Abstract
A system and method for producing Syngas from the CO2 in a gaseous stream, such as an exhaust stream, from a power plant or industrial plant, like a cement kiln, is disclosed. A preferred embodiment includes providing the gaseous stream to pyrolysis reactor along with a carbon source such as coke. The CO2 and carbon are heated to about 1330° C. and at about one atmosphere with reactants such as steam such that a reaction takes place that produces Syngas, carbon dioxide (CO2) and hydrogen (H2). The Syngas is then cleaned and provided to a Fischer-Tropsch synthesis reactor to produce Ethanol or Bio-catalytic synthesis reactor.
Claims31
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 H2O to said reaction chamber;
- introducing a gaseous stream containing carbon dioxide (CO2) to said reaction chamber;
- reacting materials in said reaction chamber, wherein said reacting materials consisting essentially of said carbonaceous material, said H2O and said carbon dioxide (CO2) from said gaseous stream to reduce said CO2 and to form syngas comprising carbon monoxide (CO) and hydrogen (H2), said reacting step further resulting in none of the carbonaceous material remaining as un-reacted carbonaceous material in said syngas;
- discharging said formed syngas from said reaction chamber;
- and
- providing said formed syngas comprising carbon monoxide (CO) and hydrogen (H2) to a water-gas shift reactor to adjust the carbon monoxide and hydrogen molar ratio to between 0.2 to 5.0 molecules of carbon monoxide (CO) and 5.0 to 0.2 molecules of hydrogen (H2).
