  • Patent number: 5693106
    Abstract: Platinum group metal fuel additives are effective in fuel environments which make the exclusion of water impractical. The fuels additives comprise a platinum group metal compound and a water-functional composition selected from the group consisting of lipophilic emulsifiers, lipophilic organic compounds in which water is miscible and mixtures of these. The additives are preferably effective in fuel compositions having water contents of at least about 0.01% water by weight.

  • Patent number: 5584894
    Abstract: The present invention relates to a process for reducing nitrogen oxides emissions from a diesel engine, which comprises preparing an emulsion of water in diesel fuel which contains a catalytically effective amount of catalyst composition and a lubricity additive, and supplying said emulsion to a diesel engine for combusting therein, whereby combustion of the emulsion leads to a reduction in the nitrogen oxides emissions from the diesel engine when compared with combustion of diesel fuel alone.

  • Patent number: 5501714
    Abstract: The invention provides a method employing a fuel additive to improve the operation of a pass-through oxidation catalyst over long periods of time with continued catalytic activity and without the undesirable conversion of SO.sub.2 to SO.sub.3. A pass-through catalyst support is continuously, selectively catalyzed by the combustion of a fuel containing a platinum group metal composition which burns to release the catalyst metal in active form. The effectiveness of the process is attributed to improved combustion in the engine by the catalyst and the treatment of the catalytic oxidizer with active catalyst metal released during combustion such that, in the exhaust system, the soluble organic fraction of the particulates and the levels of gaseous unburned hydrocarbons and carbon monoxide are significantly reduced. The catalysts conditioned by the present invention cause minimal conversion of SO.sub.2 to SO.sub.3.

  • Patent number: 5342592
    Abstract: The removal of sulfur oxides (SO.sub.x) and nitrogen oxides (NO.sub.x) from combustion effluents is enhanced by the supplying of reactants in a particular distribution pattern in the gas flow. To achieve the particular distribution pattern and to avoid impingement of the reactant on the heat exchanger tubes of the combustor, an elongated injection lance comprising c cooling jacket and plural spaced injections ports is employed. The cooling jacket protects the reactant supply to the injection ports from the high temperatures of the combustion gases.

  • Patent number: 5266083
    Abstract: The invention presented relates to a method for reducing the emission of nitrogen oxides from a diesel engine without significant loss of fuel efficiency and without significant increases in carbon monoxide and hydrocarbon emissions. The method involves preparing a diesel engine such that the injection timing thereof is set at a point sufficient to obtain reductions in the nitrogen oxides emissions from the engine; and firing the diesel engine with a diesel fuel having admixed therein an additive which comprises a fuel soluble organometallic platinum group metal coordination composition.

  • Patent number: 5057293
    Abstract: A process is presented for reducing the concentration of pollutants in an effluent from the combustion of a carbonaceous fuel. The process comprises introducing a first treatment agent into the effluent at a first temperature zone to reduce the concentration of a first pollutant and introducing a second treatment agent into the effluent at a second temperature zone to reduce the concentration of either the first pollutant or a second pollutant, wherein the first and second treatment agents are introduced under conditions effective to reduce the effluent pollution index.

  • Patent number: 4863704
    Abstract: A process is presented for reducing the concentration of pollutants in an effluent from the combustion of a carbonaceous fuel. The process comprises injecting a first treatment agent into the effluent at a first temperature zone and injecting a second treatment agent into the effluent at a second temperature zone, wherein the first and second treatment agents are injected under conditions effective to reduce the effluent pollution index. At least one of the treatment agents comprises an ammonium salt of an organic acid having a carbon to nitrogen ratio of greater than 1:1.

  • Patent number: 4830839
    Abstract: This invention presents a process for performing ammonia scrubbing. More particularly, the present invention comprises a process in which a non-nitrogenous treatment agent is introduced into the effluent so as to interact with ammonia present in the effluent under conditions effective to perform ammonia scrubbing, i.e., at least partially rid the effluent of ammonia.
