Abstract:
A fuel additive composition useful for incorporation in or admixture with fuels, particularly fuels containing vanadium and/or sodium as a contaminant such that upon combustion of the fuels containing or in the presence of said additive composition metal surfaces in contact with the resulting hot gaseous fuel combustion products are subject to less corrosion, contains one or more compounds providing the elements or elemental components magnesium, silicon, chromium and chlorine, these elements Mg, Si plus Cr, Cl being present in the additive composition in the weight ratio 1/>0.5/>1.0, respectively, the amount of Si to Cr being in the ratio 1:0.1-10.
Abstract:
A process for reducing oxidative degradation and cold flow of polymer crumb by immersing the crumb in a non-solvent such as water and/or dusting the crumb with a powder such as calcium carbonate and 2,6 di-t-butylparacresol, 4,4''-methylene-bis-(2,6 di-t-butylphenol) or other antioxidants. A process for reducing fluid flow friction loss in pipeline transmission of a hydrocarbon fluid by providing a continuous source of dissolved polymer therein by injecting polymer crumb or a slurry of polymer crumb and water into the hydrocarbon fluid, whereby the crumb gradually and continuously dissolves during transmission of the crumb through the pipeline.
Abstract:
A silicone is added in a minor proportion to a nonleaded gasoline to improve the distribution of the air-fuel mixture in the induction system of an aspirated multicylinder gasoline engine, thereby increasing operating efficiency.
Abstract:
GASOLINE CONTAINING AS AN IMPROVED ANTI-ICING ADDITIVE, THE COMBINATION OF A SUBSTITUTED TETRAHYDROPYRIMIDINE, AN AMIDE OR MIXTURES THEREOF AND AN ORGANIC SILICON COMPOUND. EXAMPLES OF THE TETRAHYDROPYRIMIDINE AND AMIDE ARE 1-OCTADECENYL-2-METHYL-1,4,5,6-TETRAHYDROPYRIMIDINE AND N-(I-AMINOETHYL)-N-HEPTADECENYLACETAMIDE. EXAMPLES OF SUITABLE ORGANIC SILICON COMPOUNDS ARE POLYHYDROCARBYLSILOZANES AND ALKYL SILICATES.
Abstract:
THE INVENTION COMPRISES THE USE OF CARBOLLYL METAL COMPLEXES AS ADDITIVES IN HYDROCARBON FUELS AND LUBRICANTS WHERE THEY FUNCTION AS COMBUSTION IMPROVERS, ANTIKNOCK AGENTS AND EXTREME PRESSURE AGENTS. SPECIFIC EMBODIMENTS INCLUDE USE IN FUELS FOR SPARK AND COMPRESSION IGNITION ENGINES, JET ENGINES AND ROCKETS.
