Embodiment 1
[0020] This example illustrates that the sulfur content of gasoline can be significantly reduced by adopting the method provided by the invention.
[0021] 5 g PdCl 2 Dissolve in 180 g deionized water, add 5 g 36% HCl to help PdCl 2 of the dissolution. Add 310 grams of LV-23 to the resulting solution, stir evenly and place it for 1 hour, then dry it at 120°C, put it into a muffle furnace and bake it at 600°C for 4 hours, and then you can get the Pd loaded with metal element described in the present invention. catalyst, abbreviated as Pd-1.
[0022] In a fixed fluidized bed catalytic cracking unit, the gasoline raw materials shown in Table 1 are heated by a preheater and then mixed with atomized steam and enter the reactor. Contact and react with the regenerated Pd-1 catalyst in the reactor. Separation of the formed oil gas and catalyst. After the reaction oil and gas are cooled in three stages, cracked gas and liquid products are collected respectively. After the reactio...
Embodiment 2
[0024] This example illustrates that the sulfur content of gasoline can be significantly reduced by adopting the method provided by the invention.
[0025] 25.11 g of ZnCl 2 Dissolve it in 180 grams of water, add 310 grams of LV-23 to the resulting solution, stir evenly and let it stand for 1 hour, then dry it at 120 ° C, and then put it in a muffle furnace and bake it at 600 ° C for 4 hours to obtain the Zn-loaded catalytic cracking Catalyst, abbreviated as Zn-1.
[0026] 5 g PdCl 2 Dissolve in 250 grams of water, add 5 grams of 36% HCl to help PdCl 2 of the dissolution. Add 310 grams of Zn-1 to the resulting solution, stir evenly and place it for 1 hour, then dry it at 120°C, put it into a muffle furnace and bake it at 600°C for 4 hours, and then you can get the supported metal elements Zn and Zn in the present invention. The Pd catalyst is abbreviated as PdZn-1.

Embodiment 3
[0029] This example illustrates that the sulfur content of gasoline can be significantly reduced by adopting the method provided by the invention.
[0030] 14.82 g Co(NO 3 ) 2 ·6H 2O was dissolved in 180 grams of water. Add 310 grams of Zn-1 to the resulting solution, stir evenly and place it for 1 hour, then dry it at 120°C, put it into a muffle furnace and bake it at 600°C for 4 hours, and then you can get the supported metal elements Zn and Zn in the present invention. The catalyst of Co is abbreviated as CoZn-1.
[0031] In a fixed fluidized bed catalytic cracking unit, the gasoline raw materials shown in Table 1 are heated by a preheater and then mixed with atomized steam and enter the reactor. Contact and react with the regenerated CoZn-1 catalyst in the reactor. Separation of the formed oil gas and catalyst. After the reaction oil and gas are cooled in three stages, cracked gas and liquid products are collected respectively. After the reaction, the carbon-deposit...
