The invention relates to aqueous polymer dispersions comprising at least one polymer obtainable by the reaction of at least one monomer M1 of the general formula (I): H.sub.2CCHC(O)OR, wherein R is an unbranched alkyl chain comprising from 18 to 22 carbon atoms, and optionally at least one monomer M2. The invention relates moreover to a method for the preparing of such aqueous polymer dispersion and the use thereof as pour point depressant for crude oil, petroleum, and petroleum products.

The invention provides dispersions comprising I) at least one oil-soluble polymer effective as a cold flow improver for mineral oils, II) at least one organic, water-immiscible solvent, III) a dispersant comprising, based on the total amount of dispersant, a) 10-90% by weight of a salt of an ethercarboxylic acid and b) 90-10% by weight of a nonionic surfactant, IV) water and V) at least one organic, water-miscible solvent.

Systems for producing fuel compositions with predetermined desirable properties are disclosed. Feedback control can be employed to meter precise amounts of fuel composition components while monitoring fuel composition properties to obtain fuel compositions having specifically defined properties.

The present invention relates to a bioadditive for heavy oils that serves to reduce polluting emissions and bio-enhancer of the combustion performance for heavy oils, which comprises methyl esters of raps oil, also called raps biodiesel, in the range of up to 80% v/v, surfactants in the range of up to 80% v/v, diluents in the range of up to 20% v/v and metal oxides between 0.1-5 g/L.
