Kerosene composition

Abstract

A kerosene composition useful as heating fuels is provided 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 which have from 9 to 18 carbon atoms and/or alkyl derivatives thereof.

We claim:  
     
         1 . A kerosene composition comprising at least 99 wt % of a) at least one n-paraffins and/or iso-paraffins, said n-paraffins and/or iso-paraffins having from 7 to 18 carbon atoms and b) at least one cyclo-paraffins and/or alkyl derivatives thereof having from 9 to 18 carbon atoms.  
     
     
         2 . The kerosene composition of  claim 1  wherein at least 99 wt % of said n-paraffins and/or iso-paraffins have from 7 to 12 carbon atoms.  
     
     
         3 . The kerosene composition of  claim 1  wherein at least 99 wt % of said cyclo-paraffins have from 9 to 12 carbon atoms.  
     
     
         4 . The kerosene composition of  claim 1  wherein the ratio by weight of the n-paraffins and/or iso-paraffins to the cyclo-paraffins and/or alkyl derivatives thereof is from 92:8 to 25:75.  
     
     
         5 . The kerosene composition of  claim 4  wherein said ratio is from 85:15 to 55:45.  
     
     
         6 . The kerosene composition of  claim 1  having a smoke point of at least 30 mm.  
     
     
         7 . The kerosene composition of  claim 1  wherein the component a) is selected from the group consisting of 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, 2,2-dimethylnonane, and mixtures thereof.  
     
     
         8 . The kerosene composition of  claim 1  wherein component b) is selected from the group consisting of n-butyl-cyclopentane, n-pentyl-cyclopentane, n-hexyl-cyclopentane, isopropyl-cyclohexane, n-butyl-cyclohexane, n-pentyl-cyclohexane, n-hexyl-cyclohexane, cis-decahydronaphthalene, trans-decahydronaphthalene, 1-methyl-(trans-decahydronaphthalene), 9-ethyl-(cis-decahydronaphthalene), and mixtures thereof.  
     
     
         9 . The kerosene composition of  claim 8  wherein the component b) is selected from cis- and trans-decahydronaphthalene and mixtures thereof.  
     
     
         10 . The kerosene composition of  claim 1  wherein the n-paraffins and iso-paraffins have been obtained by means of Fischer-Tropsch synthesis.  
     
     
         11 . The kerosene composition of  claim 4  wherein the n-paraffins and iso-paraffins have been obtained by means of Fischer-Tropsch synthesis.  
     
     
         12 . The kerosene composition of  claim 6  wherein the n-paraffins and iso-paraffins have been obtained by means of Fischer-Tropsch synthesis.  
     
     
         13 . The kerosene composition of  claim 4  having a smoke point of at least 30 mm.  
     
     
         14 . The kerosene composition of  claim 5  having a smoke point of at least 30 mm.  
     
     
         13 . The kerosene composition of  claim 7  having a smoke point of at least 30 mm.  
     
     
         14 . The kerosene composition of  claim 8  having a smoke point of at least 30 mm.
