<p><P>PROBLEM TO BE SOLVED: To facilitate maintenance of an apparatus by reducing an impurity component in a cracked oil formed by pyrolyzing a waste plastics including an impurity. <P>SOLUTION: There is provided a method for producing a cracked oil by pyrolyzing a plastics including an impurity to generate gaseous products and cooling the gaseous products. In the method, the plastics including the impurity in a thermal decomposition tank is heated and pyrolyzed to generate the gaseous products, a compound including the impurity of the gaseous products is made to stick to a sticking section provided in the thermal decomposition tank, and subsequent to sticking of the compound including the impurity to the sticking section, the component to be the cracked oil is stuck to the sticking section by making the temperature of the sticking section to be equal to the boiling point of the cracked oil or lower. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
