A method for bonding a fluid to a substance includes filling a first pressure vessel with the fluid and pressurizing the first pressure vessel to a first pressure. The fluid is the circulated through an electric arc formed within the first pressure vessel, thereby creating a treated fluid. Within a second pressure vessel, the substance is exposed to a magnetic field, thereby forming a polarized substance. The treated fluid and polarized substance are combined under a second pressure within a third pressure vessel, thereby exposing the treated fluid to the polarized substance at a pressure sufficient to achieve a bond.

Provided are methods for removing one or more components from a butanol based composition. The methods comprise providing a butanol based composition comprising one or more components, targeting at least one component or a combination thereof for reduction, and processing said butanol based composition such that the at least one targeted component is substantially removed. The butanol based composition can, for example, be bio-produced.

Methods of making fuel are described herein. A method may include providing a first working fluid, a second working fluid, and a third working fluid. The method may also include exposing the first working fluid to a first high voltage electric field to produce a first plasma, exposing the second working fluid to a second high voltage electric field to produce a second plasma, and exposing the third working fluid to a third high voltage electric field to produce a third plasma. The method may also include providing and contacting a carbon-based feedstock with the third plasma, the second plasma, and the first plasma within a processing chamber to form a mixture, cooling the mixture using a heat exchange device to form a cooled mixture, and contacting the cooled mixture with a catalyst to form a fuel.

An additive composition, on use in a fuel in a spark-ignition internal combustion engine, controls the formation of sludge and piston varnish. When used in a direct injection spark-ignition internal combustion engine, particulate emissions and deposit formation on intake valves may also be controlled. When used in a port fuel injection spark-ignition internal combustion engine, the port fuel injection valve deposits may be reduced. The additive composition comprises a polyalkylene amine and a hydrocarbyl-substituted hydroxyaromatic compound. The additive compositions may be present in a fuel composition.

The use as a sludge controlling additive in a fuel composition for a spark-ignition internal combustion engine or a compression-ignition gasoline internal combustion engine of a combination of: a. a hydrocarbyl-substituted aromatic compound; and b. a polyalkylene amine. The fuel composition may also be used for maintaining oil pathways and/or lubrication in an engine.

An enhanced fuel, a method of producing such enhanced fuel, and method of using such enhanced fuel for operating internal combustion engine. The fuel includes a mixture of at least one alcohol, water and ammonium nitrate (AN) as a cetane enhancer. The water is included in a quantity which renders the ammonium nitrate dissolved in the at least one alcohol. The fuel further contains dimethylether as an ignition-improver additive, at least one lubricity agent and at least one anti-corrosion agent.

The invention relates to a process for the conversion of hydrogen and one or more oxides of carbon to hydrocarbons, which process comprises: contacting hydrogen and one or more oxides of carbon with a catalyst in a reaction zone; removing from the reaction zone an outlet stream comprising unreacted hydrogen, unreacted one or more oxides of carbon and one or more hydrocarbons and feeding the outlet stream to a separation zone in which the outlet stream is divided into at least three fractions, in which; a first fraction predominantly comprises unreacted hydrogen, unreacted one or more oxides of carbon and hydrocarbons having from 1 to 4 carbon atoms; a second fraction predominantly comprises hydrocarbons having 5 to 9 carbon atoms, at least a portion of which hydrocarbons having from 5 to 9 carbon atoms are olefinic; and a third fraction predominantly comprises hydrocarbons having 10 or more carbon atoms; characterised in that at least a portion of the second fraction is recycled to the reaction zone.

The use as a particulate emissions and/or a complex poly-aromatic nuclei (CPAN) controlling additive in a fuel composition for a direct-injection spark-ignition internal combustion engine or a compression-ignition gasoline internal combustion engine of a combination of: a. a hydrocarbyl-substituted aromatic compound; and b. a polyalkylene amine.

The use as a piston varnish controlling additive in a fuel composition for a spark-ignition internal combustion engine or a compression-ignition gasoline internal combustion engine of a combination of: a. a hydrocarbyl-substituted aromatic compound; and b. a polyalkylene amine. The fuel composition may also be used for controlling power output, fuel economy, engine wear, piston ring sticking and blow-by.

The present application relates to a plant and a hydrocarbon production process comprising the steps of (i) in a conversion step converting at least a feed stream thereby obtaining a conversion effluent stream comprising water, hydrocarbons such as raw gasoline, unreacted and/or partially reacted feed and/or inerts, (ii) In a separator separating the conversion effluent stream into at least a raw gasoline stream, a recycle stream and a process condensate stream comprising water and oxygenates, (iii) mixing the feed stream and the recycle stream upstream the conversion step, and (iv) adding at least part of the process condensate stream to the feed stream and/or the recycle stream and/or the mixed feed-recycle stream from step (iii).
