Use of an additive mixture containing homopolymer of a hydrocarbylvinyl ether for improving the action of a cold flow improver for fuel oil compositions and for decreasing the Cold Filter Plugging Point with avoidance of aspiration

摘要

Use of an additive mixture containing:(i) as component A at least one homopolymer of a hydrocarbylvinyl ether for improving the action of a cold flow improver for fuel oil compositions, (ii) as component B at least one conventional cold flow improver for decreasing the Cold Filter Plugging Point (CFPP) value of the fuel oil composition and optionally to decrease the CFPP2-value and/or avoid an aspiration value is new. Independent claims are included for: (1) a fuel oil composition containing a main quantity of a hydrocarbon fuel and an active amount of the additive mixture as defined above and optionally at least one other conventional additive; (2) a fuel oil composition where the fuel is diesel oil, fuel oil, or kerosene; (3) diesel fuel obtainable by refining, coal distillation, or gas liquefaction, or a mixture of diesel fuel and optionally regenerative fuel; (4) an additive concentrate containing an additive mixture as defined above and at least one diluting agent and optionally at least one further additive.
