Abstract

PROBLEM TO BE SOLVED: To efficiently and economically remove nitrogenous compounds from a decomposed oil of waste plastics to prepare a refined oil by treating the decomposed oil with sulfuric acid. SOLUTION: A cracked oil that is a decomposition product of waste plastics is treated with sulfuric acid, so that nitrogenous compounds contained in the oil are removed to prepare a refined oil. In the above treatment, it is desired that the treating temperature is 0-100 deg.C, the sulfuric acid used is sulfuric acid or fuming sulfuric acid with a sulfuric acid concentration of 50-100vol.%, and the amount of the sulfuric acid used is 0.1-100 pts.vol./(one treatment) per 100 pts.vol. of the decomposed oil. According to the refining, the refined oil is produced efficiently and economically from the decomposed oil of waste plastics. Further, by subjecting the refined oil to a steam cracking treatment, 1-olefins such as ethylene and propylene and conjugated diolefins such as butadiene can be reclaimed in purities usable as petrochemical raw materials.
