The present embodiments describe a method to reduce vanadium corrosion in a gas turbine by adding an oleophilic corrosion inhibitor into a combustion fuel, in which the oleophilic corrosion inhibitor comprises carbon black support particles and magnesium bonded to the carbon black support particles. The carbon black support particles comprise a particle size less than 40 nanometer (nm), and oxygen content less than 1 weight percent (wt %), and a surface area of at least 50 square meters per gram (m.sup.2/gram).

A fuel composition that provides a renewable biofuel energy source for reducing dependence on fossil fuels and improving air quality by reducing the amount of carbon monoxide released into the air during combustion. The fuel composition includes an energy crop comprising: a solid granular component being suspended in a liquid non-petroleum plant based fuel. The liquid fuel containing the granular component is efficacious in releasing copious quantities of vapor for burning. The vapor provides a more complete and efficient burn. The fuel composition further comprises an oxidizing agent for removing a plurality of electrons from the granular component during combustion, and/or an additive that imparts a change in the physical properties of the fuel composition.

A fuel composition for use in internal-combustion engines has a fuel component, an alcohol component, a water component, a microemulsion blend, and a cetane-enhancer component. The microemulsion blend includes at least one of lower grade fatty acid derivatives being present in an amount effective for the fuel, alcohol, and water components to form a microemulsion blend. The emulsifier is present in an amount effective for the biodiesel fuel, alcohol, water, and emulsifier to form an emulsion.

Motor fuel compositions containing ethanol, also known as gasohol, are disclosed, wherein the motor fuel is substantially in one phase and contains, 1 to 50, preferable 2 to 30 weight % of ethanol and an amount of water between 1 and 10 wt. % on the basis of the weight of the ethanol. Such motor fuel compositions can be produced by blending gasoline with hydrous ethanol, thus evading the necessity to use anhydrous ethanol as feedstock. Furthermore such motor fuel compositions may be produced by blending gasoline with hydrous ethanol and anhydrous ethanol, thus evading the necessity to use anhydrous ethanol as the sole feedstock. These motor fuel compositions may contain a second liquid phase that does not form a separate layer, and where no separate liquid phase can be detected by vision, and so meets with the specification that has become known as “clear and bright”.

Disclosed here are systems and methods including one or more FBCs and one or more suitable aftertreatment devices, including DOCs, DPFs, and suitable combinations thereof. The systems and methods disclosed may include selecting a suitable FBC for use with a fuel with a specified sulfur content. Systems and methods disclosed here may also include using one or more ECUs to control one or more FBC dosing/metering devices to supply FBCs from one or more FBC reservoirs in the presence of a specified event.
