Fuel blend comprising a mixture of aryl ethers

Fuel blend comprising:

• as a major portion, a first internal combustion engine fuel being a mixture of paraffinic diesel and fossil diesel;
• and
• as a minor portion, a fuel component, a second internal combustion engine fuel, wherein the internal combustion engine fuel is diesel, and wherein the fuel component includes a mixture of five or more aryl ethers, the mixture containing less than 1 wt % of compounds having a free alcohol group, and wherein the minor portion of the fuel component comprising aryl ethers accounts for 50 wt % or less of the total fuel blend, but more than 10% of the total fuel blend, and wherein the mixture of five or more aryl ethers makes up at least 80 wt % of the fuel component, and
• wherein the fuel component is obtainable by reacting biomass pyrolysis oil comprising one or more phenols with one or more hydrocarbyl moieties having 1 to 10 carbon atoms forming one or more hydrocarbyl-ether bonds with the one or more phenols present in the biomass pyrolysis oil, and wherein the fuel blend comprises reacting biomass pyrolysis oil comprising one or more of the below formulae:
• with one or more compounds of the formula R1—Y,
• wherein
• R1 is:
• linear or branched C1-C10-alkyl, cycloalkyl, aryl, or naphtyl, wherein the aryl or naphtyl is unsubstituted or substituted with one two or three groups, independently selected from:
• C1-C5-alkyl, C1-C5-alkoxy;
• Y is halogen, vinyl, OH, MgX, where X is Cl or Br
• thereby obtaining one or more compounds of the formulae
