    Abstract: Heavy fuel oils or residual fuel oils can be stabilized with magnesium over-based compounds such as magnesium overbased carboxylates. It was surprisingly discovered that adding magnesium overbased carboxylates to the residual fuel oils shortly after thermal cracking gave much better results than can be achieved after the application of the carboxylates to the fuel oil after storage. Further, compounds containing at least about 21 wt % magnesium also give better results than compounds with 18 wt % or less, in one non-limiting embodiment. Magnesium overbased compounds can also be added to coker feedstocks to reduce coker furnace fouling. Treatment with the methods of this invention reduces asphaltene deposits and sludges.

    Abstract: Fuel compositions comprising a major amount of a normally liquid fuel and a minor amount of a hydroxylamine or a salt thereof, more often wherein each hydroxylamino group of the hydroxylamine or salt thereof contains no more than one tertiary alkyl substituent. The hydroxylamine or salt thereof provide improved combustion properties to a wide variety of normally liquid fuels, including hydrocarbon based fuels, oxygenates and synthetic fuels.

    Abstract: A method of reducing the negative effects of accumulation of ash in a diesel fuel combustion system includes supplying a diesel fuel having an additive that includes a manganese compound to a diesel fuel combustion system. The combustion system includes a catalyzed diesel particulate filter or, alternatively, a continuously regenerating technology diesel particulate filter. The fuel is then combusted in the combustion system to product at least one byproduct that includes the manganese compound. The manganese compound is supplied in an amount effective to complex with the combustion byproduct.
