Abstract
Processes for making alkylate gasoline compositions that are more “green” and alkylate gasoline compositions containing “green” renewable naphtha and iso octane are described. Exemplary processes for making alkylate gasoline compositions that are more “green” and compositions of alkylate gasoline compositions containing “green” renewable naphtha, iso octane and iso pentane are described. Such compositions allow a higher mixing ratio of the renewable naphtha and/or a higher Research Octane Number (RON), Motor Octane Number (MON) and vapour pressure compared to not adding a combination of iso-octane and iso-pentane.

Process for preparing a gasoline composition, which process comprises:
- (a) admixing with a fossil alkylate base fuel containing:
- 90 vol-% or more C5-C12 paraffins,
- 5 vol-% or less of naphthenes,
- 1 vol-% or less of aromatics,
- 1 vol-% or less of oxygenates, and
- RON of at least 87,
- the alkylate base fuel being in an amount in the a range from 40 to 80 vol % based on total gasoline composition;
- (b) a renewable naphtha distillate containing:
- 90 vol-% or more C5-C12 paraffins,
- 30 vol-% or more C5-C6 paraffins,
- 5 vol-% or less of naphthenes,
- 1 vol-% or less of aromatics, and
- 1 vol-% or less of oxygenates,
- the renewable naphtha distillate being in an amount of 1 vol-% or more based on the total gasoline composition;
- and
- (c) one or more C6-C12 iso-paraffins having a RON of at least 95,
- the one or more iso-paraffins being in an amount in a range from 10 to 30 vol % based on the total gasoline composition.

Gasoline composition for a utility engine comprising:
- (a) a fossil alkylate base fuel in an amount in the a range from 40 to 80 vol % based on total gasoline composition, the fossil alkylate base fuel containing 90 vol-% or more C5-C12 paraffins;
- (b) a renewable naphtha distillate in an amount in a range from 3 to 10 vol % based on the total gasoline composition, the renewable naphtha-distillate containing
- 90 vol-% or more C5-C12 paraffins,
- 30 vol-% or more C5-C6 paraffins;
- and
- (c) one or more C6-C12 iso-paraffins in an amount in the a range from 10 to 30 vol % based on the total gasoline composition, the iso-paraffins having a RON of at least 95;
- wherein the gasoline composition comprises:
- 90 vol-% or more C5-C12 paraffins,
- 1 vol-% or less of naphthenes,
- 1 vol-% or less of aromatics,
- 1 vol-% or less of oxygenates,
- RON of at least 93, and
- wherein renewable content is determined by isotopic distribution involving 14C, 13C and/or 12C as described in ASTM D6866.

A renewable naphtha distillate formed as a renewable component in a small engine gasoline containing a major portion of a small engine gasoline of fossil origin and containing a minor portion of a renewable naphtha distillate, where the renewable naphtha distillate comprises:
- 90 vol-% or more C5-C12 paraffins,
- 30 vol-% or more C5-C6 paraffins,
- 5 vol-% or less of naphthenes,
- 1 vol-% or less of aromatics,
- 1 vol-% or less of oxygenates, and
- wherein a portion of the renewable naphtha distillate is in an amount of 3 vol-% or more, based on total gasoline composition, and wherein a renewable content is determined by isotopic distribution involving 14C, 13C and/or 12C as described in ASTM D6866.
