Abstract

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 eqv -%) 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.

First claim

The invention claimed is:

1. Gasoline fuel comprising paraffinic hydrocarbons originating from biological oils, fats, or derivatives or combinations thereof as a concentration ranging from 5 to 20 vol.-%, and oxygenates as a concentration ranging from 5 to 25 vol.-% calculated from the total volume of the fuel, wherein a bioenergy content of the fuel is at least 14 Energy equivalent percentage (Eeqv-%), said Energy Equivalent percentage being calculated based on the heating values given in the European Renewable Energy Directive 2009/28/EC.

2. Gasoline fuel comprising paraffinic hydrocarbons originating from biological oils, fats, or derivatives or combinations thereof as a concentration ranging from 5 to 20 vol.-%, and oxygenates as a concentration ranging from 5 to 25 vol.-% calculated from the total volume of the fuel,
wherein the paraffinic hydrocarbons originating from biological oils, fats, or derivatives or combinations thereof are derived from an intermediate hydrocarbon product having aliphatic C 9 to C 28 and derived from a natural fat or derivative thereof to yield a hydrocracked product of aliphatic C 2 to C 14 hydrocarbons.

3. The fuel according to claim 2 , wherein the aliphatic C 2 to C 14 hydrocarbons are isomerized and form a hydrocarbon composition comprising isomerised C 2 to C 14 hydrocarbons.

4. Gasoline fuel comprising paraffinic hydrocarbons originating from biological oils, fats, or derivatives or combinations thereof as a concentration ranging from 5 to 20 vol.-%, and oxygenates as a concentration ranging from 5 to 25 vol.-% calculated from the total volume of the fuel,
wherein the paraffinic hydrocarbons originating from biological oils, fats, or derivatives or combinations thereof are a side product of a hydrotreated feedstock of biological oils or fats or combinations thereof which were hydrotreated at a reaction temperature of 200 to 400 degrees C. in the presence of a catalyst.
