Definitions
- the present invention relates to kerosene compositions, particularly for use as heating fuels, which have excellent performance in that, for example, they do not have an unpleasant odour when they are being handled, when they are being ignited or when they are being extinguished, the combustion exhaust gas is clean and the storage stability is high.
- Kerosene is widely used for heating and for cooking purposes.
- Conventional kerosene when used for heating purposes, has an oily smell when the kerosene is being handled on refuelling and this is unpleasant for the user.
- open-type stoves such as portable stoves and fan heaters, for example, or when used in a small kitchen oil range for cooking purposes, for example, on lighting and on extinguishing, the combustion is incomplete and there is a disadvantage in that an unpleasant smell is produced by the unburned hydrocarbons which are produced at this time.
- kerosenes comprising iso-paraffins and n-paraffins which have 9 or 10 carbon atoms as the main components have a lower density than existing kerosenes and the fuel consumption by volume is increased, and so, for example, it is likely that the JIS specification (of the Japanese Standards Association) for fuel consumption in an oil stove will not be satisfied. Moreover, the flash point is reduced and there are also problems with safety.
- the present invention is intended to provide kerosene compositions for which the cost, fuel consumption and flash point are similar to those of kerosenes in general, and with which, unlike those obtained using conventional methods, the smell of the kerosene itself is very slight, there is no unpleasant oily smell when it is being handled, with which there is no smell on ignition and extinguishing, which has good combustibility, with which the exhaust gas on combustion is clean, and which also has excellent storage stability.
- a kerosene composition containing at least 99 wt% of n-paraffins which have from 7 to 18 carbon atoms and/or iso-paraffins which have from 7 to 18 carbon atoms along with cyclo-paraffins, and alkyl derivatives thereof, which have from 9 to 18 carbon atoms.
- at least 99 wt% of said n-paraffins and/or iso-paraffins have from 7 to 12 carbon atoms.
- at least 99 wt% of said cyclo-paraffins have from 9 to 12 carbon atoms .
- the ratio by weight of the n-paraffins and/or iso-paraffins to the cyclo-paraffins and alkyl derivatives thereof is preferably from 92:8 to 25:75, more preferably from 85:15 to 55:45.
- Said kerosene composition according to the present invention preferably has a smoke point of at least 30 mm.
- the n-paraffins and iso-paraffins which have from 7 to 18 carbon atoms which are used in the present invention can be obtained by taking synthetic gas obtained by partial oxidation, steam reforming from coal, natural gas, for example, and producing long-chain alkyl hydrocarbon polymer oil by means of a
- Fischer-Tropsch reaction and then carrying out hydrocracking and distillation. Furthermore, they can also be obtained in view of production costs by cracking or synthesis, for example, from the various fractions which are obtained in petroleum refining.
- n-paraffins or iso-paraffins have less than 7 carbon atoms then the boiling point and flash point are too low and this is undesirable, and if the number of carbon atoms exceeds 18 then there are problems with low temperature fluidity, the boiling point is also raised too far and there is an adverse effect on the combustibility, which is undesirable.
- n-paraffins and iso-paraffins which can be used in the present invention include n-heptane, iso-heptane, n-octane, iso-octane, n-nonane, iso-nonane, n-decane, iso-decane, n-undecane, iso-undecane, n-dodecane, iso-dodecane, 2-methylheptane, 2, 2-dimethylhexane, 2-methyloctane, 2, 2-dimethylheptane, 2-methylnonane, 2, 2-dimethyloctane, 2-methyldecane and 2-dimethylnonane.
- the cyclo-paraffins, and the alkyl derivatives thereof, which have from 9 to 18 carbon atoms and which can be used in the present invention can be obtained by the hydrogenation of the light oil and intermediate oil fractions obtained by the distillation of coal tar, or by separation by distillation from crude oil and hydrogenation of the various distillate fractions.
- the number of carbon atoms of the cyclo-paraffins or alkyl derivatives thereof is less than 9 then the flash point is too low and this is undesirable, and if the number of carbon atoms exceeds 18 then the boiling point is too high and there is an adverse effect on the combustibility, and this is undesirable.
- cyclo-paraffins and alkyl derivatives thereof which can be used in the present invention include n-butyl-cyclopentane, n-pentyl-cyclopentane, n-hexyl-cyclopentane, isopropyl-cyclohexane, n-butylcyclohexane, n-pentyl-cyclohexane, n-hexyl-cyclohexane, cis-decahydronaphthalene, trans-decahydronaphthalene, 1-methyl- (trans-decahydronaphthalene) and 9-ethyl- (cis-decahydronaphthalene) .
- the kerosenes of the present invention must contain at least 99 wt% of the aforementioned n-paraffins and/or iso-paraffins along with the cyclo-paraffins and alkyl derivatives thereof. If the content is less than 99 wt%, then aromatic components, olefinic components, oxygen-containing components, nitrogen-containing components and sulphur-containing components are admixed and a smell is observed when handling, igniting and extinguishing the kerosene, and the storage stability is of the same order as that of a general kerosene.
- the mixing ratio by weight of the n-paraffins and/or iso-paraffins to the cyclo-paraffins and alkyl derivatives thereof is preferably from 92:8 to 25:75, and most preferably from 85:15 to 55:45. If the cyclo-paraffins and alkyl derivatives content thereof is high then the smoke point which indicates the combustibility is less than 30 mm and so this is undesirable, and if it is low then the flash point falls below the JIS specification and actual fuel consumptions (L/h) become greater than the indicated fuel consumptions by volume for the stoves and exceed the +10% of the JIS specification and so this is undesirable.
- said n-paraffins and/or iso-paraffins have been obtained by means of Fischer-Tropsch synthesis.
- the kerosene compositions of the present invention comprising the compositions indicated above have the properties (1) to (4) indicated below, and in particular they have a high smoke point and excellent combustibility. As the smoke point is raised and the combustibility is improved, the time from ignition to complete combustion is shortened and complete combustion is promoted in the steady combustion state.
- Distillation IBP Initial Boiling Point
- the 95% distillation temperature is less than 270°C.
- Smoke point is at least 30 mm (compositions with smoke points of at least 35 mm, and even of 40 mm can also be obtained.)
- Figure 1 shows the change in the Saybolt value in an oxidation stability test
- Figure 2 shows the change in the amount of peroxide in an oxidation stability test.
- n-paraffin/iso-paraffin mixed oil of the composition shown in Table 1 was obtained by production with the SMDS (Shell Middle Distillate Synthesis) process, in which natural gas is partially oxidised, heavy paraffins are synthesised by means of Fischer-Tropsch synthesis, and naphtha, kerosene and light oil fractions are obtained by hydrocracking of the heavy paraffin oil obtained, and distillation.
- SMDS Shell Middle Distillate Synthesis
- concentrations of the iso-paraffins in Table 1 indicate the concentrations of all of the branched hydrocarbons which have the same carbon number since it is difficult to determine the isomers with different structures.
- iso-octane includes all isomers such as 2-methylheptane, 2, 2-dimethylhexane and the like.
- Example 3 Twenty five parts by weight of the n-paraffin/iso-paraffin mixed oil obtained in Example 1 and 75 parts by weight of decalin were mixed and an n-paraffin/iso-paraffin/decalin mixed kerosene was obtained.
- the properties of the kerosene compositions of the present invention showed a smoke point much higher than that of Comparative Example 2, superior burning properties and a smaller sulphur fraction. Furthermore, they had a higher ignition point (flash point) than that of Comparative Example 1, and the JIS specification was satisfied.
- Combustion performance tests were carried out using a .wick top to bottom type stove and a petroleum fan heater.
- the fuel consumption for maximum burning and the CO/CO2 ratio of the exhaust gas were measured in accordance with the test methods laid down in JIS S 2019 and JIS S 2031 in the case of the wick top to bottom type stove and in accordance with JIS S 2036 and JIS S 3031 in the case of the petroleum fan heater.
- the results obtained are shown in Table 3.
- the kerosene compositions of the present invention had a lower CO/CO2 and a much lower SO2 content in the exhaust gas when compared with the kerosene of Comparative Example 2, and they provided a cleaner exhaust gas. Furthermore, the kerosene of Comparative Example 1 was such that the difference between the indicated and measured fuel consumption (L/h) per stove capacity did not satisfy the JIS specification of within ⁇ 10%, while the kerosene compositions of the present invention did satisfy this JIS specification. Odour Function Test
- the kerosene compositions of the present invention were such that the kerosenes themselves had less odour than the kerosene of Comparative Example 2, and they also had less odour when they were lit and when they were extinguished.
- kerosene composition for which the cost, fuel consumption and ignition point are the same as those of a general kerosene, with which the odour of the kerosene itself is very slight so that there is no unpleasant oily smell when it is being handled, which has good burning properties and provides a clean exhaust gas when it is burned, and which has excellent storage properties, which has not been obtained with conventional methods.
