Abstract:
A hydrocarbonaceous fuel additive, fuel composition, and method all lower both carbon particulate emissions and improve slag properties in combustion systems including, for instance, utility furnaces and boiler systems. The mixed metal catalyst may include a transition metal-containing compound, an alkali metal compound, and a magnesium-containing compound.
Abstract:
A method of reducing piston deposits, smoke or wear in a diesel engine. The method involves the step of running the engine on fuel comprising an oil soluble iron carboxylate or iron complex that includes Fe3+.
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:
The present invention relates to an apparatus and method for delivering molybdenum from a lubricant source into a fuel combustion system or to the exhaust therefrom. By the present invention, molybdenum from the lubricant or the fuel will interact with phosphorus, sulfur, and/or lead from the combustion products. In this manner, the molybdenum scavenges or inactivates harmful materials which have migrated into the fuel or combustion products, and which can otherwise poison catalytic converters, sensors and/or automotive on-board diagnostic devices. The present invention can also lead to improved durability of exhaust after treatment systems.
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.
Abstract:
A method of reducing smoke and particulate emissions from steam boilers and process heaters operating on liquid petroleum fuel by adding a fuel additive which contains an oil-dispersible iron compound and an over-based magnesium compound to liquid petroleum fuel.
Abstract:
A method of reducing smoke and particulate emissions from steam boilers and process heaters operating on solid fuel by adding a fuel additive which contains an oil-dispersible iron compound and an over-based magnesium compound to the solid fuel.
Abstract:
A catalyst and method for improving combustion efficiency in boilers, engines, and other equipment by adding to fossil and other fuels a fuel additive that contains an oil-soluble iron compound and an over-based magnesium compound and for which the median particle size of the additive is less than about 0.01 micrometers.
Abstract:
The present invention is a demulsifying and corrosion-inhibiting compound formed from the salt of an amphiphilic amine and an amphiphilic acid. In a preferred embodiment of the invention, the demulsifier may be a salt of an alkyl amine and an alkyl aryl sulfonic acid. Even more preferably, the demulsifier may be a salt of a methyl, di-cocoyl amine and an alkyl aryl sulfonic acid. According to another embodiment of the invention, an organic system may be demulsified by mixing the salt of an alkyl amine and an alkyl sulfonic acid with the system to be demulsified.
