Abstract
The present invention relates to a method for preparing basic oil of lubricating oil from cracked oil of waste plastics. The cracked oil produced by cracking waste plastics is subjected to polymerization in the presence of strong acid catalysts, such as aluminium trioxide and aluminium triisobutyl, the added amount of which is 1-6% of that of polymerization material, at temp. of normal temp. -1000 deg.C and pressure of ordinary pressure- 1.0 MPa with stirring for 1-8 h., to obtain basic oil of lubricating oil. Its yield is high, and at the same time it can greatly raise the quality of gasoline and diesel oil.
Description
The present invention relates to waste plastics recovery and utilize method, particularly the method for lubricating oil is made in waste plastics recovery.
In recent years, along with the widespread use of plastics, waste or used plastics is also along with rolling up, so the processing of plastic waste has become urgent problem, and the treatment process of plastic waste is to reclaim processing to make it become the inferior reworked material of matter at present, also has to reclaim to be processed into the oiling product.How the Treatment of Waste Plastics new technology is provided, improves Treatment of Waste Plastics products obtained therefrom class, plastic waste is processed into the higher product of using value, this is the problem that people need study.
Chinese patent: " the plastic waste polyolefine is made the method for hydrocarbon ils " this piece of writing is application on May 12nd, 1993, and on October 20th, 1993 is open, application number: 93104896.6.
" with making gasoline and diesel from waste plastics method and device " this piece of writing is application on July 23rd, 1991, and on February 10th, 1993 is open, application number: 91104875.8.
United States Patent (USP): 3956414; 4108730; 4175211; 4118281; 4851601; These patents of Japanese Patent: 0386790:0316891 are spoken of the problem of utilizing of plastic waste, and the product of making mostly is hydrocarbon ils such as paraffin, refinery coke, gasoline and diesel oil, and the base oil of making lubricating oil does not have.
The objective of the invention is to improve the class that waste or used plastics is handled products obtained therefrom, a kind of method that plastic waste is processed into the higher lubricant base of using value is provided.
The plastic waste that the present invention is used can be various not chloride waste plastic products, as waste polyethylene, waste polypropylene, useless poly-stupid ethene etc.Gasoline, the fraction of diesel oil of cracking waste plastics output are sent into paradigmatic system, add catalyzer under certain condition and carry out polymerization, go then to make with extra care, tell gasoline, diesel oil and lubricant base.
The cracking waste plastics oil bodying can be used the cracking vapour of lighting from fore-running, and fraction of diesel oil also can use vapour, fraction of diesel oil more than 80 ℃.It is lower that the doing of polymer raw should be controlled, general≤360 ℃.Polymerizing catalyst can be used strongly acidic catalyst, and as solid or liquid alchlor, triisobutyl aluminium etc., catalyst levels are counted the 1-6% of polymer raw usually with active princlple (alchlor).Cracking can be at normal pressure--carry out under the 1.0MPa, temperature is a normal temperature--100 ℃, time 1--8 hour.Polymerization technique can be intermittently or continous way.Industrial scale is less, and available single reactor can be used the successive reaction still when scale is big.Raw material is added in the reactor, and under agitation control reaction temperature is stable by above-mentioned processing condition, and after the catalyzer branch added several times, reaction was kept two hours again.Reaction ends, and sediment, (the black jelly of agent slag and the superimposed generation of part) are told in clarification.Clear liquid is made with extra care.Make with extra care and to adopt refining with adsorbents or washing to make with extra care.Washing is refining to require the long period dehydration to leave standstill, and oil contains less water after washing.When adopting refining with adsorbents, in clear liquid, add an amount of calcium hydroxide and atlapulgite, stirred 1--5 hour down, leach sediment, filtrate is distilled at 60--100 ℃.Industrial scale hour available still formula batch distillation can adopt the continuous still battery tower when scale is big, steams gasoline under normal pressure.Can steam diesel oil (opening side line) under the normal pressure to tower bottom blowing steam during continuous still battery, the tower bed material changes vacuum distillation tower over to, and lubricating oil is cut 2--3 fraction, is beneficial to modulate finished lube.Be difficult for blowing steam during batch distillation, normal pressure is received gasoline, from receiving diesel oil, decompression operation, determine that by the requirement of diesel oil zero pour it steams outlet temperature, as 150 ℃ of residual voltage 2mmHg can receive≤330 ℃ of fractions make diesel oil, after this slowly collecting 2--3 fraction (comprising still bottom oil) is lube cut usefulness.
Advantage of the present invention is that plastic waste is converted into than gasoline, the more high-grade lubricant base of diesel oil, and the gained lubricant base is light orange, and gasoline, diesel oil water-white are stable, not impurity such as sulfur-bearing nitrogen.
Below, one embodiment of the present of invention are described.
The cracked oil that makes with waste polypropylene woven bag and the cracking of waste polyethylene film, cutting is from initial boiling point--330 ℃ of fractions, liquid alchlor catalyzer with 3% (alchlor meter), at normal pressure-80 ℃, stir under 3 hours conditions, carry out polymerization, go refining and distilling to cut out gasoline, diesel oil then, stay lubricant base.The results are shown in Table 1:

Be aggregated under the normal pressure and carry out ,≤80 ℃ of fraction losses are so the material yield is low.
