| 摘要 |
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 C4 to C22, preferably C6 to C18, 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. |
