Patent ID: 7932298

Claim:
A process for producing syngas that reduces the amount of carbon dioxide in a gaseous stream, the process comprising: maintaining a reaction chamber at a temperature of between 400° C. and 5000° C. and at a pressure of about one bar or greater; providing a carbonaceous material in said reaction chamber; providing H 2 O to said reaction chamber; introducing a gaseous stream containing carbon dioxide (CO 2 ) to said reactor; reacting said carbonaceous material, said H 2 O and said carbon dioxide (CO 2 ) in said gaseous stream to form a Syngas comprising carbon monoxide (CO) and hydrogen (H 2 ), wherein the mole ratio of H2O expressed as a percentage of CO2 consumed to carbonaceous material consumed provided to the reaction chamber is about 34.33% and said reacting step further resulting in none of the carbonaceous material remaining as un-reacted carbonaceous material; and providing said gas comprising carbon monoxide (CO) and hydrogen (H 2 ) to a water-gas shift reactor to adjust the carbon monoxide and hydrogen molar ration to between 0.2 to 5.0 molecules of carbon monoxide (CO) and 5.0 to 0.2 molecule of hydrogen (H 2 ).
