摘要：

A plasma pre-discharge enhanced catalysis system was prepared to study bio-oil upgrading using HZSM-5. The response surface methodology was employed to analyze the effects of reaction temperature, height of catalyst loading and discharge power on refined bio-oil yields. Moreover, Ti/HZSM-5 was introduced for bio-oil catalysis under the optimal conditions and the catalytic mechanism was explored. The results show that all factors have obvious effects on yields with interactions between the factors. The optimal yield was 18.1% under conditions of reaction temperature 400 ℃, height of catalyst loading 20 mm and discharge power 30 W, which was similar to the predicted value of 18.5%. The performance of cracking deoxidization was obviously enhanced and the refined bio-oil yield decreased to 16% when Ti/HZSM-5 was introduced. However, the content and composition of hydrocarbons were obviously increased. The polycyclic aromatic hydrocarbons were reduced to 6.33%, and the C14 and above hydrocarbons were only 2.81%. The pre-discharge provides materials for the subsequent catalysis, and the impact of energetic substances enhances catalyst activity and changed adsorption characteristics of reactants. The interaction between Ti ions and active substances promotes the carbonium ions reactions. Finally, monocyclic aromatic hydrocarbons were formed under hydrocarbon pool mechanism. © 2019, Editorial Board of Journal of Chemical Engineering of Chinese Universities". All right reserved."
