  2. 2. RENALT ENERGY Renewable and Alternative Energy for the New Millennium What is Gasification? A Business Unit of GBH Enterprises, Ltd. Gasification converts any carbon-containing material into synthesis gas, composed primarily of carbon monoxide and hydrogen (referred to as syngas) Syngas can be used as a fuel to generate electricity or steam, as a basic chemical building block for a large number of uses in the petrochemical and refining industries, and for the production of hydrogen Gasification adds value to low- or negative-value feedstocks by converting them to marketable fuels and products

  4. 4. RENALT ENERGY Renewable and Alternative Energy for the New Millennium A Business Unit of GBH Enterprises, Ltd. Gasification – Differences from Combustion Add water and high pressure Use less air or oxygen Gasification exit gases are at high pressure, so smaller volume, smaller reactors Combustion makes heat + CO2 + H2O Gasification makes less heat + carbon monoxide + hydrogen (CO + H2); called Syngas
  5. 5. RENALT ENERGY Renewable and Alternative Energy for the New Millennium A Business Unit of GBH Enterprises, Ltd. So what can you do with CO and H2 ?
  6. 6. RENALT ENERGY Renewable and Alternative Energy for the New Millennium A Business Unit of GBH Enterprises, Ltd. Water-Gas-Shift (WGS) Reaction Dry syngas is ~ 40% CO + 50% H2 For each CO molecule the WGS reaction creates one H2 molecule and one CO2 molecule CO + H2O + catalyst CO2 + H2 After the WGS reaction, the CO2 and H2 can be separated High pressure CO2 results in lower cost sequestration Hydrogen can be burned to make power 2H2 + O2 2H2O
