摘要:
It has been discovered that jet fuel containing enhanced thermal stability additives and water can be delivered with a final water content of 15 ppm or less via existing jet fuel distribution system by controlling the fuel flow rate through the fuel delivery system comprising one or more filter coalescers and separator systems, said controlled fuel flow rate being determined by passing a sample of actual fuel through a sample of the fuel filter at various fuel flow rates to identify the flowrate at which the fuel effluent contains 15 ppm or less.

摘要:
The addition of biodiesel to petroleum-based kerosene jet fuels in very low concentrations can lower the temperature at which crystals appear in the fuel. The fuels can comprise a blend of a hydrocarbon base fuel component and, for example, up to 1000 ppm, v/v of the total fuel, of a biodiesel component comprising a lower alkyl ester of a fatty acid of natural origin having from 8 to 24 carbon atoms; these blends can be characterized by improved low temperature flow properties, especially of Cloud Point (ASTM D 2500), which can be lower than that of the petroleum fuel component without the alkyl ester, even in the presence of dissolved water up to the saturation level.

摘要:
The invention relates to methods and compositions for attaining acceptably low uptake of zinc and copper metals in a renewable component of a distillate boiling range fuel composition. The method can advantageously comprise the steps of providing the renewable component comprising blending a tallow ester feed and at least one of soybean oil ester feed and palm oil ester feed, such that the tallow ester feed comprises from about 35 vol % to about 90 vol % of the renewable component, and exposing the renewable component blend to a source of zinc or copper under conditions sufficient for copper and/or zinc to leach into the renewable component, but only to an acceptably low level.
摘要:
The present invention describes a method of making a jet fuel composition comprising: providing a mineral-based kero/jet-type distillate component having certain enumerated physico-chemical properties, typically an off-spec jet fuel; providing a deoxygenated and dewaxed renewable component derived from triglycerides and/or fatty acids and having an isoparaffin to normal paraffin ratio from about 2:1 to about 6:1 and an aromatics content less than about 1 vol %; and blending from about 75 vol % to about 97 vol % of the mineral-based distillate components with from about 3 vol % to about 25 vol % of the renewable component to form an on-spec blended jet fuel composition.
摘要:
Fuel compositions are provided which comprise synergistic combinations of a biodiesel or biodiesel blend, an antioxidant comprising a mixture of at least one diphenol and at least one sterically hindered phenol, and a cetane improver. The fuel compositions described herein exhibit a unique combination of improved oxidation stability and enhanced ignition quality.
