Such as cement kilns, from the power plant or industrial equipment, systems and methods for producing synthesis gas from CO 2 in the gas stream such as the exhaust stream is disclosed. Preferred embodiments include feeding the gas stream to a pyrolysis reactor along with a carbon source such as coke. The CO 2 and carbon, together with a reactant such as water vapor, are brought to about 1330 ° C. at about 1 atm so that a reaction that produces synthesis gas, carbon dioxide (CO 2 ), and hydrogen (H 2 ) occurs. Heated. The synthesis gas is then cleaned and fed to a Fischer-Tropsch synthesis reactor or biocatalytic synthesis reactor for producing ethanol. |
