Abstract:
PURPOSE: To prevent soluble components from falling out of a solution resulting in separation of an additive and poor fuel filterability by not employing polycyclic acids or their derivatives and controlling the percentage by mass of unsaturated acids including polyunsaturated acids, and of saturated acids in an additive. CONSTITUTION: The additive composition comprises an additive (a), comprising a plurality of monocarboxylic acids, each having from 10 to 24 carbon atoms, or acid derivatives thereof, less than 7 mass% of which acids or acids from which the derivatives are derived having a linear chain and being saturated, and the balance being unsaturated, at least 35 mass% of which balance being polyunsaturated.
Abstract:
Additive for fuels and lubricants containing spherical layered structure onion-like particles, containing solvent and dispersed therein carbon nanosized spherical clusters CNOs to the extent from 1 to 500 nm; these clusters consist of laminated partially closed cockleshell-like form graphene layers with substituents; and the additive for fuels and lubricants has the following ratio of components, wt. %: * - carbon nanosized spherical clusters - 10- 6 - 10- 1 ; • - solvent - rest. Additive for fuels and lubricants is used in the capacity of antifriction, antiscoring and anti-oxidant components in the production of petroleum, bioethanol, biodiesel fuels, oils, greases and technical fluids with anticorrosive and antifrictional properties.
