2 METHOD FOR PREPARING SELECTIVE NAPHTHA OIL THROUGH SECONDARY PYROLYSIS OF WASTE OIL

The present invention relates to a method for manufacturing naphtha from mixed plastics, including the steps of: (a) thermal cracking the mixed plastics; (b) separating the product of the thermal cracking step into a first oil having a boiling point of less than 150 deg. C and a second oil having a...

More Information
Summary:The present invention relates to a method for manufacturing naphtha from mixed plastics, including the steps of: (a) thermal cracking the mixed plastics; (b) separating the product of the thermal cracking step into a first oil having a boiling point of less than 150 deg. C and a second oil having a boiling point other than that; and (c) catalytic cracking the second oil. 본 발명은 (a) 혼합 플라스틱을 열분해(thermal cracking)하는 단계; (b) 상기 열분해 단계의 생성물을 150℃ 미만의 비점을 갖는 제1 유분과 이외의 비점을 갖는 제2 유분으로 분리하는 단계; 및 (c) 상기 제2 유분을 촉매분해(catalytic cracking)하는 단계를 포함하는, 혼합 플라스틱에서 납사를 제조하는 방법에 관한 것이다.
