Hydrogen Production Technologies: Current State and Future

Addition of steam and/or oxygen in the gasification process results in the production of "syngas" with a H 2 /CO ratio of 2/1 the latter used as feedstock to a Fischer-Tropsch reactor to make higher hydrocarbons (synthetic gasoline and diesel) or to a WGS reactor for hydrogen production

Hydrogen (H 2 ) is currently used mainly in the chemical industry for the production of ammonia and methanol Nevertheless in the near future hydrogen is expected to become a significant fuel that will largely contribute to the quality of atmospheric air Hydrogen as a chemical element (H) is the most widespread one on the earth and as molecular dihydrogen (Hsub2/sub) can
