    Abstract: A low-emissions diesel fuel comprises a catalyzed blend of fatty acid esters, preferably derived from soybean oil and/or tallow and aviation kerosene. The catalyzed blend is effective in lowering regulated emission pollutants, among which are NOx, particulates, hydrocarbons and carbon monoxide. The catalyst will comprise fuel-soluble platinum and/or cerium or iron. The cerium or iron are typically employed at concentrations of from 2 to 25 ppm and the platinum from 0.05 to 2 ppm, with preferred levels of cerium or iron being from 5 to 10 ppm, e.g., 7.5 ppm, and the platinum being employed at a level of from 0.1 to 0.5 ppm, e.g., 0.15 ppm. A preferred ratio of cerium and/or iron to platinum is from 75:1 to 10:1. The jet fuel component will typically be employed at a volume ratio to the fatty acid esters of from about 2:1 to about 5:1, e.g., about 4:1. The full range of blends extends from 50:1 to 1:50 with some benefit. The jet fuel component of the blend preferably contains grade 55, 50-300 ppm detergent, 25 to about 500 ppm lubricity additive and 0.1-1 ppm platinum COD and 5-20 ppm cerium oleate or octoate. In addition to the fuel blend, a method is provided for reducing the emissions of pollutants from a diesel engine, comprising running the engine on a fuel as defined.

    Abstract: Non-polymeric fatty acid drag reducing agents are described herein. These additives are useful to reduce drag in hydrocarbon fluids and multiphase fluids of hydrocarbon(s) and water. No injection probes or other special equipment is expected to be required to introduce the drag reducing agent into the liquid stream, nor is grinding (cryogenic or otherwise) of the additive necessary to form a suitable drag reducing agent. The drag reducing additives of the invention are not subject to shear degradation and do not cause undesirable changes in the emulsion or fluid quality of the fluid being treated, or undesirable foaming. The drag reducing additives include fatty acids, alkoxylated derivatives of fatty acids, organic and inorganic salts of fatty acids and alkoxylated derivatives thereof, and esters of fatty acids and alkoxylated derivatives thereof, and mixtures thereof.

    Abstract: The additive described essentially comprises a selected alkoxylated fatty amine or fatty amine derivative and a special metal salt compound, preferably a metal soap. This additive for heavy oils effects a good emulsification or dispersion of asphaltenes and other higher-molecular weight compounds and, in addition, inter alia, increased storage stability, improved pumpability due to decreased viscosity of the oil and longer service lives of the filter systems. In addition, it also effects enhanced combustion of the heavy oils. The effective amount of additive in these oils is 2 to 2000 ppm. The oils described are suitable, in particular, as furnace fuel for industrial plants and power stations and as engine fuel for marine engines.

    Abstract: In this process for the selective noncatalytic reduction of the emission of pollutants from oil-fired boiler plants, chemical compounds which affect the combustion process are admixed, in solutions miscible with the liquid fuel, in metered amounts to the liquid fuel or to the combustion air, among these compounds being salts of organic acids, such as naphthenates, octoates, tallates, salts of sulfonic acids, saturated or unsaturated fatty acids, such as oleic acid, and tall oil, with metals from the group of K, Ba, Mg, Ca, Ce, Mn, Fe; rare earth metals; organometallic compounds, such as carbonyl compounds, mixed cyclopentadienylcarbonyl compounds, or aromatic complexes of the transition metals Fe or Mn. For the purpose of minimizing the NO.sub.x values in the waste gas and the dust load with economical consumption of chemicals, a reducing agent is introduced in metered quantities into the firebox (burner chamber) via a boiler metering system with the use of the liquid or also gaseous carrier stream as an aqueous solution of urea or also urea precursors, such as ammonia or ammonium carbonate, which can also contain further ingredients, such as alkanols, alkanecarboxylic acids, alkanals, or alkanones.
