Abstract: The rare earth Zr catalyst, whose carrier was Al2O3, was prepared by coprecipitation with Zr(NO3)2, Al(NO3)3, and(NH2)2CO as the raw materials. The obtained catalyst was used to reform the waste plastic cracking product. As the Zr content in the catalyst increases, the yields of gasoline, gas, and the rate of carbon deposition increase, but the yields of diesel and heavy oil decrease. The optimum Zr content of the catalyst is 5%. At 290℃, with this most suitable catalyst, the yield of liquid fuel oil is the highest, about 86.10%, and research octance number(RON) of the gasoline is 92.15.
Key words: rare earth Zr catalyst; co-precipitation; waste plastic cracking
