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.

The present invention discloses a hypocrellin derivative substituted both in a pen-position and in a 2-position by an amino, and a preparation method and use thereof. A general structural formula of the derivative is as represented by formulas I-a to I-d:  The hypocrellin derivative substituted both in a peri-position and in a 2-position by an amino prepared in the present invention has a maximum absorption wavelength of 600-650 nm and a molar extinction coefficient reaching about 20000-40000 Mcm. Compared with unmodified hypocrellin or hypocrellin having only a 2-position modified, an absorption spectrum of the derivative is significantly red-shifted and the molar extinction coefficient is greatly improved, and the derivative can efficiently produce reactive oxygen species such as singlet oxygen in a photosensitive condition. In the same condition, the hypocrellin derivative substituted both in a pen-position and in a 2-position by an amino involved in the present invention, when used as a photosensitizer, has a stronger ability to photo-dynamically inactivate tumor cells than the first and second generation commercial photosensitizers.
