Embodiment 1～5

[0072] Waste plastic A is a commercially available mixture mixed according to the ratio of PE:PP:PS:PVC=10:5:1:1.5, wherein PE, PP, and PVC are in the form of film, and PS is in the form of foam. Crushed to <50mm, the broken particles of waste plastic A and solvent I preheated to 65°C enter the first decontamination unit of waste plastic, and are fully mixed and dissolved at 65°C. °C separated into a first solution and a first solid mixture.

Embodiment 1

[0073] The solvent I used in Example 1 is tetrahydrofuran, and the weight ratio of solvent I to waste plastic A is 10:1; the chlorine content in the obtained first solid mixture is 23 μg / g.

Embodiment 2

[0074] The solvent I used in Example 2 is methyl ethyl ketone, and the weight ratio of solvent I to waste plastic A is 10:1; the chlorine content in the obtained first solid mixture is 25 μg / g.

Abstract

The invention relates to a method and system for producing vehicle fuel from waste plastic. The method comprises the steps that waste plastic sequentially passes through a first waste plastic impurity removal unit and a second waste plastic impurity removal unit for impurity removal reaction to obtain a second solution low in chlorine content and silicon content; and the second solution with low impurity content is fed into a catalytic cracking unit for catalytic cracking reaction to obtain vehicle fuel. The method is beneficial to solving the problem of white pollution, and the prepared vehicle fuel has good environmental benefits, social benefits and economic benefits.

Description

technical field [0001] The invention relates to the technical field of solid waste plastics treatment, in particular to a method and system for preparing vehicle fuel from waste plastics. Background technique [0002] According to statistics, the total amount of waste plastics in my country is about 1 billion tons and is gradually increasing at a rate of 40 million tons per year. It is estimated that by 2035, the world will generate about 8 billion tons of waste plastics. Waste plastics account for more than 15% of urban domestic waste. Taking Beijing Liulitun landfill as an example, it covers an area of ​​27 hectares, and the existing landfill volume is about 12 million tons, of which about 2 million tons of waste plastics. This not only causes serious environmental pollution, but even affects the ecological balance in the natural environment; it is also a serious waste of petrochemical resources. The existing waste plastics treatment technologies mainly include landfill,...
