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 method to produce acetylene, comprising:
introducing a fuel and oxygen into a fuel injection zone;
combusting said fuel and oxygen in a combustion zone to create a combustion gas stream;
cooling a sidewall of said combustion zone, wherein said cooling comprises flowing a coolant through at least one channel in said sidewall, wherein a portion of said coolant enters, via pores, said combustion zone through said sidewall;
accelerating the combustion gas stream and the portion of the coolant to supersonic speed in an expansion zone;
injecting feedstock into the combustion gas stream in a feedstock injection zone; and
reacting the feedstock to produce acetylene.

2. The method of claim 1 , further comprising injecting said coolant into said fuel injection zone.

3. The method of claim 1 further comprising heat protecting the combustion zone by surrounding the combustion zone with a thermal barrier.

4. The method of claim 1 wherein the fuel and the oxygen are mixed prior to introducing into the fuel injection zone.

5. The method of claim 1 further comprising a carrier gas introduced into the fuel injection zone.

6. The method of claim 5 wherein the carrier gas comprises at least one of water, a hydrocarbon, hydrogen, carbon monoxide, carbon dioxide, a promoter, a corrosion inhibitor, nitrogen, a noble gas, or combinations thereof.

7. The method of claim 1 wherein the feedstock comprises methane.

8. The method of claim 1 further comprising creating a shockwave and using the shockwave to heat the feedstock and combustion gas stream after the feedstock injection zone.

9. The method of claim 1 further comprising creating a shock train and using the shock train to heat the feedstock and combustion gas stream after the feedstock injection zone.

10. The method of claim 1 further comprising quenching the acetylene.

11. The method of claim 10 wherein the quenching comprising spraying the acetylene with water.
