Abstract:
Use of a composition comprising a base formulation of one or more alkyl esters of a C6-C16 carboxylic acid or mixtures thereof as a fuel composition is provided. The use of the fuel composition is specifically provided for use as a lamp fuel, a lighter fuel, and/or a fuel for cooking, heating or cooling. Specifically, use of a composition as a lamp fuel is provided, wherein the composition comprises by weight 35-45% C8 methyl esters, 25-35% C10 methyl esters, 15-25% C12 methyl esters, and/or 5-15% C14 methyl esters. Also provided is a method for producing a fuel composition comprising the steps of a) providing a vegetable oil, b) preparing alkyl esters of carboxylic acids comprised in said vegetable oil by esterification and/or transesterification, c) optionally isolating one or more of said alkyl esters of said carboxylic acids, wherein said alkyl esters of carboxylic acids comprised in said vegetable oil and/or said one or more isolated alkyl esters constitute said fuel composition.
Abstract:
A method and composition for identifying chemically tagged petroleum products can be achieved by adding one or more chemicals to a selected petroleum product wherein the chemical is immune to extraction from the petroleum product by conventional inexpensive absorbents, cannot be removed by extraction with acids, bases, or immiscible solvents, cannot be easily oxidized, reduced or reacted with common agents, is difficult to disguise by masking with other agents, has a low polarity, and has a boiling point in the range of the petroleum product the chemical is being added to. The presence of the chemical is determined by using ion mobility spectroscopy.
Abstract:
A method of inhibiting the deposition of paraffin wax, asphaltene, or mixtures thereof in a crude oil contaminated with paraffin wax, asphaltene, or mixtures thereof and susceptible to such depositions comprising the step of incorporating into said crude oil an effective deposition inhibiting amount of an oil soluble organic compound having at least one oleophobic and hydrophobic fluoroaliphatic group, and antideposition stabilized crude oil compositions containing said compound, are disclosed.
Abstract:
The present invention provides a procedure for removing mineral matter and water from a primary bitumen froth recovered from tar sands which comprises diluting the raw bitumen froth with a hydrocarbon diluent boiling in the range of 350*-750*F. and thereafter settling the diluted bitumen froth in an autoclave settling zone to provide a froth product and a tailings product. The tailings product is thereafter subject to centrifugal force to provide a centrifugal tailings product and a centrifugal froth product. The centrifugal froth product is recycled to the settler zone.
Abstract:
An improved method for processing bitumen froth containing water, mineral matter, and bitumen to provide a froth product substantially reduced in water and mineral matter which comprises diluting the bitumen froth with a liquid hydrocarbon diluent boiling in the range of 350*-750*F., thereafter subjecting said diluted froth to centrifuging and settling steps, said settling conducted at elevated temperature and pressure to provide a bitumen froth product substantially reduced in water and mineral matter.
Abstract:
A composition for dispensing toxic agents, such as an insecticide, comprises an internal combustion engine fuel containing a minor amount of an insecticide which is refractory to the fuel combustion conditions of the engine and soluble in the fuel. The engine fuel claimed is gasoline or a gasoline/kerosene mixture, although diesel fuels are also disclosed. The proportion of insecticide in the mixture is low enough to enable operation of the engine to power a vehicle such as a lawn mower and high enough to be effective in the engine exhaust against target pests. In use, a gasoline fuel containing up to 10% by weight of malathion is employed to operate an internal combustion engine powering an implement such as a lawn mower and the insecticide is dispensed via the engine exhaust over the ground traversed by the implement.
Abstract:
A process and apparatus for the separation of the sand component from an admixture of bitumen or oil, sand and water such as bituminous sands derived from the Athabasca tar sands located in the Province of Alberta, Canada in which a mass of the admixture is compacted and directed against a displaceable oleophilic surface to apply a thin layer to such surface and driving the surface at a rate sufficient to dislodge the sand from the applied layer and recovering the bitumen-enriched residue adhered to the surface.
