The present invention relates to a method for treating waste oil, waste oil, etc., and more specifically, it involves dispersing powdered norbornene-based polymer in water containing alcohol to form a slurry, which is then suspended on the surface of water or seawater. The present invention relates to a method for removing or recovering oil added to oil. When norbornene polymer powder comes into contact with various oils, it easily absorbs oil and forms an agar-like (gel-like) thin film. Furthermore, since this thin film has sufficient strength, it has the characteristic that various recovery methods can be used. Conventionally, utilizing the above-mentioned properties of norbornene-based polymer powder, norbornene-based polymer powder has been directly applied to surfaces where oil is floating, for the purpose of absorbing and removing waste oil and waste oil from the surface of water, seawater, etc. A method has been proposed for spraying the
128263). However, although the polymer is lighter than water or seawater and floats on the water surface, it does not disperse in water or seawater, so it absorbs oil on the surface of water or seawater, but absorbs oil dispersed in water or seawater. As a result, the oil absorption efficiency is poor and is not completely satisfactory. The present inventors have arrived at the present invention as a result of repeated studies to improve the above-mentioned drawbacks. An object of the present invention is to provide an oil removal or recovery method that is easy to handle and has improved oil absorption efficiency. This is achieved by adding the same to water or oil floating on the surface of seawater. Since the method of the present invention can absorb not only oil above the water surface but also below the water surface (dispersed in water), it is an oil removal or recovery method with excellent oil absorption efficiency. The norbornene polymer used in the present invention easily absorbs large amounts of solvents (toluene, benzene, xylene, etc.) and various oils (A to C heavy oil, spindle oil, machine oil, light oil, kerosene, gasoline, etc.) even at room temperature. It is a ring-opening polymer or copolymer of bicyclo(2,2,1)heptene-2 or its derivatives, which has the property of becoming agar-like (gelling). It is a polymer obtained by polymerizing with etc.
The monomers used are bicyclo(2,2,
1) Heptene-2, methyl-5-bicyclo(2,
2,1) Alkyl-5 such as heptene-2, ethyl-5-bicyclo(2,2,1)heptene-2
-bicyclo(2,2,1)heptene-2 monomer, methoxy-5-bicyclo(2,2,1)heptene-2, ethoxy-5-bicyclo(2,2,
1) Alkoxy-5-bicyclo(2,2,1) heptene-2 monomers such as heptene-2, cyano-5-bicyclo(2,2,1) heptene-2, bicyclo(2,2,1 ) Heptene-2-5 carboxylic acid ester monomer, bicyclo(2,2,1)
Examples include diester monomers of heptene-2-5 and 6-dicarboxylic acids and mixtures thereof. A typical polymer is bicyclo(2,2,1)
Examples include polynorbornene, which is a ring-opened polymer of heptene-2. In order to achieve the object of the present invention, the norbornene-based polymer must be in powder form, and one that has been dried into powder form in a drying step after completion of polymerization is particularly suitable. Further, the particle size of the powder is particularly preferably about 0.01 to 1 mm. The alcohols used in the present invention are not subject to any restrictions as long as norbornene polymer powder is dispersed in water to form a slurry, and examples include methyl alcohol, ethyl alcohol, propyl alcohol, butyl alcohol, pentyl alcohol, and hexyl alcohol. Monohydric aliphatic saturated alcohols such as allyl alcohol, monohydric aliphatic unsaturated alcohols such as allyl alcohol, monohydric cycloaliphatic alcohols such as cyclopentanol, monohydric aromatic alcohols such as benzyl alcohol, furfuryl alcohol Monohydric heterocyclic alcohols such as, dihydric alcohols such as glycol, trihydric alcohols such as glycerin, and sugar alcohols of tetrahydric or higher valence can be used alone or in combination, but the preferred alcohols are monohydric aliphatic alcohols. It is a saturated alcohol. There is no restriction on the amount of alcohol added to water as long as the powdered norbornene polymer is dispersed in a slurry form, but it is usually at least 1% by weight, preferably at least 5% by weight of the norbornene polymer used. , more preferably 10% by weight or more. The concentration of the polymer is not limited in any way and can be appropriately determined in consideration of the amount of oil, oil absorption efficiency, and ease of handling. Moreover, alcohols can be used in combination with surfactants. The method for preparing the slurry of norbornene-based polymer powder of the present invention is not limited at all, and examples include a method of dissolving alcohol in water and adding powdered norbornene-based polymer to this aqueous solution to form a slurry with stirring; Examples include a method of spraying the polymer powder onto the polymer powder and then dispersing it in water to form a slurry, or a method of impregnating the polymer powder with an alcohol and dispersing it in water to form a slurry. In the method of the present invention, the norbornene-based polymer in the form of a slurry may be sprayed onto the surface of water or seawater in which oil is suspended by an appropriate means, and brought into contact with the oil. Spraying method,
For example, a method of spraying from a nozzle under pressure can be used. The thin film of norbornene-based polymer that absorbs oil, swells, and becomes an agar-like gel has sufficient strength and does not break into pieces due to wave action, making it suitable for conventional collection methods such as net collection and suction pump collection. method. The method of the present invention uses an oil absorbent in the form of a slurry, so it is easy to handle, absorbs oil above and below the water surface, turns it into a gel, reduces the harmfulness of the oil, and removes oil from water, seawater, etc. It can be said to be an excellent method of absorbing oil that makes it easier to absorb oil. The present invention will be specifically explained below using Examples. Example Norbornene polymer powder (product of CdF, France)
NORSOREX, particle size 0.01-1mm) 20g and 8g of alcohols listed in Table 1 (first-class reagent manufactured by Wako Pure Chemical Industries, Ltd.)
was added, and after thorough stirring, the entire amount was dispersed in 100 c.c. of water to prepare a slurry of the polymer. In a 500c.c. beaker, add 200c.c. of water and aromatic oil (Nippon Sunoil Co., Ltd. product Sundex790, viscosity SUS/38
℃, 3500), and to this add the entire amount of the above slurry or 20g of norbornene polymer powder.
was added and stirred for 2 minutes. After being left at room temperature for 24 hours, the oil absorption state was visually judged and the results shown in Table 1 were obtained. From the results in Table 1, it was found that the method of the present invention absorbs almost all of the oil above and below the water surface, whereas the conventional method of adding norbornene polymer powder absorbs only the oil above the water surface. The same experiment as above was conducted using B heavy oil as the oil, but the results were exactly the same as those listed in Table 1.
