Self-random oxidation and polymerization processes occur in the pyrolysis gasoline production as well as during its storage until the moment when it is used as a feedstock for xylene production. As a result dense products are accumulated on the equipment internal walls. Therefore, the equipment operation becomes more difficult and some key aromatic hydrocarbons, such as styrene, vinyl, toluene etc. are lost. The purpose of the present study is to choose the most appropriate oxidation and polymerization inhibitors to suppress these processes.
