    Abstract: A residual fuel oil composition comprises a residual fuel oil, preferably at No. 6 fuel oil, having dissolved therein an effective total amount of at least one zirconium salt of (i) an alcohol, or (ii) a phenol, each having a C 2 to C 24 hydrocarbyl group, or (iii) of a hydrocarbyl sulfonic acid such that the salt has a mol. wt of 100 to 2500, or of any mixture thereof; said effective total amount of the salt(s) being sufficient to reduce the amount of particulate matter which will be formed when, in use, the residual fuel oil is combusted. Suitably 1 to 1000 ppm of zirconium salt(s), calculated as metallic zirconium, are present. Preferred zirconium salts are zirconium propoxide or dodecyl benzene sulfonate. The composition is suitable for combustion in industrial boilers and refinery furnaces, preferably being fed in air or steam-atomized form.

    Abstract: A residual fuel oil composition comprises a residual fuel oil, preferably a No. 6 fuel oil, having dissolved therein an effective total amount of at least one zirconium salt of a C 4 to C 22 , preferably C 6 to C, s, linear or branched chain aliphatic saturated or unsaturated carboxylic acid, or a tall oil, or of a naphthenic acid, or of any mixture thereof; said effective total amount of the salt(s) being sufficient to reduce the amount of particulate matter which will be formed when, in use, the residual fuel oil is combusted.
    Suitably 1 to 1000 ppm of zirconium salt(s), calculated as metallic zirconium, are present. Preferred zirconium salts are zirconium octanoate, its isomers, or mixtures thereof.
    The composition is suitable for combustion in industrial boilers and refinery furnaces, preferably being fed in air- or steam-atomized form.

    Abstract translation: 残余燃料油组合物包含残留燃料油，优选6号燃料油，其中溶解有效总量的至少一种C 4 -C 22，优选C 6至C 18的直链或支链脂族饱和或 不饱和羧酸或妥尔油，或环烷酸，或其任何混合物; 所述盐的有效总量足以减少在使用中残留燃料油燃烧时将形成的颗粒物质的量。 ...适合地，存在以金属锆计算的1至1000ppm的锆盐。 优选的锆盐是辛酸锆，其异构体或其混合物。 ...组合物适用于工业锅炉和炼油炉的燃烧，优选以空气或蒸汽雾化的形式进料。
