Abstract:
PROBLEM TO BE SOLVED: To obtain an additive composition for improving the low temperature flowability of a fuel oil. SOLUTION: A fuel oil composition comprises a fuel oil and a polymeric material selected from the group consisting of the following materials: an ethylene-unsaturated monomer copolymer; a comb polymer; a polar nitrogen compound; a polyoxyalkylene compound and a di-block hydrocarbon polymer. The polymeric material is incorporated in the fuel oil in a combination with at least two other low temperature flowability additives selected from the same group. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
Described herein are associative polymers capable of controlling formation of particulate matter from a non-polar ignitable composition upon ignition of the non-polar ignitable composition, alone or in combination with control of a physical and/or chemical property of the non-polar compositions and related compositions, methods and systems. Associative polymers herein described have a non-polar backbone and functional groups presented at ends of the non-polar backbone, with a number of the functional groups presented at the ends of the non-polar backbone formed by associative functional groups capable of undergoing an associative interaction with another associative functional group with an association constant (k) such that the strength of each associative interaction is less than the strength of a covalent bond between atoms and in particular less than the strength of a covalent bond between backbone atoms.
Abstract:
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.
