Abstract

By using the environment protection technique. Waste polyethylene is cracked into wax under appropriate condition so that the white pollution caused by the waste polyethylene product is thoroughly solved, and the passive output-type garbage treatment is changed into the profit-created waste plastics treating industry.

Description

Process for preparing wax from waste polyethylene
Present technique is a green technology
Present technique is a kind of method that the waste polyethylene product at high temperature is cracked into wax.Polyethylene at high temperature can be cleaved into hydrocarbon gas, liquid hydrocarbon and solid hydrocarbons; Control different cracking conditions, can produce different products.Present technique is to have found a kind of approach that can make the very big utility value of waste polyethylene performance---produce wax.
Find one of the prior art of reference role by retrieval: number of patent application is: 92109462, and preparation can form the method for the polyethylene wax of milk sap in water.The product of this method is different with present technique, and method is also different, its usefulness be " intensification air oxidation process ", be " high-temperature cracking method " and present technique is used.
Present technique causes " white pollution " for thorough improvement by polyethylene products and invents; Become passive investment and be treated to the type refuse treatment industry of making profits.Turn waste into wealth, benefit the nation and the people.
Waste polyethylene put into have the reactor that cools back receiving apparatus, be warming up to 430 ℃, insulation is at 410 ℃-440 ℃.When treating that distillate reaches 5% (volume), stop heating, cooling.Treat that emitting product after the product temperature is lower than 200 ℃ is wax, productive rate reaches 93%-95%.
Present technique technology is simple, and facility investment is few, is easy to promote.
