  • USE OF COLD FLOW IMPROVER COMPOSITIONS FOR FUELS, BLENDS THEREOF WITH BIOFUELS AND FORMULATIONS THEREOF
    Publication number: 20150059238
    Abstract: The present invention relates to the use of polyalkyl(meth)acrylates as an additive to fuels, especially middle distillate fuels and blends thereof. The present invention further relates to the use of a composition comprising polyalkyl(meth)acrylates as dispersing species susceptible to disperse waxes and sludgy material at low temperatures and a hydrocarbon solvent/an oil for improving the cold flow properties of fuel oil and fuel oil compositions. The present invention further relates to the use of these compositions as an additive to fuels, especially in the function of paraffin dispersant, to such fuels themselves and to fuel additive concentrates which comprise this composition dissolved in a hydrocarbon solvent or an oil.
