In order to blend fuels to meet specific regulatory and industry requirements, for instance octane requirements, different octane blending components can be used. One added component includes a composition of higher aromatics content. Unfortunately, this aromatic content may increase the particulate emissions of an internal combustion engine when the high aromatic fuel is combusted in that engine. As explained herein, reducing the aromatics content and replacing that octane increasing requirement with an alternative octane enhancer results in a formulated fuel that will have lower particulate emissions in the real-world driving of that engine as compared with a fuel having higher aromatic content.

Fuel composition and method of formulating a fuel composition to reduce real-world driving cycle particulate emissions

A process for improving the operation of combustors includes the steps of burning a carbonaceous fuel in a combustor system and determining combustion conditions within the combustor system that can benefit from a targeted treatment additive, wherein the determinations are made by calculation including computational fluid dynamics and observation. The process further includes locating introduction points in the combustor system where introduction of the targeted treatment additive could be accomplished. Based on the previous steps, a treatment regimen for introducing the targeted treatment additive to locations within the combustor system results in one or more benefits selected from the group consisting of reducing the opacity of plume, improving combustion, reducing slag, reducing LOI and/or unburned carbon, reducing corrosion, and improving electrostatic precipitator performance. The targeted treatment additive comprises an alloy represented by the following generic formula (A)(B)(C)(D)(. . .), wherein each capital letter and (. . .) is a metal, wherein A is a combustion modifier, B is a deposit modifier; C is a corrosion inhibitor; and D is a combustion co-modifier/electrostatic precipitator enhancer, wherein each subscript letter represents compositional stoichiometry, wherein n is greater than or equal to zero and the sum of n's is greater than zero, and wherein the alloy comprises at least two different metals, with the proviso that if the metal is cerium, then its compositional stoichiometry is less than about 0.7.

Method of using nanoalloy additives to reduce plume opacity, slagging, fouling, corrosion and emissions

A method of removing mercury or mercury-containing material from flue gas produced by a coal-burning main furnace includes feeding coal, which contains mercury or mercury-containing material, to a main furnace which produces flue gas. The method further includes feeding the coal to an auxiliary burner which produces a slipstream of flyash, feeding the slipstream of flyash from the auxiliary burner into the flue gas produced by the main furnace, and introducing a mercury-active oxidant to the coal being fed to the auxiliary burner, the combustion air fed to the auxiliary burner, and/or the flyash.
