Method of processing exhaust gas
(57) In a method of processing exhaust gas containing CO2, such as exhaust gas from a cement production plant, the following steps are carried out: – burning fuel in the combustion reactor with the O2 content of the exhaust gas being used as an oxidizing agent, – controlling the combustion in the combustion reactor so that the exhaust gas from the combustion reactor contains less than 10 vol. -% of oxygen and at least 80 vol.-% of a mixture of CO and CO2, feeding the exhaust gas from the combustion reactor into a conversion reactor, in which the CO2 and optionally the CO contained in the exhaust gas is converted into a hydrocarbon fuel.
