Publication number: 20130239465Abstract: The cold flow of middle distillate fuels may be improved by adding an effective improving amount of one or more alpha-olefin compositions. The compositions include, but are not necessarily limited to, polymers of alpha-olefins per se, copolymerized or grafted alpha-olefins with maleic anhydride, acrylic acid, vinyl acetate, alkyl acrylates, methacrylic acid, and/or alkyl methacrylates. These resulting copolymers or grafted polymers may be blended with alkylphenol-formaldehyde resins, which in turn may be blended with ethylene-vinyl acetate (EVA) copolymer. In a non-limiting example, the cold filter plugging point (CFPP) may be synergistically improved as compared with the expected additive effect of using the components separately.Type: ApplicationFiled: March 6, 2013Publication date: September 19, 2013Applicant: Baker Hughes IncorporatedInventors: Ben Morgan, John A.
