Abstract:
A fuel filter assembly that provides a constant level of least restricted fuel flow through the fuel filter assembly during the useful life of the filter media by utilizing the least possible amount of filter media to provide the least possible pressure differential over the filter media while also providing a constant level of fuel additive by exposing an amount proportional to the filter media required for the least possible restricted fuel flow. The fuel filter assembly utilizes a vertically upward housing that houses a filter media and a fuel additive. The fuel level slowly rises in the housing as the filter media becomes obstructed with contaminants and as the fuel additive dissolves over the life of the filter media. The top portion of the housing is made of a transparent material so that the level of fuel level may be easily determined, thereby allowing for an accurate and simple assessment of the useful life of the filter media and the fuel additive. The housing also provides a multi-purpose aperture provided in the top of the housing to provide for removal and/or replacement of the fuel additive and venting and priming of the housing. The filter media and fuel additive are entirely fabricated from combustible materials so that both may be easily discarded without cost and environmental concerns.
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.
Abstract:
A process for converting a hazy or potentially hazy water saturated alcohol-gasoline blend into a clear, stable gasoline composition having an improved octane rating. The conversion is made by adding to and blending with the hazy gasoline, a nonionic surfactant of an aminated polyisopropoxylated polyethoxylated alkylphenol.
Abstract:
Hybrid fuel microemulsions are prepared from diesel fuel, water, alcohol, and a novel surfactant system comprising N,N-dimethylethanolamine and a long-chain fatty acid substance. These fuels are characterized by high water tolerance and low-temperature stability, and are particularly adaptable to the utilization of aqueous ethanol as the alcohol source.
Abstract:
Magnesium-containing greases, particularly useful for bearing lubrication in high-temperature environments, are prepared by heating a mixture of magnesium hydroxide, magnesium oxide, hydrated magnesium oxide or a magnesium alkoxide; a carboxylic acid, a mixture thereof with a sulfonic acid, or an ester or salt of the same; water; and a liquid solubilizing agent for the acid, ester or salt. The amount of magnesium is such as to provide a basic grease.
Abstract:
This invention encompasses an improved process for injecting a homogenized water-hydrocarbon liquid fuel composition into blast furnace of the type wherein water and a liquid hydrocarbon fuel is homogenized and then atomized into a blast furnace under pressure to reduce coke consumption, the improvement which comprises introducing into the water-hydrocarbon liquid fuel composition usually prior to homogenization a metallic element in the form of a compound thereof, said metallic element being selected from the group consisting of magnesium, calcium, manganese, iron, cobalt, nickel, copper, zinc, aluminum, tin, lead, strontium, barium, zirconium, chromium, molybdenum, and tungsten in a quantity sufficient to provide 5-50 ppm as metal in the water-hydrocarbon liquid fuel composition whereby the efficiency of the blast furnace water-hydrocarbon liquid fuel injection is improved.In addition, from 100-10,000 ppm of a water-in-oil emulsifying agent may be incorporated into the water-hydrocarbon liquid fuel composition.
Abstract:
An energy-saving fuel additive for jet engines, gasoline and diesel engines, including additions to domestic heating and light industrial oils (#2 and #3) and residual or bunker fuel (#4, 5, and 6), which comprises as active ingredients a catalytic mixture of a major proportion of picric acid and a minor proportion of ferrous sulfate.
Abstract:
Arsenic containing fuel compositions are disclosed that will, upon combination, leave an ash that retains substantial proportions of said arsenic, thereby reducing its dissemination into the atmosphere. This result is obtained by adding to the fuel small amounts of a Mg, Ba, Zn, or Ni component. Also disclosed are certain fuel compositions containing both Mg and Zn additives that produce an ash containing arsenic in an essentially insoluble form.
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.
Abstract:
Process for preparing barium-containing dispersions in essentially inert diluents by contacting a basically reacting barium compound with carbon dioxide in the presence of a stabilizing agent and promoter. A typical process comprises carbonating a mixture of barium hydroxide monohydrate, heptyl phenol, and the reaction product of polyisobutenyl-substitutedsuccinic anhydride and an alkylene polyamine. The bariumcontaining dispersions thus produced are useful as additives for fuels and lubricants.
