Abstract (en)
Airplane fuel (I) obtained from a synthesis gas having a carbon-content of 84-86 mass%, an olefin-content of less than 0.1 mass%, an alcohol content of less than 0.1 mass%, and an isoparaffin content of greater than 75 mass%, and exhibiting a freezing point of = -47[deg] C, is claimed, where the ratio of isoparaffin to sum of normal paraffin, cycloparaffin and aromate is greater than 3. Independent claims are included for: (1) preparing (I) from 1-5C alcohol, comprising oligomerizing and/or polymerizing a synthetic hydrocarbon with an isoparaffin portion of at least 75 mass% and olefin hydrocarbon mixture with a portion of odd olefin and isoolefin of at least 50 mass%, which is obtained at least partly from 1-5C-alcohol, and hydrogenating and rectifying the obtained mixture, and removing the kerosene; and (2) a use of (I) as a mixture components (comprising normal paraffin (less than 25 mass%) and tetradecane (maximum of 2 mass%), where: the content of normal paraffins with 15C-atoms is less than 0.5 mass%, the total content of normal paraffins with 15-18C-atoms is less than 0.3 mass% and the total content of normal paraffins with 18C-atoms is less than 0.1 mass%) for mixing with conventional fuels.
