Abstract
The present invention relates to a method for producing vaseline by using waste and old plastics, which is characterized in that after the waste and old plastics are cleaned, catalyst is added into the plastics to carry out cracking reaction; after gas and liquid which are generated by the cracking process are pumped out by negative pressure, the gas and the liquid are directly filtered to be discolored, and then, the gas and the liquid are cooled to form the vaseline after filtered. The method of the present invention has the advantages of low cost of raw materials, simple technology, low production cost, etc.
Description
The present invention goes on foot and be a kind of is the method for raw material production Vaseline with the waste or used plastics.
At present, Vaseline be by in the process of oil production to pay a product be raw material through refining forming repeatedly.This method is with the product of paying in its process of oil production, the throw out that generates after cooling off such as oil residues after the crude distillation of paraffin wax base; It two is throw outs in the petroleum storage tanks; Three to be locomotive oils handle resistates through solvent recuperation with solvent dewaxed for it; Its four are production premium motor fuel concentrated things of paying product etc. for raw material through heating, remove lower boiling oil, by activated carbon or atlapulgite, removal of impurities, decolouring, deodorizing etc. are refined repeatedly and are formed.This method existence repeats operations such as heating, decolouring, removal of impurities, causes complex process, shortcomings such as energy consumption height.
The objective of the invention is with the waste or used plastics is raw material, produces the method for Vaseline, and it is low that this method has a cost, product yield height, advantage such as technology is simple.
The object of the present invention is achieved like this.Waste or used plastics after handling, is dropped into reactor in cleaning, add ripe, behind the catalyzer such as lime or atlapulgite or activated carbon, the cracking of heating, its cracking temperature is controlled at 320 ℃ to 480 ℃, the gas that institute's cracking generates is extracted reactor out with vacuum, its negative pressure is controlled at 0.04 to 0.12 normal atmosphere, the gas-liquid process that vacuum is extracted out is filtered, after decolouring by the decolorizer that is equipped with catalyzer such as gac or atlapulgite, filter again, promptly make the Vaseline product after the cooling.
Below in conjunction with embodiment the present invention is further described.
After waste or used plastics cleaned, drop into tubular type scission reaction still, add white lime or catalyzer such as atlapulgite or activated carbon, with fiery reacting by heating still, temperature is controlled between 320 ℃ to 480 ℃, make its plastic cracking, take out method with the fast reactor that detaches of splitting gas with vacuum, its negative pressure is controlled between 0.04 to 0.12 normal atmosphere, the gas-liquid of its extraction is directly filtered through filtering net, the decolorizer that the gas-liquid of handling after filtration is transported to gac or atlapulgite carries out filtration treatment by filter cloth after decolouring and handling again, promptly makes the Vaseline product after the cooling; Lower boiling liquid still when gaseous state, is drawn in the pressure-pot and must pays product, solvent oil, detergent use oil.The gas that can not liquefy then in the suction gas tank, must pay product big right gas at normal temperatures.
Its principal reaction is as follows:
1. use the polyethylene waste material:
Number is less than rare hydrocarbon of 24, alkane, and wherein n is a carbonatoms in the macromolecular compound polyethylene, n
1It is 22 to 32 number.
2. use the polypropylene waste material
Atomicity is less than 24 rare hydrocarbon, alkane.
N wherein
2Be carbonatoms n in the macromolecular compound polypropylene
3It is 7 to 11 number.
According to detection: the yield of producing Vaseline with the polypropylene waste or used plastics reaches (48-63) %); The yield of producing Vaseline with vinyon reaches (74-82) %.
The present invention is because the employing waste or used plastics is a raw material, and its raw material sources are extensively inexpensive, and by the hot gas that directly utilizes cracking to go out, liquid takes off by decolouring, filter, making, removal of impurities is once finished, thereby technology is simple, and production cost is low.Utilize negative pressure and add catalyzer, the yield of its Vaseline and quality are guaranteed.Improved the efficient of Vaseline.
Claims (1)
1. utilize the method for waste or used plastics for raw material production Vaseline, it is characterized in that waste or used plastics after cleaning is handled, drop into reactor, after adding white lime or atlapulgite or activated carbon catalyst, the cracking of heating, its cracking temperature is controlled at 320 ℃ to 480 ℃, the gas that institute's cracking generates is extracted reactor out with vacuum, its negative pressure is controlled at 0.04 to 0.12 normal atmosphere, the gas-liquid that vacuum is extracted out is after filtering, after decolouring by the decolorizer that is equipped with catalyzer such as activated carbon or atlapulgite, filter again, promptly make the Vaseline product after the cooling.
