Method for reducing CO₂in a gaseous stream by conversion to a Syngas for production of energy

摘要

A system and method for reducing the CO2 in a gaseous stream between 33% up to and even in excess of 90%, by reducing CO2. A gaseous stream that includes substantial amounts of CO2 is provided to a reaction chamber along with H2O (steam) and a carbon source such as charcoal, coke or other carbonaceous material. Carbon is provided to the chamber at a ratio (C/CO2) of between about 0.100 to 0.850, and between about 0.200 to 0.900 of H2O to the provided CO2. The CO2, H2O and carbon are heated to between about 1500° F. and about 3000° F. at about one atmosphere to produce syngas (i.e. carbon monoxide (CO) and hydrogen (H2)) and reduces the amount of CO2. The Syngas may then be cleaned and provided to a Fischer-Tropsch synthesis reactor or a Bio-catalytic synthesis reactor to produce a fuel, such as Methanol, Ethanol, Diesel and Jet Fuel.

主权项

1. A process for generating syngas from CO2, the process comprising:
maintaining said reaction chamber at a temperature of at least 1500° F. (815.6° C.) and at a pressure of about one bar or greater; providing a gaseous stream containing carbon dioxide (CO2) at a first selected rate to said reactor as a feed gas; providing carbon (C) to said reaction chamber at a second selected rate, the ratio of said provided carbon with respect to the provided CO2 being between about 0.200 and 0.900; providing H2O to said reaction chamber at a third selected rate, the ratio of said provided H2O with respect to said provided CO2 being between about 0.100 and 0.500; and reacting said carbon, said H2O and said carbon dioxide (CO2) in said gaseous stream to reduce said provided CO2 by at least 30% to form a syngas comprising carbon monoxide (CO) and hydrogen (H2), and said second selected rate at which said carbon is provided to said reaction chamber is the same rate as said carbon is combined with oxygen to form said CO such that all of said provided carbon exits said reaction chamber in the form of CO or CO2 as said syngas.
