Uppfinnare: A Champagnat Prioritet begiird few den 22 augnsti 1960 (Frankrike) Denna uppfinning hanfor sig till petroleumbrannolj eblandningar, vilka innehalla en vdsentlig mangd restbrannolja. Denna typ av brannolja kan framstallas ur en rest erhallen Iran en vaxartad raolja och det fir vanligen nadvandigt att utspada resten med en gasolja for erhallande av en brannolja, vars viskositet är installd enligt fOreskrifterna. Sadana brannoljor kunna innehalla bade vaxartade material och asfaltener och deras hallningspunkter aro ofta aIltf8r hoga for att medgiva fOrvaring och for att de latt skola kunna pumpas vid laga temperaturer. Vissa liknande brannolj or framstailda ur nafteniska raoljor uppvisa icke denna nackdel. Inventor: A Champagne Priority Begiird Few August 22, 1960 (France) This invention relates to petroleum fuel oil compositions which contain a substantial amount of residual fuel oil. This type of fuel oil can be produced from a residue obtained in Iran a waxy crude oil and it is usually necessary to dilute the residue with a gas oil to obtain a fuel oil, the viscosity of which is adjusted according to the regulations. Such fuel oils may contain both waxy materials and asphaltenes and their slope points are often too high to allow storage and to be easily pumped at low temperatures. Some similar fuel oils prepared from naphthenic crude oils do not have this disadvantage.

Manga tillsatser aro kanda, vilka firo effektiva for reducering av hallningspunkten hos smorjoljor och vaxartade gasoljor, men dessa tillsatser ha icke nagon namnvfird inverkan pa hallningspunkten hos restbrannoljor, sannolikt emedan de senare innehalla asfaltener, vilka icke forekomma i smorjoljor och gasoljor. Restbranslen aro mycket billigare an smorjoljor och det ãr icke onskvart att Oka kostnaderna, exempelvis genom anvandning av en dyrbar tillsats eller en tillsats, vilken är dyrbar vid arbetskoncentrationen. Denna uppfinning avser brannoljeblandningar innehallande en tillsats, vilken icke fir forbunden mcd de ovannamnda nackdelarna. Many additives are known to be effective in reducing the pour point of lubricating oils and waxy gas oils, but these additives have no significant effect on the pour point of residual fuel oils, probably because the latter contain asphaltenes which do not occur in lubricating oils and gas oils. Residual fuels are much cheaper than lubricating oils and it is not unreasonable to increase costs, for example by using an expensive additive or an additive which is expensive at the concentration of work. This invention relates to fuel oil mixtures containing an additive which is not associated with the above-mentioned disadvantages.

Enligt uppfinningen bestar en brannoljeblandning i huvudsak av en liten mangd av en tillsats lost i en grundolja, vilken tillsats bestar av en eller flora av de diestrar, som bildas mellan tvh moldelar av en glykol eller polyglykol innehallande 2-10 kolatomer per molekyl och en moldel av en blandning av: en klorerad fettsyra och en mattad fettsyra med minst 10 och fOretradesvis minst 18 kolatomer per molekyl eller en blandning av sadana syror eller en sadan blandning innehallande en liten mangd omfittade och/eller ofOrtvalbara syror, varvid molforhallandet 1) : 2) är 1: 0,5-2 och foretradesvis ekvimolart och grundolj an ar en petroleumbrannolja, vilken innehaller alminstone en vasentlig mfingd av en destillationsrest. Foretradesvis Si den klorerade fettsyran en sadan med formeln C1C,11-12COOH, i vilken n betecknar ett helt tal Over 0 och under 11, isynnerhet monoklorattiksyra. De foredragna tillsatserna aro sadana, som framstallas av monoetylenglykol, dietylenglykol, trietylenglykol och propylenglykol exempelvis den diester som bildas mellan en. moldel dietylenglykol och tvh moldelar av en ekvitnolar blandning av monoklorattiksyra och. ullfettstearin, Foretradesvis innehaller brannolj eblandningen enligt uppfinningen 0,01-1 vikt-%, exempelvis omkring 0,1-0,3 vikt-% av tillsats en. According to the invention, a fuel oil mixture consists essentially of a small amount of an additive lost in a base oil, which additive consists of one or more flora of the diesters formed between two moieties of a glycol or polyglycol containing 2-10 carbon atoms per molecule and a moiety. of a mixture of: a chlorinated fatty acid and a saturated fatty acid having at least 10 and preferably at least 18 carbon atoms per molecule or a mixture of such acids or such a mixture containing a small amount of fatty and / or non-selectable acids, the molar ratio 1): 2) is 1: 0.5-2 and preferably equimolar and base oil is a petroleum fuel oil which contains at least one essential part of a distillation residue. Preferably the chlorinated fatty acid is one of the formula C1C, 11-12COOH, in which n represents an integer above 0 and below 11, in particular monochloroacetic acid. The preferred additives are those prepared from monoethylene glycol, diethylene glycol, triethylene glycol and propylene glycol, for example the diester formed between one. mold part diethylene glycol and two mold parts of an equinolar mixture of monochloroacetic acid and. wool grease stearin. Preferably, the fuel oil mixture according to the invention contains 0.01-1% by weight, for example about 0.1-0.3% by weight of additive one.

Restpetroleumbrfinnolj or innehalla vanligen omkring 20-80 vikt-% av destillationsresten, vilken kan vara antingen en vakuumrest eller en atmosfarisk rest, och blandningar av hada typerna av rest anvandas ibland. Man kan aven inforliva de fiesta petroleumkolvatematerial, exempelvis rester frail kracknings- och kemiska omvandlingsprocesser, forutsatt att den fardiga blandningen har en viskositet och en flampunkt enligt specifikationerna. Ofta innehaller "blandningen endast destillationsrester och gasolj a, varvid den ex akta blandningen beror ph rholjan, behandlingsbetingelserna, etc., och vanliga blandningar aro a) omkring 50 vikt-% vakuumrest och ()Inkling 50 vikt-% gasolja och b) omkring 70 vikt-% atmosfarisk rest ocb. omkring 2—1868 =- vikt-% gasolja. Alla dessa restbrannoroljor ge tillfredsst5.11ande hallningspunkter nar de anvandas som grundolja i blandningar enligt uppfhuiingen. Residual petroleum oils usually contain about 20-80% by weight of the distillation residue, which may be either a vacuum residue or an atmospheric residue, and mixtures of the different types of residue are sometimes used. It is also possible to incorporate most petroleum carbonate materials, for example residues from cracking and chemical conversion processes, provided that the finished mixture has a viscosity and a flash point according to the specifications. Often the mixture contains only distillation residues and gas oil, the exact mixture depending on the oil, the treatment conditions, etc., and common mixtures are a) about 50% by weight of vacuum residue and () Inclusion 50% by weight of gas oil and b) about 70 % by weight of atmospheric residue and about 2-1868 = -% by weight of gas oil All of these residual fuel oils provide satisfactory pour points when used as base oil in mixtures according to the invention.
