    摘要: A low pour point fuel oil composition is prepared from a major amount of a high pour point, low sulfur, waxy, residual fuel and a minor amount of low wax, low pour, residual fuel oil by adding thereto from 0.01 to 0.5% by weight of an oil soluble terpolymer such as vinyl acetate-ethylene-vinyl chloride or allyl chloride having a number average molecular weight of about 4,000 to about 70,000. The copolymer may be added either in a water-glycol emulsion or in a hydrocarbon to one of the blend components which has been heated to between about 25.degree. to 150.degree. C. In another aspect, this invention relates to a process for the pipeline transportation of the low pour fuel oil compositions previously described.

    摘要: The low temperature filterability of a petroleum middle distillate fuel, such as a heating oil or a diesel fuel is improved by adding to the fuel a flow improving amount of wool fat and, if desired, a flow improving amount of wool fat in combination with oil-soluble, auxiliary flow-improving material such as: an alkyl aromatic, e.g., the condensation product of chlorinated wax and naphthalene; a polymer of an acrylic ester, such as polyalkyl acrylate; etc. This invention is particularly advantageous in improving the flow of a diesel fuel through a fine filter at low temperatures.
