Description
451 197 Kvar fanns sålunda uppgiften att utveckla tillsatsämnen för be- fordrande av flytande bränslens förbränning, vilka ämnen inte har de hos kända tillsatsämnen påvisade nackdelarna, dvs framförallt är lättlösliga i olja och ej giftiga och dessutom lätt Och ekono- miskt tillgängliga. 451 197 Thus, the task remained to develop additives for promoting the combustion of liquid fuels, which substances do not have the disadvantages demonstrated in known additives, ie are above all readily soluble in oil and non-toxic and also readily and economically available.
Uppfinningen består i användningen av järn- och/eller mangansalter av alifatiska karboxylsyror med 3 till 10 kolatomer i en koncent- ration av 5 till 100 ppm metall, räknat på det flytande bränslet, som förbränningshjälpmedel för flytande bränslen. Med flytande bränslen avses i samband med föreliggande uppfinning material för värmealstring, som t.ex. brännoljans mittendestillat, t.ex. bränn- olja EL, men också tyngre brännolja eller återstoder, som erhålles vid kemiska processer.The invention consists in the use of iron and / or manganese salts of aliphatic carboxylic acids having 3 to 10 carbon atoms in a concentration of 5 to 100 ppm of metal, based on the liquid fuel, as combustion aids for liquid fuels. Liquid fuels in connection with the present invention refer to materials for heat generation, such as e.g. the middle distillate of the fuel oil, e.g. fuel oil EL, but also heavier fuel oil or residues, which are obtained in chemical processes.
Syrorna, som ligger till grund för de enligt uppfinningen utnytt- jade salterna, kan vara raka eller grenade och isynnerhet K-grena- de. Som exempel på sådana syror kan nämnas smörsyra, isosmörsyra, n-valeriansyra, 2-metylsmörsyra, 3-metylsmörsyra, 2-etylsmörsyra, 2,3~dimetylsmörsyra, 2-metylpentansyra, 2-etylpentansyra, 2-etyl- hexansyra, isooktansyra, isononansyra och isodekansyra.The acids on which the salts used according to the invention are based can be straight or branched and in particular K-branched. Examples of such acids are butyric acid, isobutyric acid, n-valeric acid, 2-methylbutyric acid, 3-methylbutyric acid, 2-ethylbutyric acid, 2,3-dimethylbutyric acid, 2-methylpentanoic acid, 2-ethylpentanoic acid, 2-ethylhexanoic acid, isooctanoic acid, isooctanoic acid and isodecanoic acid.
Metallerna föreligger i salterna i form av järn(III)- resp. man- gan(II)-jon.The metals are present in the salts in the form of iron (III) - resp. man- gan (II) -jon.
Framställning av salterna kan på känt sätt ske genom omsättning'" av ett i vatten löst metallsalt, t.ex. järnnitrat eller mangannit- rat med en karboxylsyra med den preciserade molekylstorleken i när- varo av alkalihydroxid. Tillsats av karboxylsyror och alkalihydr- oxid kan ske samtidigt (enstegsmetod) eller i följd efter varandra (tvâstegsmetod).The salts can be prepared in a known manner by reacting a metal salt dissolved in water, for example iron nitrate or manganese nitrate with a carboxylic acid of the specified molecular size in the presence of alkali hydroxide. Addition of carboxylic acids and alkali metal hydroxide can take place simultaneously (single-step method) or sequentially (two-step method).
Salterna kan sättas till det flytande bränslet för sig ensamma, gemensamt, tillsammans med andra tillsatsämnen i fast eller löst form. De utvecklar sin verkan redan vid koncentrationer av några få ppm, och enligt föreliggande uppfinning använder man dem i kon- centrationer av 5 till 100 ppm metall, räknat på det flytäflfie bränslet.The salts can be added to the liquid fuel alone, together, together with other additives in solid or loose form. They develop their action already at concentrations of a few ppm, and according to the present invention they are used in concentrations of 5 to 100 ppm of metal, based on the liquid fuel.
Enligt uppfinningen användes sålunda 5 till 100 ppm, isynnerhet 5 __ i» _.. ,_-.-_ __.__i-_.._........ r____._-.. u” 451 1097 till 25 ppm, metall i form av det lösta saltet som tillsatsämne, vilket främjar förbränningen. Lämpligen blandar man in tillsats- ämnet, eventuellt tillsammans med andra tillsatsämnen, i det fly- tande bränslet i form av koncentrat. För framställningen av koncent- ratet lämpar sig isynnerhet en mineraloljefraktion (spindelolja) med 15 till 25 cSt/20pC. För upplösningen av tillsatsämnena är emellertid även lösningsmedel på basis av aromatiska kolväten med en flampunkt av över 55°C användbara.According to the invention, 5 to 100 ppm are thus used, in particular 5 __ i »_ .., _-.-_ __.__ i -_.._........ r ____._- .. u” 451 1097 to 25 ppm, metal in the form of the dissolved salt as an additive, which promotes combustion. It is convenient to mix the additive, possibly together with other additives, into the liquid fuel in the form of concentrate. A mineral oil fraction (spindle oil) of 15 to 25 cSt / 20pC is particularly suitable for the preparation of the concentrate. However, for the dissolution of the additives, solvents based on aromatic hydrocarbons with a flash point above 55 ° C are also useful.
Följande exempel är ägnade att åskådliggöra uppfinningen utan att begränsa dess omfattning.The following examples are intended to illustrate the invention without limiting its scope.
Den i exemplen utnyttjade brännoljan EL kan försättas med sådana tillsatsämnen som medel, vilka förbättrar fririnningsförmågan, an- tioxidanter, metalldesaktivatorer, dispergermedel och korrosions- inhibitorer.The fuel oil EL used in the examples can be added with such additives as agents which improve the free-flowing ability, antioxidants, metal deactivators, dispersants and corrosion inhibitors.

Rökgastemperaturen uppvi- sade ett värde av 242°C, medan luftdraget hade ett värde av 0,2 mbar.Example 1 In a test boiler according to DIN 4702 with an output of 81 kW, fuel oil EL, which contains an addition of iron (III) -2-ethylhexanoate, dissolved in spindle oil (1 part spindle oil / additive of 4000 parts fuel oil EL), is fired. calculated at approx. 10 ppm iron, calculated on fuel oil, ugpxx kontroll er controlled technical conditions according to DIN 4702, the CO2 content in the flue gas amounted to 12.1%. The flue gas temperature showed a value of 242 ° C, while the draft had a value of 0.2 mbar.
Sctsiffervärdet i rökgasen enligt Bacharach i enlighet med DIN 51 402 sjönk med tillsatsämnet i brännoljan EL i förhållande till sctsiffervärdet i rökgasen utan tillsatsämne i brännolja EL från 4,50 skalpunkter till 2,50 skalpunkter. Minskningen i sotbildningen uppgick till 44%.The sci value in the flue gas according to Bacharach in accordance with DIN 51 402 decreased with the additive in the fuel oil EL in relation to the sci value in the flue gas without additive in fuel oil EL from 4.50 scale points to 2.50 scale points. The reduction in soot formation amounted to 44%.

Sotbildningens minskning utgjorde 58,5%.Example 2 The experiment was carried out as described in Example 1 with the difference that the fuel oil EL contained 15 ppm of iron in the form of ferric (III) -2-ethylhexanoate. The spindle oil also contained anti-corrosion additives. The soot value of the flue gas decreased with the additive from 5.00 scale points to 3.00 scale points.
