoxide is then reacted with steam to produce additional hydrogen and carbon dioxide. The resulting mixture of hydrogen and carbon dioxide is then processed through a water-gas shift reaction to convert the carbon dioxide into more hydrogen. Finally, the hydrogen is purified to produce pure methane. **
