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.
Claims14
A process for producing syngas 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;
- introducing a gaseous stream containing carbon dioxide (CO2) to said reactor;
- reacting said carbon dioxide (CO2) and reactants in said gaseous stream to form a Syngas comprising carbon monoxide (CO) and hydrogen (H2);
- and
- providing said gas comprising carbon monoxide (CO) and hydrogen (H2) 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 (H2).
