Patent ID: 8178588

Claim:
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 selected from the group consisting essentially of coal, coke, solid waste and biomass material to said reaction chamber; providing H 2 O to said reaction chamber; introducing a gaseous stream containing carbon dioxide (CO 2 ) to said reaction chamber; reacting materials in said reaction chamber, wherein the reacting materials consisting essentially of said carbonaceous material, said H 2 O and said carbon dioxide (CO 2 ) from said gaseous stream to reduce said CO 2 and to form syngas comprising carbon monoxide (CO) and hydrogen (H 2 ), said reacting step further resulting in none of the provided carbonaceous material remaining as un-reacted carbonaceous material in said reaction chamber or said syngas; and discharging said formed syngas.
