International Classification:

C10L 1/04
C10G 32/02

Abstract:

The present invention provides a method of incorporating a gaseous hydrocarbon into a liquid hydrocarbon. The method comprises steps of exposing a gaseous hydrocarbon to non-thermal plasma generated using a reduced electric field with an E/N ratio in a range of from about 10 to about 30 Td to activate the gaseous hydrocarbon, and contacting the activated gaseous hydrocarbon with the liquid hydrocarbon to incorporate the gaseous hydrocarbon into the liquid hydrocarbon. The method provides the advantages of low energy consumption and relatively low capital expenditure.

Abstract:

A reactor for reforming a liquid hydrocarbon fuel, and associated processes and systems, are described herein. In one example, a two stage process is disclosed in which a first reactor is coupled to a second stage reactor having a reaction volume greater than the first reactor. In the first reactor, the liquid hydrocarbon fuel is partially reformed and thereafter is inputted into the second stage reactor for complete partial oxidation. The reaction product is at last partially synthesis gas, a mixture of carbon monoxide, hydrogen, as well as other low hydrocarbons such as methane, ethylene, ethane, and acetylene. The low hydrocarbons can be reformed further in a solid oxide fuel cell. A portion of the gaseous, rotating contents of the second stage reactor may be input into the first reactor to help generate and sustain rotation within the first reactor.

International Classification:

C02F 1/48

Abstract:

A treatment system for treating water, such as produced water that is produced during hydraulic fracturing. The system employs a combination of a plasma spark discharge and an RF oscillating electric field. The plasma spark discharge and the RF oscillating electric field may be employed simultaneously or in an overlapping manner within a chamber to treat the water. The treatment system is able to kill microorganisms as well as reduce or eliminate fouling due to, for example, bicarbonates. In some embodiments, grids are employed to further enhance the heat produced by the RF oscillating electric field.
