[0018] Preparation of Catalyst-1
[0019] commercially available SnCl 4 ·5H 2 O 20g with FeCl 3 ·6H 2 O 1.71g (produced by Sinopharm Chemical Reagent Co., Ltd.) was dissolved in 200 mL of distilled water, and 25% (w / w) ammonia water was added under stirring to adjust the pH to 8, aged at room temperature for 24 hours, suction filtered, and passed through 2% ammonium acetate solution Wash to remove Cl - (with 0.1 mol / L AgNO 3 inspection), the filter cake was dried at 100°C for 24 hours, ground to 100 mesh, and placed in 1mol / L (NH 4 ) 2 S 2 o 8 solution (15 mL / g), then filtered, dried, and calcined at 550°C for 5h to obtain the S 2 o 8 2- / SnO 2 -Fe 2 o 3 Catalyst (Fe / Sn molar ratio is 1:9).
[0020] Preparation of Catalyst-2
[0021] SnCl 4 ·5H 2 O 20g with FeCl 3 ·6H 2 O 3.86g (produced by Sinopharm Chemical Reagent Co., Ltd.) was dissolved in 200 mL of distilled water, and 25% (w / w) ammonia water was added under stirring to adjust the pH to 9, aged at...

[0039] Example 1: Using Catalyst-1 to Crack Papermaking Waste Residue
[0040] Dry the papermaking waste residue (waste plastic) to make the moisture less than 5%, crush it, feed it evenly into the fluidized bed cracking kettle, and crack it at 300°C under the action of Catalyst-1 (30%), catalytic cracking for 1 hour, the The fuel oil components are poured into the distillation pot, and the gasoline fractionation section is collected at 40-190°C, and the diesel fractionation section is at 250-330°C. The oil recovery rate is 70%. The purity by HPLC was 99.4%.

[0041] Example 2: Using Catalyst-2 to Crack Papermaking Waste Residue
[0042] Dry the papermaking waste residue (waste plastic) to make the water content less than 5%, crush it, feed it evenly into the fluidized bed cracking kettle, and crack it at 500°C under the action of Catalyst-2 (1%), catalytic cracking for 10 hours, the The fuel oil components are poured into the distillation pot, and the gasoline fractionation section is collected at 40-190°C, and the diesel fractionation section is at 250-330°C. The oil recovery rate is 75%. The purity by HPLC was 99.6%.
