Embodiment 1

[0026] Example 1: Preparation of Catalyst-1

[0027] Take commercially available SnCl 4 ·5H 2 O 20g and 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 was added with stirring to adjust the pH to 8, aged at room temperature for 24 hours, filtered by suction, and subjected to 2% ammonium acetate solution Wash to remove Cl - (Use 0.1 mol / L AgNO 3 Test), the filter cake was dried at 100°C for 24h, ground 100 mesh, and placed in 1mol / L (NH 4 ) 2 S 2 O 8 Soak in the solution (15 mL / g), then filter, dry, and roast at 550°C for 5 hours to obtain the S 2 O 8 2- / SnO 2 -Fe 2 O 3 Catalyst (Fe / Sn molar ratio is 1:9).

Embodiment 2

[0028] Example 2: Preparation of Catalyst-2

[0029] Get SnCl from the market 4 ·5H 2 O 20g and 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 was added with stirring to adjust the pH to 9, aged at room temperature for 48h, filtered, filtered through 2% ammonium acetate solution Wash to remove Cl - (Use 0.1 mol / L AgNO 3 Test), the filter cake is dried at 100℃ for 24h, ground 100 meshes, placed in 2 mol / L H 2 SO 4 Soak in the solution (15 mL / g), then filter, dry, and roast at 600°C for 3 hours to obtain the SO 4 2- / SnO 2 -Fe 2 O 3 Catalyst (Fe / Sn molar ratio is 1:4).

Embodiment 3

[0030] Example 3: Preparation of Catalyst-3

[0031] Get SnCl from the market 4 ·5H 2 O 20g and FeCl 3 ·6H 2 O 2.51g (produced by Sinopharm Chemical Reagent Co., Ltd.) was dissolved in 200 mL of distilled and stirred, and 25% (w / w) ammonia was added to adjust the pH to 8, aged at room temperature for 12 hours, filtered by suction, and washed with 2% ammonium acetate solution. Cl - (Use 0.1 mol / L AgNO 3 Test), the filter cake was dried at 100°C for 24h, ground 100 meshes, and placed in 2mol / L (NH 4 ) 2 S 2 O 8 Soaked in the solution (15 mL / g), then filtered, dried, and roasted at 550°C for 8 hours to obtain the S 2 O 8 2- / SnO 2 -Fe 2 O 3 Catalyst (Fe / Sn molar ratio is 1:6).

Abstract

The invention dislcoses a solid super acidic catalyst for waste plastic catalytic pyrolysis as well as a manufacture method and an application thereof, which aims at solving the problems that papermaking waste slag generated by the waste paper recovery reutilization can not be effectively utilized, and the huge pressure is caused on the environment. The solid super acidic catalyst is transition metal modified tin system solid super acidic, and the expression formula of the transition metal modified tin system solid super acidic is one of the following expression formulas: SO4<2-> / SnO2-Fe2O3, S2O8<2-> / SnO2-Fe2O3, SO4<2-> / SnO2-ZnO, S2O8<2-> / SnO2-ZnO, O4<2-> / SnO2-TiO2 and S2O8<2-> / SnO2-TiO2. The solid super acidic catalyst has the advantages that the production cost is low, the manufacture is easy, and waste plastics of main ingredients of the papermaking waste slag can be effectively prepared into fuel oil through the catalytic pyrolysis.

Description

technical field [0001] The invention relates to a catalyst, in particular to a solid superacid catalyst for catalytic cracking of waste plastics and its manufacturing method and application. Background technique [0002] Waste paper recycling is an effective way to solve the shortage of raw materials for papermaking. It can save resources and reduce costs. It is an important measure for my country's paper industry to solve the problem of fiber raw materials. However, a large amount of waste residue will be produced after utilizing waste paper to make paper. The production and sales of hundreds of paper mills in Fuyang City, Zhejiang Province account for more than 60% of the domestic market. According to statistics, more than 2,000 tons of waste residues are generated every day. After analysis, the main component of waste residues is waste plastics, and the annual waste plastics production is 151,200 tons. Because plastic waste is not perishable, it seriously affects the eco...
