Electric field mediated chemical reactors
View Patent ↗A chemical reactor includes two or more substrates joined along planar surfaces thereof, a chemical reaction chamber located between the two or more substrates, and a pair of electrodes on one of the substrates and along a wall of the reaction chamber. Each substrate is a substantially dielectric or semiconductor substrate. The chemical reaction chamber has a hollow interior, one or more input ports to transport a gas into the hollow interior, and an output port to transport a byproduct out of the hollow interior.
1. A chemical reactor, comprising:
two or more substrates joined along planar surfaces thereof, each substrate comprising dielectric or semiconductor;
a chemical reaction chamber formed between the substrates, the chemical reaction chamber having a hollow interior and
a pair of electrodes located on one of the substrates along a wall of the chamber, the chamber having one or more input ports to transport a gas into the hollow interior and an output port to transport a byproduct out of the hollow interior, and further comprising a chemical catalyst being on a portion of a wall of the chamber and being exposed to the hollow interior.
2. A chemical reactor, of claim 1 : wherein the pair of electrodes are separated by about 0.1 to 1 microns.
3. The chemical reactor of claim 1 , wherein the electrodes are insulated from the hollow interior by a dielectric coating.
4. The chemical reactor of claim 1 , wherein the substrates are chemically bonded together along surfaces thereof.
5. The chemical reactor of claim 1 , wherein the chamber comprises a plurality of physical flow obstructions positioned to cause a flowing gas to mix.
6. The chemical reactor of claim 1 , wherein the reaction chamber is a planar structure.
7. The chemical reactor of claim 1 , further comprising:
a third substrate being joined to a surface of a first of the two substrates and comprising dielectric or semiconductor, the first of the two substrates being located between the third substrate and the second of the two substrates; and
a second chemical reaction chamber being between the third substrate and the first of the two substrates and having a second hollow interior, a pair of electrodes being along a wall of the second chamber and on one of the third substrate and the first of the two substrates, the second chamber having an input port to transport a gas into the second interior and an output port to transport a byproduct out of the second interior.
8. The chemical reactor of claim 7 , wherein the chemical reaction chamber and second chemical reaction chamber are stacked so as to share a common input port and a common output port.
9. The chemical reactor of claim 1 , further comprising an AC voltage source connected across the electrodes and configured to drive the electrodes at a near-resonant frequency.
10. The chemical reactor of claim 1 , further comprising an impedance monitor connected to monitor of the impedance of the electrodes.
11. The chemical reactor of claim 1 , wherein the pair of electrodes are inter-digitized or interleaved with each other.
12. The chemical reactor of claim 1 , wherein the pair of electrodes are part of an RLC circuit.
13. The chemical reactor of claim 1 , wherein the chemical reaction chamber is configured to generate ions or free radicals in the gas.
