Abstract
The invention which belongs to the refining field of the petrochemical industry especially discloses a method for preparing mixed oil from plastics and rubber. According to the method, the mixed oil is obtained by treating the waste plastics or rubber, a palladium catalyst, cyclohexylamine, N-methylmorpholine and diethyl DL-malate as raw materials, heating to 120-430DEG C, reacting for 1-4h, and heat decomposing. The method of the present invention which has the advantages of simple technology, easy operation, low cost, high product yield, full utilization of wastes, changing of wastes into valuables, and realization of resource recycle is helpful for environmental protection.
Description
(1) technical field
The invention belongs to petrochemical complex refining field, particularly a kind of method of utilizing plastics and rubber to produce mixing oil.
(2) background technology
At present, the treatment process of waste or used plastics and rubber mainly contained to landfill, granulation regeneration and cracking.Landfill is land occupation not only, and welding; Though the granulation regeneration can extend the work-ing life of waste or used plastics and rubber, after recycling, finally still bad processing; Cracking becomes gasoline, diesel oil by waste or used plastics, and patent applied for is multinomial.
Waste or used plastics and rubber cracking can be divided into thermo-cracking and catalytic pyrolysis two classes, thermo-cracking exists cracking temperature higher, generally at 600 ℃, scission reaction speed is slow, in cracking process, the side reactions such as aromizing, condensation, polymerization are stronger, splitting gas easy blocking pipe when condensation, affect quality product, and easily blast; Fuel consumption is large.The catalytic pyrolysis main drawback is that oil yield is low, and production cost is high, and the quality product difficulty is up to state standards.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides utilize plastics and the rubber that a kind of technique is simple, product yield is high to produce the method for mixing oil.
The present invention is achieved through the following technical solutions:
A kind of method of utilizing plastics and rubber to produce mixing oil, comprise the steps:
(1) plastic waste and rubber press cake processed are placed in cracking still;
Plastic waste and rubber are carried out to pre-treatment, change their original free-running properties and distribute, reduce after compression to take up room, convenient operation and interpolation.
(2) add palladium catalyst, hexahydroaniline, N-methylmorpholine and hydroxy-butanedioic acid diethyl ester in cracking still, be heated to 120 ~ 430 ℃, react 1 ~ 4h;
(3) connecting refrigerating unit in the outlet of cracking still carries out cooling to material; In refrigerating unit;
The inlet temperature of water coolant≤40 ℃, temperature out≤45 ℃, the inlet temperature of material is 120 ~ 430 ℃, temperature out is 50 ~ 55 ℃.
(4) cooled material enters holding tank through purification system, and purification medium was filter sand or gac.
For reducing production costs, purification medium selected the possibility of filter sand larger.
The weight proportion of described plastic waste and rubber, palladium catalyst, hexahydroaniline, N-methylmorpholine and hydroxy-butanedioic acid diethyl ester is 198:0.015 ~ 0.02:0.01 ~ 0.03:0.02 ~ 0.025:0.03 ~ 0.07.
For preventing that the sulphur in waste or used plastics and rubber is converted into sulfurous gas polluted air environment, the tail gas discharged in described cracking still is through alkali liquor absorption, for waste gas is processed.
Simple process of the present invention, easily operation, cost is low, product yield is high, take full advantage of refuse, turns waste into wealth, and has realized resource reutilization, contributes to protection of the environment.
