3) Sanitary landfill treatment, waste plastic landfill is the treatment method with the least added value, which not only wastes the recycling value of waste plastic, but also occupies a large area of ​​land resources. In addition, sanitary landfill treatment still requires certain safety technologies
4) Heat recovery by incineration. Waste plastic is a fuel with high calorific value. Waste plastic recovery of heat by incineration is a high value-added treatment method, but the problem of secondary pollution must be properly handled
PC can be used as door and window glass, and PC laminates are widely used in protective windows in banks, embassies and public places, for aircraft canopies, lighting equipment, industrial safety baffles and bulletproof glass. So far, discarded PC has not been adopted internationally Relevant reports on resin synthesis of naphthenic hydrocarbons in aviation kerosene range

Embodiment

[0036] 1. Investigate the reactivity of polycarbonates under various reaction conditions during alcoholysis.

[0037] 1.1 The effect of reaction temperature on polycarbonate alcoholysis process. Reaction conditions: 1g polybisphenol A carbonate, 40g methanol, reaction time: 3.5h. see table 1

[0038] Table 1. Different reaction temperatures

[0039]

[0040] As can be seen from Table 1, as the reaction temperature increases, the conversion rate of bisphenol A polycarbonate gradually increases, and the yield of bisphenol A also gradually increases until reaching the highest at 180 degrees.

[0041] 1.2 The influence of reaction time in polycarbonate alcoholysis process. Reaction conditions: 1g polybisphenol A carbonate, 40g methanol, reaction temperature: 180°C. see table 2

[0042] Table 2. Different reaction times

[0043]

[0044]

[0045] As can be seen from Table 2, with the increase of the reaction time, the yield of bisphenol A gradually increased, but no ...

Abstract

The invention relates to a method for synthesizing cyclic hydrocarbon in aviation kerosene from a polycarbonate compound-containing material. A purpose of the invention is to solve the defect of low density of biomass aviation fuel obtained in the prior art. In the prior art, plastics, plates and glass made of waste polycarbonates are low in cost, and the plastics and the glass made of waste polycarbonates have great threat to the environment as white garbage. According to the invention, the method solves the problem of aviation fuel to a certain extent, solves the environmental problem causedby white pollution, and has potential advantages in future industrial application.

Description

technical field [0001] The invention relates to a method for directly converting waste polycarbonate-made plastics, plates and glass into cyclohydrocarbons in the range of aviation kerosene. It specifically includes two steps: 1) Mix plastics, plates, and glass made of waste polycarbonate with alcohol and then alcoholyze them at high temperature to obtain aromatic diols; 2) Hydrodeoxygenate the aromatic diols generated in step 1 get C 13-15 of alkanes. This is the first report on the direct conversion of plastics, plates, and glass made of waste polycarbonate into aviation fuel. Compared with traditional aviation fuel, its source of raw materials is cheap and easy to obtain, and plastics made of waste polycarbonate in life , the glass can be used directly without pretreatment. Background technique [0002] Environmental problems such as the dwindling of fossil resources and the large amount of greenhouse gas emissions caused by the combustion of fossil energy are becoming...
