Abstract

PROBLEM TO BE SOLVED: To efficiently and economically decompose/remove nitrogenous compounds and/or chlorinated compounds from a decomposed oil of waste plastics to prepare a refined oil by treating the decomposed oil with steam in the presence of a catalyst. SOLUTION: A decomposed oil that is a decomposition product of waste plastics is treated with steam in the presence of a catalyst, so that at least either of nitrogenous compounds or chlorinated compounds contained in the oil are decomposed/removed to produce a refined oil. In the above treatment, it is preferred that the treating temperature is 200-600 deg.C, the catalyst used is a catalyst in the catalytic cracking of petroleum (e.g. alumina), and the amount of steam is 0.1-50m<3> (NTP) for each 1kg of the decomposed oil. 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.

ることが判った。Example 6 As a refining device, a magnesia catalyst (spherical; in a heat-resistant glass reaction tube (inner diameter 25 mm x length 700 mm);
What was filled with 20 ml of an average diameter of 3 mm was heated to a temperature of 500 ° C., and waste plastic decomposition oil (nitrogen content 1500 ppm and chlorine content 1500 ppm) and water were circulated in the reaction tube at a flow rate of 20 ml / h. The distributed oil and water passed through the catalyst layer while vaporizing on the surface of the catalyst. The gas mixture flowing out of the reaction tube was cooled, and oil and water were separated from the obtained liquid mixture. Analysis of the separated oil revealed a nitrogen content of 340 ppm and a chlorine content of 10 ppm.
