Abstract
Provided is a method of manufacturing syngas including (S1) heat-treating organic wastes under a catalyst in a first reactor to produce a first mixed gas; (S2) separating the catalyst and carbon dioxide (CO2) from the first mixed gas, and recovering a mixed gas from which the catalyst and the carbon dioxide (CO2) have been removed; (S3) converting the carbon dioxide (CO2) separated in (S2) into carbon monoxide (CO) by a reverse Boudouard reaction in a second reactor; and (S4) mixing the mixed gas recovered in (S2) and the carbon monoxide (CO) converted in (S3) to produce syngas.

A method for manufacturing syngas, the method comprising:
- (S1) heat-treating organic wastes under a catalyst in a first reactor to produce a first mixed gas;
- (S2) separating the catalyst and carbon dioxide (CO2) from the first mixed gas, and recovering a second mixed gas from which the catalyst and the carbon dioxide (CO2) have been removed;
- (S3) converting the carbon dioxide (CO2) separated in (S2) into carbon monoxide (CO) by a reverse Boudouard reaction in a second reactor;
- and
- (S4) mixing the second mixed gas recovered in (S2) and the carbon monoxide (CO) converted in (S3) to produce syngas.
An apparatus for manufacturing syngas comprising:
- a first reactor where organic wastes are introduced and a methane reforming reaction and a gasification reaction are simultaneously performed under a catalyst to form a product;
- a carbon dioxide separation unit where the product is introduced from the first reactor and carbon dioxide is separated;
- a second reactor where the carbon dioxide separated from the carbon dioxide separation unit is introduced and a reverse Boudouard reaction is performed;
- and
- a syngas production unit where a product from which the carbon dioxide has been removed in the carbon dioxide separation unit and carbon monoxide converted in the second reactor are mixed to produce syngas.
