Abstract

The present disclosure relates to a method for producing light olefins and, more particularly, to a method for producing light olefins which can increase the production yield of light olefins and minimize the generation of carbon dioxide. The method for producing light olefins according to the present disclosure comprises the steps of: S1) pyrolyzing waste plastics to produce pyrolysis oil and pyrolysis gas; S2) separating the pyrolysis oil and pyrolysis gas; S3) producing a first gas from which impurities are removed by purifying the separated pyrolysis gas; S4) steam-reforming the first gas to manufacture a second gas; S5) producing a first synthesis gas from the second gas; S6) producing a second synthesis gas by converting carbon monoxide in the synthesis gas into hydrogen and carbon dioxide through a water gas shift reaction; S7) preparing a first mixed solution containing methanol by converting the second synthesis gas into methanol through a hydrogenation reaction; and (S8) preparing a second mixed solution containing light olefins through an olefin conversion reaction of methanol contained in the first mixed solution, and recovering the light olefins from the second mixed solution.
