Method and apparatus for reducing CO₂in a stream by conversion to a syngas for production of energy

摘要

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.

主权项

1. A process for producing syngas that reduces the amount of carbon dioxide in a gaseous stream, the process comprising:
providing a reaction chamber, said reaction chamber selected to be one of a pyrolysis reactor, a conventional gasifier or a plasma arc gasifier; providing a carbonaceous material in said reaction chamber; providing H2O to said reaction chamber; introducing a gaseous stream containing carbon dioxide (CO2) into said reaction chamber; maintaining said reaction chamber at a temperature of between 400° C. and 5000° C. and at a pressure of about one bar or greater to react materials in said reaction chamber, the reacting materials consisting essentially of said carbonaceous material, said H2O and said carbon dioxide (CO2) in said gaseous stream to form syngas comprising carbon monoxide (CO) and hydrogen (H2), wherein an amount of CO2 in said syngas is at least 53% less than an amount of CO2 that was provided in said gaseous stream; and discharging said formed syngas.
