Abstract:
A method and apparatus for converting crude oil tank bottoms to a liquid fuel, which uses a powered cutting tool to break up crude oil sludge contained in an oil storage tank bottom, with injection of cutter stock to facilitate break up of the sludge, an extraction pump to extract the sludge mixture comminution chamber and optional added cutter stock to reduce the particle size of solids to a uniform size range, to form a blend stock, which can be used to dilute a liquid fuel in an amount that will not adversely affect its product specification, whereby substantially all of the fuel value of the sludge is recovered.
Abstract:
This invention involves a process for achieving more energetic fuels by ug high density fullerenes and fullerene derivatives, mixed with liquid hydrocarbon or hydrocarbon derivative fuels. The advantages of the these materials are that they constitute a form of high density carbon which will evaporate or sublime quite easily by comparison to particles of carbon. The fullerenes, or derivatives of fullerenes, exist as molecules which are relatively volatile. These materials are generally solids and therefore easily compounded into hydrocarbon fuels slurries. The derivatives can be tailored for high solubility in hydrocarbon solvents. In addition, the fullerenes can be modified easily to adjust the oxidization susceptibility so that the residence time in the combustion zone can be shortened even further.
Abstract:
Methods for producing a combustible fuel product from a biological sludge are provided. A removable bulking agent is mixed with the sludge and the mixture aerobically composted under conditions effective to substantially reduce the level of pathogenic microorganisms and provide a fuel product with a heating value of about 3,800 Btu/lb after removal of the bulking agent.
Abstract:
A method for upgrading an aromatics-containing charge composition boiling in the gasoline boiling range comprises i) contacting the charge composition with a nitrating agent under nitrating conditions to form a product comprising nitrated aromatics; ii) hydrogenating a feed containing the product of i) under conditions sufficient to substantially reduce the nitro group of the nitrated aromatics so as to form a product comprising aromatic amines, water and heavy amines; and iii) removing the water and heavy amines from the product of step ii) to provide a gasoline boiling range product of an octane rating greater than the charge composition.
Abstract:
A fuel for use independently of atmospheric air by reaction with an oxidizer, has a metal hydride as a solid fuel component mixed into an inert liquid fuel component and 1.5 to 5.0 weight percent of a stearate as part of the solid fuel component. The liquid fuel component is preferably an easy flowing paraffin into which the stearate and the solid fuel component are mixed to form a liquified fuel that will react with a liquid oxidizer. The mixing is preferably performed at a temperature above 100.degree. C. and at a reduced pressure less than 10.sup.5 Pa.
Abstract:
A fuels conversion which consumes energy and produces an aqueous waste is combined with a pressurized wet combustion which charges the waste, converting its combustible contaminants to energy returned to the conversion, concurrently purifying the waste for use or disposal. The heating value of the contaminants may be supplemented by an extraneous fuel, using the waste as slurrying medium, so that the combination is made energy self-sufficient. Transfer of heat may be by direct contact between hot combustion products and fuel being converted. Other processes which produce aqueous waste and consume energy may similarly be combined with the wet combustion.
Abstract:
Coal liquid fractions to be used as fuels are stabilized against gum formation and viscosity increases during storage, permitting the fuel to be burned as is, without further expensive treatments to remove gums or gum-forming materials. Stabilization is accomplished by addition of cyclohexanol or other simple inexpensive secondary and tertiary alcohols, secondary and tertiary amines, and ketones to such coal liquids at levels of 5-25% by weight with respect to the coal liquid being treated. Cyclohexanol is a particularly effective and cost-efficient stabilizer. Other stabilizers are isopropanol, diphenylmethanol, tertiary butanol, dipropylamine, triethylamine, diphenylamine, ethylmethylketone, cyclohexanone, methylphenylketone, and benzophenone. Experimental data indicate that stabilization is achieved by breaking hydrogen bonds between phenols in the coal liquid, thereby preventing or retarding oxidative coupling.
