Embodiment 1
[0057] Embodiment 1 (the present embodiment is comparative example)
[0058] The FCC catalyst TJPC-F produced by Sinopec Changlian Catalyst Factory has an LOI of 12.1% and an ABD of 0.90g / cm 3 , The wear coefficient is 5.87% / hr.
Embodiment 2
[0060] The TJPC-F catalyst in Example 1 was calcined at 550° C. for 2 hours in a muffle furnace under atmospheric pressure and normal pressure to become TJPC-F-C1. The LOI of the catalyst after calcination is 0.5%, and the ABD is 0.81g / cm 3 , The wear coefficient is 1.81% / hr.
Embodiment 3
[0062] The TJPC-F catalyst in Example 1 was dried in an oven at 110° C. for different times to remove moisture and other volatile matter in the catalyst. The LOI values of the catalyst samples are different with different drying times, and the longer the drying time, the lower the LOI. The wear resistance performance results measured under different LOIs are shown in Table 1.
