摘要： The present invention relates to a nitrogen-containing diesel solidification point depressant composition, and preparation and application thereof. The nitrogen-containing diesel solidification point depressant composition includes the following components in percentage by weight: 10-40% of monoisopropanolamine; 10-40% of cyclohexane; 0-20% of polyethylene glycol; and 40-60% of N-tetradecyl methacrylamide-tetradecyl methacrylate. After the prepared diesel solidification point depressant composition is added to commercially available 0 #diesel, a solidification point and a cold filter plugging point of the diesel are respectively depressed by 21-25° C. and 9-13° C.

摘要： This disclosure relates to compositions and methods of making an additized fuel composition comprising a base fuel composition and a randomly branched nitrate composition. The randomly branched nitrate composition includes a plurality of primary nitrate molecules, each molecule therein having an empirical chemical formula of CnNO3, wherein Cn is a branched aliphatic moiety which may be the same or different for each molecule, n is an integer selected from the group consisting of 8, 9, 10, 11 and 12, at least one carbon atom in the branched aliphatic moiety being bound to three or more carbon atoms, a branching index ranging from 1.8 to 2.2, and greater than 80% of the branches in the aliphatic moiety being in other than the alpha position. The additized fuel composition may be diesel fuel composition or a gasoline fuel composition. Such randomly branched nitrate composition may be more stable, and thus safer to handle than 2-ethylhexylnitrate and may have a lower overall nitrogen content, leading to lower NOx emissions upon combustion in diesel and gasoline fuel compositions.

摘要： Compositions corresponding to marine diesel fuels, fuel oils, jet fuels, and/or blending components thereof are provided that include at least a portion of a natural gas condensate fraction. Natural gas condensate fractions derived from a natural gas condensate with sufficiently low API gravity can provide a source of low sulfur, low pour point blend stock for formation of marine diesel and/or fuel oil fractions. Natural gas condensate fractions can provide these advantages and/or other advantages without requiring prior hydroprocessing and/or cracking.
