[0069] Example

[0070] The following examples are given to more specifically describe the embodiments of the present application. Various tests and evaluations were performed according to the following methods. In addition, unless otherwise specified, "parts" and "%" are based on mass.

[0071] Calculation of conversion rate

[0072] Conversion rate = 100% - the number of moles of the remaining mixed waste plastics / the number of moles of the input mixed waste plastics × 100%;

[0073] Among them, for a single type of plastic, the molar number is the molar number corresponding to the monomer of its polymer. During the experiment, the mixed waste plastics were weighed separately for each plastic and then mixed. The molar number of mixed waste plastics put into the mixed waste plastics was the sum of the molar numbers of several plastics put in, and the molar number of the remaining mixed waste plastics was the sum of the molar numbers of several plastics remaining after degradation was completed.

[0074] Calculation of output

[0075] During the degradation reaction, a gas collector is used to collect gas from the reactor outlet pipe, and the gas is detected by the flame ionization detector (FID) and thermal conductivity detector (TCD) in the gas chromatograph. The product yield is calculated by the chromatographic peak area and the corresponding response factor of the product, as well as the argon (Ar) internal standard response factor. Taking methane as an example: n(CH4) is the amount of methane, n(Ar) is the amount of Ar (injected into the gas chromatograph at the same time as methane); X(CH4) is the relative response factor of methane, and X(Ar) is the relative response factor of Ar:

[0076]

[0077] Calculation of yield

[0078] The yield is the ratio of the actual output of the product obtained from a unit amount of mixed waste plastics to the theoretically calculated maximum output of the product obtained from a unit amount of mixed waste plastics.

[0079] Taking CH4 as an example, CH4 yield = actual CH4 mole number obtained / theoretical maximum CH4 mole number × 100%; wherein, the theoretical maximum CH4 mole number is the mole number of carbon atoms in the mixed waste plastics.

[0080] The structure of the device for degrading plastics used in the following embodiments is as follows:

[0081] The solar photovoltaic conversion system consists of two 1.0m×0.5m square ethylene-tetrafluoroethylene copolymer (ETFE) flexible solar panels (Dongguan Kupa Technology Co., Ltd., model KUPA-100W; peak power 100W); the ETFE flexible solar panels are equipped with automatic light chasers (Shenzhen Taoyouqu Technology Co., Ltd., model A1), which realize the light chasing function of the solar panel through photoresistors, computer programs and motors; the solar photovoltaic conversion system is connected to a transformer (Guangzhou Changji Electronics Co., Ltd., model 2000W), and the transformer is respectively connected to a gas generator (Shanghai Aikun Instrument Equipment Co., Ltd., model AK-H300), a reaction control system (MEACON, model MIK-200D, 6 channels) and a battery (60Ah / 4400W outdoor battery, Dongguan Kupa Technology Co., Ltd.); the reactor is a cylindrical glass tube with an inner diameter of about 1.5cm, with an air inlet pipe and an air outlet pipe on the top, the air inlet pipe is connected to the gas generator, the air outlet pipe is connected to the gas collector, a pressure control valve is arranged on the air inlet pipe, and a back pressure valve is arranged on the air outlet pipe; the reaction control system connects the pressure control valve, the reactor and the focusing device; the focusing device includes a focusing mirror and an adjustment module, the focusing mirror is a Fresnel lens (Meiying Technology, size 1.1m×1.1m, focal length 620mm), and the adjustment module is temperature-controlled by a total solar irradiance sensor (Shandong Jianda Renke Electronic Technology Co., Ltd., RS-RA-*-JT) to keep the reactor temperature in a relatively stable range as much as possible.

[0082] Performance evaluation of a device for degrading plastics

[0083] After field testing, it was found that the above-mentioned plastic degradation device can output a maximum electrical power of about 200W, which is sufficient to drive the gas generator (rated power 100W) and the reaction control system (rated power 50W) with a large margin, and can achieve self-sustaining operation.

[0084] The focusing heat generation performance of the focusing device under actual sunlight was evaluated below, and the results are shown in Table 1 below.

[0085] Table 1 Concentrating heat generation capacity of concentrating devices under different sunlight intensities

[0086]

[0087] As can be seen from Table 1, the sunlight intensity is between 410-620 W·m -2 , the reactor temperature can reach 250-360°C, indicating that the light concentrator of the present application has a strong light concentrating heat generating capability. Moreover, the inventors found during the test that the reactor of the present application can maintain a constant temperature for a certain period of time.

[0088] Example 1

[0089] 0.8g polyethylene, 0.8g polypropylene, 0.2g polyvinyl chloride, and 0.4g catalyst Ni / Al2O3 were mixed and loaded into the reactor. The solar photovoltaic conversion system was turned on to supply the generated electricity to the gas generator and the reaction control system. The hydrogen generated by the gas generator through the electrolysis of water entered the reactor from the reactor's air inlet pipe for hydrogenolysis reaction. The reaction control system controlled the temperature of the reactor by controlling the angle of the condenser or the distance between the condenser and the reactor; the reaction control system controlled the flow rate of hydrogen entering the reactor to 20mL / min; the reaction was continued for 7 days, and 1787mg CH4 and 113mg HCl were collected in the gas collector after 7 days; the CH4 yield was 87%, and the HCl yield was 98%. The specific parameters and results are shown in Table 2.

[0090] Example 2

[0091] 2g polyethylene and 2g polypropylene were mixed with 1.0g catalyst Ni / Al2O3 and loaded into the reactor. The solar photovoltaic conversion system was turned on to generate electricity to supply the gas generator and the reaction control system. The nitrogen generated by the gas generator entered the reactor from the air inlet of the reactor for pyrolysis reaction. The reaction control system controlled the temperature of the reactor by controlling the angle of the condenser or the distance between the condenser and the reactor. The reaction control system controlled the flow rate of hydrogen entering the reactor to be 20mL / min. The reaction was continued for 7 days. After 7 days, 1318mg C3-C 10 Alkanes and 2244 mg C6-C 10 Aromatics; C3-C 10 The alkane yield was 33%, C6-C 10 The aromatics yield was 61.1%. Specific parameters and results are shown in Table 3.

[0092] Since solar energy is the only energy source for the plastic degradation device of the present application, the intensity of sunlight has a great influence on the reaction effect of the plastic degradation device of the present application on degrading plastic. Examples 1 and 2 of the present application tested the degradation and conversion of waste plastics by the plastic degradation device under different sunlight intensities, and the results are shown in Tables 2 and 3.

[0094]

[0095]

[0096] Note: “-” in Table 2 means no corresponding parameter.

[0097] The inventors found in the study that when the light intensity is high, the reactor can be heated to above 350°C, while when the light intensity is low, the temperature of the reactor can only be heated to about 270-290°C. As can be seen from Table 2, the plastic degradation device of the present application can achieve effective conversion of waste plastics: when the light intensity is high, a higher yield of CH4 and HCl can be obtained, and when the light intensity is low, the yield of CH4 and HCl is slightly lower. After 7 days of operation, 1.8g of waste plastics are completely converted to produce 1787mg of CH4 and 113mg of HCl, achieving a CH4 yield of more than 80% and a HCl yield of more than 95%.

[0099]

[0100] Note: “-” in Table 3 means no corresponding parameter.

[0101] The inventors found that the reaction control system can control the angle of the condenser or the distance between the condenser and the reactor to control the temperature of the reactor to 250-350°C, and different proportions of C3-C 10 Alkanes and C6-C 10 Aromatic hydrocarbons. At 250℃-300℃, the alkane yield is relatively high, and the alkane: aromatic hydrocarbon carbon number ratio is about 0.8-1:1; at 300℃-350℃, the aromatic hydrocarbon yield is relatively high, and the alkane: aromatic hydrocarbon carbon number ratio is about 0.6-0.7:1. As can be seen from Table 3, the plastic degradation device of the present application can effectively transform waste plastics: when the light intensity is high, a high yield of C3-C 10 Alkanes and C6-C 10 Aromatic hydrocarbons; when the light intensity is low, the C3-C 10 Alkanes and C6-C 10 The yield of aromatics was slightly lower. After 7 days of operation, 4 g of waste plastic was completely converted to produce 1318 mg of C3-C 10 of alkanes and 2244 mg of C6-C 10 Aromatic hydrocarbons have achieved a waste plastic conversion rate of more than 95%.
