HYDROGEN PRODUCTION FROM NATURAL GAS AND CAPTURES OF CARBON DIOXIDE EMISSIONS

35725

In the near and medium term, increasing demand for hydrogen will be covered from fossil fuels, especially natural gas. This method of hydrogen production without releasing carbon dioxide into the atmosphere, producing a reasonable price for the environmental and economic is also appropriate. In order to achieve this, there are two basic options. The first one is that hydrogen production from natural gas as a conventional method and including carbon dioxide sequestration is steam-reforming method. Emitted carbon dioxide can be captured in the bottom of the ocean or sequestrated in geological formations such as oil and natural gas deposits. The second way is natural gas decomposition to produce pure hydrogen and oxygen at high temperatures. Hydrogen obtained from natural gas decomposition can be used as energy carrier. Carbon can be presented to the market such as building materials, electricity generation and improvement of soil to be used in various fields. In this study, hydrogen production process via conventional steam-reforming of natural gas and hydrogen and carbon as natural gas into high-temperature catalytic decomposition methods to technological, environmental and economic aspects were compared.
