Abstract
A method and apparatus for refining waste plastic pyrolysis oil has an effect of converting the waste plastic pyrolysis oil into high value-added hydrocarbon oil having a high content of naphtha and kerosene, lowering a content of impurities such as chlorine, nitrogen, oxygen, and metal of the hydrocarbon oil, operating under milder process conditions, having excellent process efficiency, and having high process stability to be able to continuously produce refined oil.
