    Abstract: The invention presented is a process for reducing the nitrogen oxides concentration in the effluent from the combustion of a carbonaceous fuel. The inventive process comprises introducing into the effluent an oxygenated treatment agent which includes an oxygenated hydrocarbon under conditions effective to oxidize nitric oxide in the effluent to nitrogen dioxide and to produce ammonia; and contacting the effluent with an aqueous absorbing solution having a component capable of causing nitrogen dioxide to be absorbed into the solution.

    Abstract: A process for the reduction of nitrogen oxides in an effluent from the combustion of a carbonaceous fuel while minimizing the production of other pollutants is presented. The process comprises introducing (most commonly by injecting) a nitrogen oxides reducing treatment agent into an effluent according to a nitrogen oxides reducing treatment regimen under conditions such that the treatment agent is operating on the high temperature or right side of its nitrogen oxides reduction versus effluent temperature curve, especially on the high temperature or right side of the curve plateau.

    Abstract: The invention provides gasoline additive compositions comprising solutions of at least one fuel-soluble platinum group metal compound in a solvent miscible in the gasoline, the platinum group metal complex being present in an amount sufficient to supply from 0.01 to 1.0 parts per million of the platinum group metal when added to a predetermined amount of gasoline.Preferred solvents are oxygenated hydrocarbons such as ethanol, tetrahydrofuran, and methyl tertiary butyl ether, and will preferably be employed in amounts of less than 5% of the weight of the gasoline to provide oxygen and the metal at a weight ratio of from 1,000:1 to 100,000:1. Especially preferred compounds are those of the formula:X M.sup.II R.sub.2wherein X is a cyclooctadienyl ligand; M is a platinum group metal; and R is benzyl, phenyl or nitrobenzyl.The additive compositions and fuel treated therewith improve operating efficiency of internal combustion engines in terms of increased power output per unit of fuel burned and reduce the emissions of particulates and noxious gases such as carbon monoxide and nitrogen monoxide. The additives provide beneficial results upon immediate use and over long periods of continuous use.
