Gasoline fuel and method of making and using it. The fuel comprises from 5 to 20 vol.-% paraffinic hydrocarbons originating from biological oils, fats, or derivatives or combinations thereof. Further, it comprises oxygenates, such as ethanol present in a concentration of about 5 to 15 vol.-%; or iso-butanol present in a concentration of 5 to 20 vol.-%, preferably about 10 to 17 vol.-%; or ETBE present in a concentration of 7 to 25 vol.-%, preferably about 15 to 22 vol.-%. The bioenergy content of the gasoline is at least 14 Energy equivalent percentage (E-%) calculated based on the heating values given in the European Renewable Energy Directive 2009/28/EC. By means of the invention, fuels with a high bioenergy content are provided which can be used in conventional gasoline-fuelled automotive engines.

In the process of the invention, an aliphatic C-Chydrocarbon product is prepared from natural fats or derivatives thereof. The process comprises the steps of: (i) providing a natural fat or derivative thereof, (ii) deoxygenating a natural fat or derivative thereof originating from step (i) to yield an aliphatic C-Chydrocarbon, (iii) hydrocracking an aliphatic C-Chydrocarbon originating from step (ii) to yield a product comprising an aliphatic C-Chydrocarbon, (iv) isomerising an aliphatic C-Chydrocarbon originating from step (iii) into an isomerised aliphatic C-Chydrocarbon, and optionally (v) recovering an isomerised C-Chydrocarbon originating from step (iv) as said C-Chydrocarbon product. Pure and high quality light fuel is easily obtained in sufficient amounts.
