Abstract
An additive composition for a fuel oil composition and that is free of polycyclic carboxylic acids and of acid derivatives thereof comprises an additive that comprises one or more monocarboxylic acids, each having from 10 to 24 carbon atoms, or acid derivatives thereof, optionally in combination with one or both of an anti-oxidant additive and an anti-static additive.
Claims13
An additive composition that is free of polycyclic carboxylic acids and of acid derivatives thereof, for a fuel oil composition, comprising:
- an additive, (a), comprising salt derivatives of a plurality of monocarboxylic acids, each having from 10 to 24 carbon atoms, less than 7 mass % of which acids from which salt derivatives are derived having a linear chain and being saturated, and the balance being unsaturated, at least 35 mass % of said balance being polyunsaturated.
An additive composition that is free of polycyclic carboxylic acids and of acid derivatives thereof, for a fuel oil composition, comprising or obtained by mixing:
- an additive, (a′), comprising salt derivatives of a plurality of monocarboxylic acids, each having from 10 to 24 carbon atoms, less than 7 mass % of which acids from which salt derivatives are derived having a linear chain and being saturated, and the balance being unsaturated, at least 35 mass % of said balance being polyunsaturated;
- and either or both of an additive, (b), in the form of an anti-oxidant additive and an additive, (c), in the form of an electrical-conductivity improver additive.
