Abstract

A reactor comprising a thermal barrier surrounding a combustion zone. The reactor further comprises a cooling jacket inner wall and a binder disposed between the cooling jacket inner wall and the thermal barrier, and a cooling jacket outer wall, wherein the cooling jacket inner wall and the cooling jacket outer wall define a cooling channel. The reactor further comprises an outer reactor wall disposed over the cooling jacket outer wall, wherein the outer reactor wall is impermeable and is configured to contain high pressure gas within the reactor.

First claim

The invention claimed is:

1. A shockwave reactor, comprising:
a single thermal barrier said thermal barrier comprising yttria-stabilized zirconia, said yttria stabilized zirconia comprises 3 to 20 mass percent yttria oxide, wherein said thermal barrier surrounds a combustion zone;
a cooling jacket inner wall;
a binder comprising an alloy of copper disposed between said cooling jacket inner
wall and said thermal barrier;
a cooling jacket outer wall, wherein said cooling jacket inner wall and said cooling jacket outer wall define a cooling channel and where said cooling jacket inner wall and said cooling jacket outer wall are limited to a portion of the shockwave pyrolytic reactor including the fuel injection zone, the combustion zone and the expansion zone; and
an outer reactor wall disposed over said cooling jacket outer wall, wherein said outer reactor wall is impermeable and is configured to contain high pressure gas within said reactor.

2. The reactor of claim 1 , wherein said yttria stabilized zirconia comprises about 7 mass percent yttria oxide.

3. The reactor of claim 1 , wherein said thermal barrier has a thermal conductivity of between about 0.1 W·m −1 ·K −1 to about 10 W·m −1 ·K −1 .

4. The reactor of claim 1 , wherein said binder has a thermal conductivity of between about 10 W·m −1 ·K −1 and 150 W·m −1 ·K −1 .

5. The reactor of claim 1 , wherein said cooling jacket inner wall comprises a copper alloy and has a thermal conductivity of at least about 200 W·m −1 ·K −1 .

6. The reactor of claim 1 , further comprising insulation covering said outer reactor wall.

7. The reactor of claim 1 , further comprising a plurality of baffles disposed between said cooling jacket inner wall and said cooling jacket outer wall.

8. The reactor of claim 1 , wherein:
a portion of said cooling jacket inner wall is formed to include perforations therethrough;
said binder is porous; and
said thermal barrier is porous.

9. The reactor of claim 1 , wherein a portion of said cooling jacket inner wall, said binder, and said thermal barrier, are formed to include perforations therethrough.

10. A shockwave pyrolytic reactor, comprising:
a fuel injection zone;
a combustion zone adjacent to said fuel injection zone;
an expansion zone adjacent to said combustion zone, said expansion zone configured to accelerate a carrier stream to supersonic speed;
a feedstock injection zone adjacent to said expansion zone, said feedstock injection zone configured to inject feedstock into said carrier stream;
a mixing zone adjacent to said feedstock injection zone, said mixing zone configured to mix said carrier stream and said feed material;
a reaction zone adjacent to said mixing zone;
a single thermal barrier said thermal barrier comprising yttria-stabilized zirconia, said yttria stabilized zirconia comprises 3 to 20 mass percent yttria oxide, wherein said thermal barrier surrounds said fuel injection zone, said combustion zone, and said expansion zone;
a cooling jacket inner wall;
a binder comprising an alloy of copper disposed between said cooling jacket inner wall and said thermal barrier;
a cooling jacket outer wall, wherein said cooling jacket inner wall and said cooling jacket outer wall define a cooling channel and where said cooling jacket inner wall and said cooling jacket outer wall are limited to a portion of the shockwave pyrolytic reactor including the fuel injection zone, the combustion zone and the expansion zone; and
an outer reactor wall disposed over said cooling jacket outer wall, wherein said outer reactor wall is impermeable and is configured to contain high pressure gas within said reactor.

11. The reactor of claim 10 , wherein said thermal barrier comprises yttria-stabilized zirconia and has a thermal conductivity of between about 0.1 W·m −1 ·K −1 to about 10 W·m −1 ·K −1 .

12. The reactor of claim 10 , wherein said binder has a thermal conductivity between about 10 W·m −1 ·K −1 and 150 W·m −1 ·K −1 .

13. The reactor of claim 10 , wherein said cooling jacket inner wall comprises a copper alloy and has a thermal conductivity of at least about 200 W·m −1 ·K −1 .

14. The reactor of claim 10 , further comprising insulation covering said outer reactor wall.

15. The reactor of claim 10 , wherein:
a portion of said cooling jacket inner wall is formed to include perforations therethrough;
said binder is porous; and
said thermal barrier is porous.

16. The reactor of claim 10 , wherein a portion of said cooling jacket inner wall, said binder, and said thermal barrier, are formed to include perforations therethrough.
