Plasma chemical device for conversion of hydrocarbon gases to liquid fuel
A system with a non-thermal, repetitively-pulsed gliding discharge reactor for converting gaseous hydrocarbons into liquid fuels efficiently. The system optionally contains a gas separator for removing non-hydrocarbon components from the gaseous hydrocarbon feed to improve efficiency of the system. The system may optionally reclaim hydrogen gas from the product gas for storage, transportation or power generation.
1. A system comprising:
a power source configured to provide high-voltage pulses;
a gliding discharge plasma reactor configured to convert a gaseous hydrocarbon to a liquid hydrocarbon composition, the gliding discharge plasma reactor comprising:
an inlet for the gaseous hydrocarbon,
a first outlet for the liquid hydrocarbon composition,
a second outlet for exhaust gases to exit the gliding discharge plasma reactor, wherein the exhaust gases comprise unreacted gaseous hydrocarbons and hydrogen, and
a plurality of first electrodes, each individually connected to the power source; and
a gas reclaimer in communication with the gliding discharge plasma reactor and configured to separate the hydrogen from the unreacted gaseous hydrocarbons, the gas reclaimer comprising:
an inlet for the exhaust gases,
a first outlet for the hydrogen, and
a second outlet configured to convey the unreacted gaseous hydrocarbons to the inlet of the gliding discharge plasma reactor,
wherein:
the system is configured to feed the exhaust gases from the second outlet of the gliding discharge plasma reactor to the inlet of the gas reclaimer.
2. The system of claim 1 , further comprising a cooler configured to cool the exhaust gases from the gliding discharge plasma reactor, wherein cooled exhaust gases from the cooler are fed into the gas reclaimer.
3. The system of claim 2 , wherein condensed hydrocarbon liquids from the cooler are fed into the inlet of the gliding discharge plasma reactor.
4. The system of claim 2 , wherein the cooler further comprises an outlet for a cooled mixture.
5. The system of claim 4 , wherein the cooled mixture is vented to an atmosphere.
6. The system of claim 1 , wherein the gaseous hydrocarbon of the inlet to the gliding discharge plasma reactor comprises a hydrocarbon gas and a diluent gas.
7. The system of claim 6 , wherein the diluent gas comprises nitrogen.
8. The system of claim 1 , wherein the hydrogen is used to produce power.
9. The system of claim 1 , wherein the gas reclaimer is a membrane-based system.
10. The system of claim 1 , wherein the gas reclaimer further comprises an outlet for venting non-reclaimed gasses.
