Description
Olje for anvendelse ved gjenvinning av gummi fra gummi-avfall. Oil for use in the recovery of rubber from rubber waste.
Foreliggende oppfinnelse angår en re-genereringsolj e som primært er egnet for regenerering av syntetisk eller naturlig gummi. The present invention relates to a regeneration oil which is primarily suitable for the regeneration of synthetic or natural rubber.
En gummiregenereringsolje ifølge oppfinnelsen omfatter (A) en blanding av alkylbenzener og (B) en blanding av alkylnaftalener, hvor oljen har et anilinpunkt på mindre enn 15° C. Denne regenereringsolje er først og fremst egnet for regenerering av naturlig eller syntetisk styrenbutadien-gummi eller en blanding derav. A rubber regeneration oil according to the invention comprises (A) a mixture of alkylbenzenes and (B) a mixture of alkylnaphthalenes, where the oil has an aniline point of less than 15° C. This regeneration oil is primarily suitable for the regeneration of natural or synthetic styrene-butadiene rubber or a mixture thereof.
Blandingens bestanddel A, dvs. en The mixture's component A, i.e. a
blanding av alkylbenzener, har vanligvis et begynnelseskokepunkt på minst ca. 130° C. Det foretrekkes imidlertid at blandingen av alkylbenzener har et vidt kokeområde, f. eks. mellom 130° C og 300° C. mixture of alkylbenzenes, usually has an initial boiling point of at least approx. 130° C. However, it is preferred that the mixture of alkylbenzenes has a wide boiling range, e.g. between 130° C and 300° C.
Egnede alkylbenzener er ethylbenzen, xylenene, isopropylbenzen, trimethylben-zenene, tertbutyl-benzen, 1,2,3,4-tetrame-thylbenzen og andre høyere mono- og po-ly-alkylerte benzener. En særlig vel egnet blanding av alkylbenzener er blitt funnet å være en blanding som har et begynnelseskokepunkt mellom 160° C og 165° C, et sluttkokepunkt mellom 270 og 275° C, 20 volpst. avdestillerende under kokning mellom 185 og 190° C, 50 volpst. mellom 205 og 215° C og 90 volpst. mellom 250 og 255° C. En slik blanding omfatter butyl- og høy-ere alkyl-benzener og tri- og tetra-methyl-og tri- og tetr a -høyere alkylbenzener. Det blandete anilinpunkt for en slik blanding er ca. 24° C. Suitable alkylbenzenes are ethylbenzene, xylenes, isopropylbenzene, trimethylbenzenes, tertbutylbenzene, 1,2,3,4-tetramethylbenzene and other higher mono- and poly-alkylated benzenes. A particularly suitable mixture of alkylbenzenes has been found to be a mixture having an initial boiling point between 160°C and 165°C, a final boiling point between 270 and 275°C, 20 volpst. distilling while boiling between 185 and 190° C, 50 volpst. between 205 and 215° C and 90 volpst. between 250 and 255° C. Such a mixture includes butyl and higher alkyl benzenes and tri- and tetra-methyl and tri- and tetra-higher alkyl benzenes. The mixed aniline point for such a mixture is approx. 24° C.
Blandingen av alkylbenzener fremstilles fortrinnsvis ved ekstraksjon fra kerosen med flytende svoveldioxyd. I denne prosess behandles kerosen med det flytende svoveldioxyd f. eks. i et fyllt tårn. Svovel-dioxydet oppløser de aromatiske bestanddeler fra raffinatet som fjernes som topp-skikt. Bunnskiktet, dvs. ekstraktet, inne-holder den ønskede blanding av alkylbenzener som kan erholdes derav etter fjernelse av eventuelt oppløst S02, f. eks. ved avdampning. Alkylbenzener og blandinger av alkylbenzener kan også fremstilles ved de konvensjonelle metoder, dvs. ved om-setning av benzen med et alkyleringsmiddel som f. eks. et olefin eller alkylhaloge-nid i nærvær av en katalysator såsom fos-forsyre, svovelsyre, aluminiumtriklorid eller særlig flussyre eller bortrifluorid. Det ønskede alkylerte benzen eller -benzener kan erholdes ved destillasjon av reaksjons-blandingen, etter fraskillelse av eventuelt ureagert benzen og/eller alkyleringsmiddel som destillerer over først. The mixture of alkylbenzenes is preferably prepared by extraction from the kerosene with liquid sulfur dioxide. In this process, the kerosene is treated with liquid sulfur dioxide, e.g. in a filled tower. The sulfur dioxide dissolves the aromatic components from the raffinate, which is removed as a top layer. The bottom layer, i.e. the extract, contains the desired mixture of alkylbenzenes which can be obtained therefrom after removing any dissolved SO2, e.g. by evaporation. Alkylbenzenes and mixtures of alkylbenzenes can also be prepared by the conventional methods, i.e. by reacting benzene with an alkylating agent such as, for example an olefin or alkyl halide in the presence of a catalyst such as phosphoric acid, sulfuric acid, aluminum trichloride or especially hydrofluoric acid or boron trifluoride. The desired alkylated benzene or benzenes can be obtained by distillation of the reaction mixture, after separation of any unreacted benzene and/or alkylating agent which distills over first.
Blandingenes bestanddel B, dvs. en blanding av alkylnaftalener, har fortrinnsvis et ganske vidt kokeområde, f. eks. mellom 175° C og 325° C. Egnede alkylnaftalener innbefatter a- og (5-monomethyl- og ethyl-natfalener, 1,2-, 1,6-, 1,7- og 2,6-dimethylnaftalener, trimethylnaftalenene og acenaftalen. En særlig vel egnet blanding av alkylennaftalener erholdtes ved termisk krakking av nafta, hvilket ga en kompleks blanding av produkter som var gassformige ved den høye operasjonstemperatur, avbrytning av re-aksjonene ved tilsetning av vann og ad-skillelse i en gassformig og en tung væske-formig fraksjon, som deretter destilleres under oppnåelse av den ønskede blanding omfattende alkylnaftalener som væskefor-mig destillat. Denne blanding omfattet a-og p-monomethylnaftalener, 1,2- og 1,6- og 1,7-, 2,6-dimethylnaftalener, trimethyl-naftalener, acenaftalen samt fluoren og ca. 20 pst. naftalen. Dens begynnefseskoke-punkt var 160° C, og dens anilinpunkt var under —15° C. Alkylnaftalener kan også fremstilles ved de konvensjonelle metoder for alkylering av aromatiske forbindelser, eksempelvis kan a-methylnaftalen synteti-seres f. eks. ved Wurtz — Fittig-reaksjonen mellom a-bromnaftalen, methyljodid og natrium. The mixture's component B, i.e. a mixture of alkylnaphthalenes, preferably has a fairly wide boiling range, e.g. between 175° C and 325° C. Suitable alkylnaphthalenes include α- and (5-monomethyl- and ethyl-naphthalenes, 1,2-, 1,6-, 1,7- and 2,6-dimethylnaphthalenes, the trimethylnaphthalenes and acenaphthalene. A particularly suitable mixture of alkylene naphthalenes was obtained by thermal cracking of naphtha, which gave a complex mixture of products which were gaseous at the high operating temperature, interruption of the reactions by the addition of water and separation into a gaseous and a heavy liquid form fraction, which is then distilled to obtain the desired mixture comprising alkyl naphthalenes as a liquid distillate. , trimethyl-naphthalenes, acenaphthalene as well as fluorine and about 20 percent naphthalene. Its initial boiling point was 160° C, and its aniline point was below -15° C. Alkylnaphthalenes can also be prepared by the conventional methods for alkylating aromatic compounds, for example can a-methylnaphthalene are synthesized, e.g. by the Wurtz — Fittig reaction between a-bromonaphthalene, methyl iodide and sodium.
Skjønt naftalen også kan være tilstede i blandingen av alkylnaftalen, foretrekker man å begrense mengden derav til under ca. 20 vektpst., f. eks. ca. 10 vektpst. eller enridog lavere. Although naphthalene can also be present in the mixture of alkylnaphthalene, it is preferred to limit the amount thereof to less than approx. 20 wt., e.g. about. 10 wt. or even lower.
Hvis anilinpunktet for bestanddel A såvel som bestanddel B er under 15° C, kan forholdet mellom disse bestanddeler va-riere innenfor vide grenser. Hvis derimot den ene av bestanddelene skulle ha et anilinpunkt over 15° C, begrenses den maksi-male andel av denne bestanddel i den en-delige blanding ved at denne blandings analinpunkt må være lavere enn 15° C. Et meget hensiktsmessig forhold mellom bestanddel A og bestanddel B er blitt funnet å være ca. 30 : 70 på vektspasis, særlig når man bruker de ovenfor nevnte foretrukne blandinger av alkylbenzener og alkylnaftalener som henholdsvis bestanddel A og B. If the aniline point for component A as well as component B is below 15° C, the ratio between these components can vary within wide limits. If, on the other hand, one of the components should have an aniline point above 15° C, the maximum proportion of this component in the final mixture is limited by the fact that this mixture's aniline point must be lower than 15° C. A very suitable ratio between component A and component B has been found to be approx. 30:70 by weight, especially when using the above-mentioned preferred mixtures of alkylbenzenes and alkylnaphthalenes as components A and B, respectively.
Et vektsforhold mellom bestanddel A og bestanddel B på ca. 20 : 80 er også blitt funnet å være meget hensiktsmessig. Spe-sielt foretrukne forhold mellom bestanddel A og bestanddel B er derfor mellom ca. 15 : 85 og 35 : 65 på vektsbasis. Anilinpunktet for en olje er laveste temperatur for likevektsoppløsning av like volumdeler anilin og olje. Det blandede anilinpunkt er laveste temperatur for li-kevektsoppløsning av en blanding av to volumdeler anilin, én volumdel olje og én volumdel n-heptan av spesifisert renhet (se ASTM D1012-51). Egnede metoder til måling av anilinpunktet er beskrevet i ASTM metode D1012-51 og i «IP Standards for Petroleum and its Products» 19. utg., mars 1960 (IP2/56). Metoden for bestem- melse av det blandede anilinpunkt er beskrevet i ASTM metode D1012-51. I prak-sis er det blandede anilinpunkt høyere enn det normale anilinpunkt for de oljer og bestanddeler som er beskrevet i det foreliggende. Sammenlignet med hittil kjente gum-miregenereringsoljer er anilinpunktet for regenereringsoljen ifølge oppfinnelsen meget lavt, særlig da oljen ifølge oppfinnelsen i de fleste tilfelle har et anilinpunkt under 0° C, eksempelvis så lavt som under —38° C. Under anvendelse av de ovenfor beskrevne foretrukne blandinger av alkylbenzener og alkylnaftalener i forholdet 30 : 70 ble den resulterende blanding funnet å ha et anilinpunkt på ca. —38° C. A weight ratio between component A and component B of approx. 20:80 has also been found to be very appropriate. A particularly preferred ratio between component A and component B is therefore between approx. 15:85 and 35:65 by weight. The aniline point for an oil is the lowest temperature for equilibrium dissolution of equal parts by volume of aniline and oil. The mixed aniline point is the lowest temperature for equilibrium dissolution of a mixture of two parts by volume aniline, one part by volume oil and one part by volume n-heptane of specified purity (see ASTM D1012-51). Suitable methods for measuring the aniline point are described in ASTM method D1012-51 and in "IP Standards for Petroleum and its Products" 19th edition, March 1960 (IP2/56). The method of determining measurement of the mixed aniline point is described in ASTM method D1012-51. In practice, the mixed aniline point is higher than the normal aniline point for the oils and ingredients described herein. Compared to previously known rubber regeneration oils, the aniline point of the regeneration oil according to the invention is very low, particularly as the oil according to the invention in most cases has an aniline point below 0° C, for example as low as below -38° C. When using the above-described preferred mixtures of alkylbenzenes and alkylnaphthalenes in the ratio 30:70, the resulting mixture was found to have an aniline point of approx. -38°C.
Oljen ifølge oppfinnelsen kan anvendes for regenerering av syntetisk styren-buta-dien-gummi eller naturgummi eller en blanding av begge gummityper. The oil according to the invention can be used for regeneration of synthetic styrene-butadiene rubber or natural rubber or a mixture of both types of rubber.
I en prosess blir f. eks. gamle dekker etter sortering og fjernelse av metalliske deler sønderrevet i store møller ved riflede valser. Etter sønderrivningen til den ønskede partikkelstørrelse transporteres ma-terialet sammen med regenereringsolje til en oppslutningsbeholder og oppvarmes til ca. 200° C i mellom 3 og 10 timer, hvorunder tekstilmaterialer ødelegges og gum-mien mykgjøres. Vanligvis bruker man i oppslutningsbeholderne tilstrekkelig høye temperaturer til at der kan anvendes et passende svellingsmiddel. In a process, e.g. old tires after sorting and removal of metallic parts shredded in large mills by fluted rollers. After shredding to the desired particle size, the material is transported together with regeneration oil to a digester and heated to approx. 200° C for between 3 and 10 hours, during which textile materials are destroyed and the rubber is softened. Sufficiently high temperatures are usually used in the digestion tanks so that a suitable swelling agent can be used.
Etter at oppslutningen er fullstendig, vaskes oppslutningsbeholderens innhold med vann og tørres i kontinuerlige tørker. Den regenererte gummi blir så blandet under anvendelse av en 84" valse eller en Banbury-blander, hvorunder der om nød-vendig kan tilsettes pigmenter eller ytter-ligere mykgj øringsmidler. Deretter utføres raffineringsprosessen, idet det mykgj orte materiale føres gjennom valser med ruller som roterer med ulik hastighet, og det raf-finerte materiale erholdes i form av en tynn bane. Dette materiale blir så ekstru-dert gjennom fine filterhull, og den således erholdte gummi behandles tilslutt i raffi-neringsvalser. Det tynne baneformede materiale som derved erholdes, kan opprulles på tromler for lagring eller transport. After digestion is complete, the contents of the digester are washed with water and dried in continuous dryers. The regenerated rubber is then mixed using an 84" roller or a Banbury mixer, during which pigments or additional plasticizers may be added if necessary. The refining process is then carried out, the softened material being passed through rollers with rollers which rotates at different speeds, and the refined material is obtained in the form of a thin web. This material is then extruded through fine filter holes, and the rubber thus obtained is finally processed in refining rollers. The thin web-shaped material that is thereby obtained, can be rolled up on drums for storage or transport.
