Abstract: Catalytic cracking is an efficient method for bio-oil upgrading. However, the catalyst was prone to coking and deactivating in upgrading process. This leads to the decrease of quality of upgrading bio-oil. Therefore, the non-thermal plasma(NTP) assisted catalytic cracking reactor with zeolite catalyst was designed. The effects of the operating parameters on yield and physicochemical properties of upgraded bio-oil were studied. Under the optimum operating parameters, i.e., the catalyst temperature of 400℃, catalyst bed height of 35 mm and reactor discharge power of 25 W, the yield of upgraded bio-oil, oxygen content, higher heating value(QHHV), pH value and heavy component were obtained as 9.13%, 15.78%, 34.86 MJ/kg, 5.41, 3.15%, respectively. In terms of thermal gravimetric analysis, the total coke amount on the surface of the catalyst decreased from 5.88% to 2.14% through the methodology of NTP assisted HZSM-5.
