Abstract:
A method of improving the combustion of a fuel by adding a catalyst or combustion enhancer at an extremely low concentration, preferably in the range of 1 part catalyst per 200 million parts fuel to 1 part catalyst per 6 trillion parts fuel. The catalyst or combustion enhancer may be selected from a wide range of soluble compounds. The method may comprise the steps of an initial mixing of the catalyst or enhancer with a suitable solvent and then subsequent dilution steps using solvents or fuel. Suitable solvents include water, MTBE, methylketone, methyisobutylketone, butanol, isopropyl alcohol and other hydrophilic/oleophilic compounds.

Abstract:
Fuel additives are disclosed for high-asphaltene carbonaceous fuels such as residual fuel oil or coal. Such additives provide improved combustion characteristics. Such improved combustion characteristics include one or both of improved efficiency and decreased emissions of pollutants. In particular, the fuel additives include an extract from a plant such as fescue, alfeque, or alfalfa, and optionally, an organometallic compound. The use of a fuel additive including both a plant extract and an organometallic compound is particularly useful in improving the combustion characteristics of fuels with particularly high asphaltene content.
Abstract:
Tropospheric volume elements enriched with vital elements and/or protective substances as well as procedures for their production and application. The term “vital elements” applies to all matter supporting the development of life within the earth's biosphere and the term “protective substances” means all those substances which contribute directly or indirectly to the prevention of harmful effects on the earth's biosphere and in particular on man. Tropospheric volume elements in the form of clouds which contain contaminants and which can escape from industrial facilities due to damage or malfunction are enriched with protective substances which prevent the organism from taking in radioactive elements and minimize the extent of the area affected by the clouds and possess additional warning and identification properties.
Abstract:
Emissions of pollutants from diesel engines are reduced by a combination of mechanical devices and fuel additives. In one series of embodiments, diesel emissions of NO.sub.x and particulates are reduced, simultaneously with gaseous hydrocarbons and carbon monoxide, by the combined use of exhaust gas recirculation or engine timing modification, with a particulate trap and a platinum group metal catalyst composition. In another embodiment, a multi-metal catalyst composition, comprising a combination of a platinum metal catalyst composition and at least one auxiliary catalyst metal composition, especially cerium or copper, is employed to provide catalyst metal to the exhaust system including a diesel trap to lower the balance point of the particulate trap (the temperature at which the rate of trap loading equals the rate of regeneration) while also lowering the emissions of carbon monoxide and unburned hydrocarbons. Data for platinum, copper and cerium catalysts establishes effective amounts. Tests also show selective maintenance of low oxidation of SO.sub.2 to SO.sub.3.
Abstract:
An improved lubricity water and diesel fuel emulsion is presented. The emulsion is used as fuel for diesel engines, and includes a lubricity additive selected from the group consisting of dimer acids, trimer acids, phosphate esters, sulfurized castor oil, and mixtures thereof.
Abstract:
This invention relates to the preparation of clear, bright oil-soluble aluminum-containing compositions of high aluminum content; to the resulting products; and to the use of such products; for example, as fuel additives such as additives employed in turbine fuels as corrosion inhibitors and other uses.
