Definitions
- the invention relates to eco-sustainable production processes of gasolines or a gasoline blend used as vehicle fuel including the use of a non-polluting additive, which does not damage anti- emission systems of modern vehicles, and so obtained gasolines.
- old premium grade gasolines were generally additioned with a lead- (tetraethyl lead) based organometallic compound, in order to reach an Octane Number (ON) of 84 - 97, with respect to the octane requirement of the fleet of circulating motor vehicles.
- a lead- (tetraethyl lead) based organometallic compound in order to reach an Octane Number (ON) of 84 - 97, with respect to the octane requirement of the fleet of circulating motor vehicles.
- anilines were then described in conjunction with what at the time was the principal additive for ON boosting, i.e., tetraethyl lead. Subsequently, metallo- organic compounds (lead, but in some countries also manganese) completely superseded the use of anilines, as the former are much more effective.
- Octane Number is one of the most important parameters of gasoline, as it is directly correlated with power and fuel consumption of the engines in which gasoline is used.
- high octane number gasolines allow to design engines with higher performances, generally by increases in the compression ratio.
- the octane value of gasolines was improved by resorting to organometallic additives, in the near totality of cases lead-based.
- other oxygenated compounds bioethanol
- VOCs volatile organic substances
- prescriptions concern, in particular, gasolines distributed in the summer season and in warmer areas.
- Scope of the present invention is to provide a solution to the above-indicated problems; in particular, it lies in setting up a process having a low environmental impact for the production of high-quality, low-polluting gasolines.
- the present invention is based on the finding that aromatic amines, utilized in the past as mere adjuvants of the action of principal additives for increasing
- the Octane Number such as the organometallic compounds or the aromatic/oxygenated compounds
- object of a first embodiment of the invention is a production process of a gasoline or a blend of unleaded-type high octane number (ON) gasolines, i.e. with a RON greater than 95, wherein the maximum content of total aromatic compounds is 35% (v/v) , the maximum content (v/v) of oxygenated compounds is: methanol 3%, ethanol 5%, isopropanol 10%, t-butanol 10%, ethers having 5 or more Carbon atoms 15%, other oxygenated compounds 10%, and having low volatility, wherein: the process is operated under low-severity conditions, such as to result in a product having a low octane value (ON) , such product is requalified by addition of an aromatic amine-based additive, in an amount comprised between 0.1 % and 3 % (v/v), until obtaining the preset Octane Number.
- maximum content of benzene is 1%, and volatility, better expressed as maximum Vapor pressure
- Ri and R 2 can independently be a hydrogen atom or a methyl, ethyl, n-propyl, iso-propyl, n-butyl, t-butyl, nitrous, phenyl, phenyl-substituted group,
- R3 and R4 can independently be a hydrogen, fluorine, chlorine atom, a methyl, ethyl, n-propyl, iso-propyl, n- butyl, iso-butyl, ter-butyl, amino, amino (C1-C5) -alkyl- substituted, amino-aryl-substituted group, n may be 0, 1 or 2, with the proviso that R3 is not hydrogen when n is 0.
- Object of a third embodiment is a process wherein the product having a low Octane Number, e.g. ranging from 80 to 95 (RON) or from 75 to 88 MON, is a blend into which low-octane number fractions have been integrated.
- a low Octane Number e.g. ranging from 80 to 95 (RON) or from 75 to 88 MON
- the product is a blend whose components are selected from:
- Object of a further embodiment is a process wherein the low-Octane value product is a straight-run gasoline (sometimes denominated "virgin naphtha” or “light naphtha”) or a natural gasoline (sometimes denominated "condensate”) , derived from hydrocarbons, liquid at ambient temperature, present in petroleum gas.
- Objects of other embodiments are:
- low volatility i.e., low Vapor pressure - Vapour Pressure - VP
- Ri and R 2 can independently be a hydrogen atom or a methyl, ethyl, n-propyl, iso-propyl, n-butyl, t-butyl, nitrous, phenyl, phenyl-substituted group,
- R3 and R4 can independently be a hydrogen, fluorine, chlorine atom, a methyl, ethyl, n-propyl, iso-propyl, n- butyl, iso-butyl, ter-butyl, amino, amino (C1-C5) -alkyl substituted, amino-aryl-substituted group, n may be 0, 1 or 2, with the proviso that R3 is not hydrogen when n is 0.
- a gasoline, or gasoline blend, wherein the gasoline supplemented with one or more aromatic amines is a low octane value-type gasoline, like straight-run gasolines
- condensate i.e. derived from hydrocarbons, liquid at ambient temperature, present in petroleum gas, extracted directly at the well mouth.
- object of a further embodiment is the use of a compound containing aromatic amines according to the invention for the requalification of hydrocarbon-based extraction products dispersed in oil field gas, called "condensates”.
- the solution offered by the present invention is to operate plants and production processes under lower severity conditions (exhausted catalysts, lower temperatures, etc) , though producing lower-grade (lower Octane Number) products and requalify the product thus obtained by inclusion of additives that increase its grade, but being not polluting and not falling within the category of the organometallic compounds used in the past to increase the RON and to date totally forbidden.
- the invention offers the possibility of reducing specific energy consumptions maintaining a high grade in the produced gasoline, of preserving plants from excessive stress or wear, by allowing them to produce lower-grade cuts, then raising the grade of the end product by additive use.
- These processes in particular allow production of high-RON gasoline, reducing aromatic and oxygenated compounds content and end product volatility, complying with the prescriptions defined by the above-reported standards.
- These processes provide the use of non-polluting and low-concentration (0.1% to 3%) additives, allowing to increase the ON of the novel reformulated gasolines, ON measured both with the "research” method (RON), i.e. ASTM D 2701 or ISO 5164, and with the "motor” method (MON), i.e.
- a further application of the present invention is that of making available a blend of end gasoline wherein lower-grade cuts may be introduced, without decreasing end fuel performances therefor.
- gasolines or gasoline blends obtained through the process of the invention are products that comply with the provisions of Standard EN 228, prescribing gasoline features in the European Community, but used as guidance also in several other Extra-European countries.
- these gasolines are characterised by: a maximum aromatic compound content of 35%, a maximum benzene content of 1%, and maximum contents of oxygenated compounds as defined hereinafter: methanol (max 3%, with mandatory use of cosolvents/stabilizers) , ethanol (max 5%), iso-propyl alcohol (max 10%), ter-butyl alcohol (max 10%), ethers with 5 or more carbon atoms (max 15%), other oxygenated compounds (max 10%); moreover, a further limitation is prescribed for the oxygenated compounds in terms of maximum oxygen content allowed, i.e. 2.7%, and a maximum vapor pressure equal to about 1 Bar. This is defined as the partial pressure of gasoline vapors at a set temperature, when equilibrium between liquid phase and gaseous phase is achieved, and measured according to method EN 13016-1) .
- These gasolines comprise an aromatic amine-based compound in an amount comprised between 0.1 % and 3 % (v/v) , or between 0.5% and 2%, as additive capable of increasing the ON of low-octane gasolines.
- the gasolines according to the invention are gasolines reformulated soon after elimination of organometallic additives, both lead-based and other metal-based ones (so-called unleaded gasoline).
- Addition of the aromatic ammines of the invention to reformulated gasolines yields a high-ON fuel with a RON value greater than 95, e.g. 96, 97, 98, 99, 100, 101, 102, 103, 104 or 105, the so-called Super Plus gasoline, and gasolines having a high degree of stability and of deterging power, i.e., capable of opposing a fouling tendency in the feeding system.
- the additive of the invention consists in an aromatic amine having the formula:
- Ri and R 2 can independently be a hydrogen atom or a methyl, ethyl, n-propyl, iso-propyl, n-butyl, t-butyl, nitrous, phenyl, phenyl-substituted group
- R3 and R4 can independently be a hydrogen, fluorine, chlorine atom, a methyl, ethyl, n-propyl, iso-propyl, n- butyl, isobutyl, ter-butyl, amino, amino (C1-C5) -alkyl- substituted, amino-aryl-substituted group
- n may be 0, 1 or 2, with the proviso that R3 is not hydrogen when n is 0,
- aromatic amines useful in the present invention are:
- 2-fluoroaniline 2-chloroaniline, N-methylaniline; ortho-toluidine; ortho-ethylaniline; N-methyl-ortho- toluidine; 2, 4-dimethylaniline; 2, 3-dimethylaniline; 2,5- dimethylaniline; 2, 6-dimethylaniline; N-methyl-2, 4- dimethylaniline; N-nitrosodiphenylamine; N-methyl-2, 3- dimethylaniline; N-methyl-2, 6-dimethylaniline, N-ethyl- aniline, N-phenyl-aniline, N-propyl-aniline, N-isopropyl- aniline, N-isobutyl-aniline, N-ter-butyl-aniline, N- isoamyl-aniline, 2-methyl-3-fluoroaniline, 2-fluoro-3- methylaniline, 2-methyl-4-fluoroaniline, 2-fluoro-4- methylaniline, 2, 5-dimethyl-3-fluoroaniline, 2,5
- the aromatic amine compositions can contain other additives suitable for improving specific properties, like e.g. antioxidants, metal deactivators, corrosion inhibitors, deposit modifiers and detergents.
- the abovementioned amine compounds allow to obtain an improvement of the ON in any type of gasoline, both in terms of RON, i.e. the ON measured with the "research” method (ASTM D 2699 or ISO 5164) and in terms of MON, i.e. the ON measured with the "motor” method (ASTM D 2700 or ISO 5163) .
- the mechanism underlying the antiknock function of the molecules subject-matter of the present invention is deemed to be as follows: high-energy free radicals attack the substances subject-matter of the invention, with formation of neutral molecules and new free radicals, whose relative stability allows to control the extent of chain reaction propagation and, therefore, allows the molecules at issue to exert their antiknock effect .
- the present invention can be applied to the following gasoline compositions:
- Oxidation stability (EN ISO 7536) : 360 - 580 min Existent gum content (EN ISO 6246) : 1- 5 mg/kg Aromatic hydrocarbon content: 5 - 35 % (v/v) Olefinic hydrocarbon content: 0 - 18 % (v/v) Benzene content: 0.1 - 1 % (v/v)
- gasolines are produced by suitably mixing components obtained in refineries, with respect to their plant configuration. Principal components used are the following:
- Butane gases (mainly containing hydrocarbons having 4 C atoms) ;
- Reformed gasoline (with a different degree of severity in connection with features the end gasoline shall have) ;
- Gasoline from alkylation process Light gasoline from cracking process
- Oxygenated compounds introduced or produced in the same refinery generally MTBE.
- ON boosters apart from ON boosters, they can contain additives suitable for improving specific properties, like, e.g., antioxidants, metal deactivators, corrosion inhibitors, deposit modifiers and detergents.
- aromatics content can conveniently be controlled by reducing the severity of the reforming process (which transforms linear-chain paraffinic hydrocarbons into cyclic, mainly aromatic hydrocarbons through a dehydrogenation mechanism) .
- Olefinic hydrocarbon content can instead be controlled by reducing the amounts of gasoline from cracking used.
- the gasoline according to the invention is a gasoline having a low octane value, such as straight-run gasolines (sometimes denominated “virgin naphtha” or “light naphtha”) or a natural gasoline (sometimes denominated “condensate”), i.e., derived from hydrocarbons, liquid at ambient temperature, present in petroleum gas, extracted directly at the mouth of the oil well.
- a gasoline having a low octane value such as straight-run gasolines (sometimes denominated “virgin naphtha” or “light naphtha") or a natural gasoline (sometimes denominated “condensate”), i.e., derived from hydrocarbons, liquid at ambient temperature, present in petroleum gas, extracted directly at the mouth of the oil well.
- These products mainly contain saturated linear- chain hydrocarbons, and therefore are characterized by relatively low octane values.
- the present invention also relates to the use of a compound including aromatic amines in the management of virgin naphtha refineries: in fact, a naphtha cut usually exhibits a low RON and therefore is normally intended to be reprocessed in other plants, such as Catalytic Reforming and Isomerization ones.
- the present invention also relates to the use of a compound including aromatic amines for an oil field extraction product, i.e. the "condensates” that define gas-dispersed hydrocarbons and therefore are entrained by the flow of an extraction well, and subsequently isolated into suitable separators; they may be light hydrocarbons or even rather heavy ones, usually paraffinic hydrocarbons .
- "condensates" from gas extraction fields have features very similar to those of gasolines, constituting a possible component of the blend of end gasolines. In general, however, those are components which lower the RON of the end product, or that anyhow do not give a RON meeting market-required values.
- Another advantage of the aromatic amine-based compound is that of allowing introduction into the end gasoline of cuts from Fluid Catalytic Cracking and Thermal Cracking (refining and petrochemical), which usually have a high RON (not accepted by car makers) but a much worse MON.
- the compound subject-matter of the patent allows to raise the MON of these cuts, which therefore can be used directly, without undergoing further processing; this entails once again a remarkable reduction of specific energy consumptions.
- any correction to the Octane Number by resorting to the present invention allows not to incur such problems.
- the addition of a small amount of additive does not require availability of further mixability, nor does it modify other end gasoline features. At the same time, it significantly reduces the technical times for effecting the correction and allows work and energy saving.
- a series of aromatic amines subject-matter of the present invention were evaluated in state-of-the-art unleaded gasolines (intended to be used in motor drives managed by Euro III, Euro IV and Euro V electronic system), always using the same test pattern.
- N-Nitrosodiphenylamine 2.5 N, N-Dimethyl-p-phenylendiamine : 1.8 N, N-Diethyl-p-phenylendiamine : 1.8 N-methylaniline : 0.8 2, 6-dimethylaniline: 0.7 3, 5-dimethylaniline: 0.7 2, 3-dimethylaniline : 0.6 2, 5-dimethylaniline: 0.5
- Example 2 Testing was conducted on various gasolines having typical features of products to which the present invention applies. Therefore, each of these formulations was supplemented with different dosages of 2,4- dimethylaniline containing an aromatic amine, and each of the samples thus obtained was analyzed in a laboratory by performing RON and MON measuring, with methods ISO 5164
- Aromatic amines used in the present example are selected from:
- Oxidation stability (EN ISO 7536) : 360 - 580 min Existent gum content (EN ISO 6246) : 1- 5 mg/kg Aromatic hydrocarbon content: 5 - 35 % (v/v) Olefinic hydrocarbon content: 0 - 18 % (v/v) Benzene content: 0.1 - 1 % (v/v)
- Main components used in this gasoline are the following ones:
- Butane gases (mainly containing hydrocarbons having 4 C atoms) ;
- Reformed gasoline (with a different degree of severity in connection with features the end gasoline shall have) ; Gasoline from alkylation process;
- Oxygenated compounds introduced or produced in the same refinery generally MTBE.
- the example relates to gasolines having a low octane value, such as straight-run gasolines (sometimes denominated “virgin naphtha” or “light naphtha”) or natural gasolines (sometimes denominated “condensates”), i.e., hydrocarbons, liquid at ambient temperature, present in petroleum gas, extracted directly at the mouth of the oil well.
- the products mainly contain saturated linear-chain hydrocarbons and therefore are characterized by relatively low octane values, having base product RON and MON ranging respectively between 85 and 90 (RON) and 75 and 80 (MON) .
- These gasolines were supplemented with different dosages of 2, 4-dimethylaniline .
- Results in terms of dosage in % (v/v) by 1-point increase of RON or MON, were: 0.25% (v/v) /RON and 0.40% (v/v) /MON.
- Response curve pattern linear (R2 > 0.9) .
- the use of the aromatic amine can aid the refining in increasing the isomerate number in the gasoline blend.
- a dose of aromatic amine of about 3000 ppm by volume causes a RON increase in the treated blend of 1 RON unit, and a minimum of 0.5 MON units.
- results are reported in terms of dosage corresponding to 1-point increases of RON and MON, as well as linear regression coefficients (R2) of the regression line related to results obtained at the various dosages subjected to tests.
- N-Nitrosodiphenylamine dosage for 1-point increase of RON 0.11 ⁇ ; (v/v) ; dosage for 1-point increase of MON 0.16 % ; (v/v) ; N, N-Dimethyl-p-phenylendiamine: dosage for 1-point increase of RON 0.15 ⁇ i (v/v) ; dosage for 1-point increase of MON 0.18 ⁇ ⁇ (v/v) ; N, N-Diethyl-p-phenylendiamine : dosage for 1-point increase of RON 0.15 ⁇ i (v/v) ; dosage for 1-point increase of MON 0.19 ⁇ ; (v/v) ;
