摘要：
A method and system for pretreating waste plastics and a method and system for producing an automotive fuel from waste plastics are provided. The method for pretreating waste plastics includes the steps of: 1) contacting a waste plastic with a pretreating agent and a solvent oil for impurity removal; and 2) subjecting the effluent from step 1) to solid-liquid separation to obtain an insoluble material and an impurity-removed plastic-containing solution. The impurity-removed plastic-containing solution obtained by the method and system for pretreating waste plastics has very low metal content, chlorine content and silicon content.
