Abstract
A system and method for reducing 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.
Claims19
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 1,330° 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 reactor;
- and
- reacting said carbonaceous material said H2O and said carbon dioxide (CO2) and reactants in said gaseous stream to form a gas comprising carbon monoxide (CO) and hydrogen (H2) (i.e. Syngas) 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.
