Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for conversion of waste plastic to oil that has a sufficiently high rate of conversion to oil.SOLUTION: A method for conversion of waste plastic to oil according to the present invention includes the steps of: feeding crushed waste plastic as a raw material into iron pyroligneous acid 7 as a heat medium preheated to a temperature range of 350-500°C in a reactor 1; mixing the waste plastic into the iron pyroligneous acid 7 by stirring means 3 and decomposing the waste plastic by the high-temperature iron pyroligneous acid 7 on a contact surface with the iron pyroligneous acid 7 to produce cracked gas; and cooling the cracked gas to produce cracked oil.SELECTED DRAWING: Figure 1 【課題】油化率が十分に高い廃プラスチックの油化方法を提供すること。【解決手段】本発明の廃プラスチックの油化方法は、反応器１内で３５０℃〜５００℃の温度域に予め加熱した熱媒体としての木酢酸鉄液７に破砕した廃プラスチックを原料として投入する工程と、撹拌手段３によって木酢酸鉄液７中に前記廃プラスチックを混合し、前記廃プラスチックを木酢酸鉄液７との接触面において高温の木酢酸鉄液７によって分解させて分解ガスを生成する工程と、前記分解ガスを冷却し分解油を生成する工程と、を備えることを特徴とする方法である。【選択図】図１
